The single dad’s baby wouldn’t stop crying on the plane — until a single mother did the unthinkable. 37,000 ft above ground, and Derek had never felt more alone. His 8-month-old daughter, Rosie, was screaming—the raw, desperate kind of cry that makes strangers stare and mothers look away. Sweat slid down his temple. His hands shook. Every passenger from row 12 through 18 was glaring, whispering, judging. A man in a business suit muttered something about controlling your kid. A flight attendant approached with that tight smile that meant trouble. Derek closed his eyes, pulled Rosie closer, and whispered the only words he knew: “I’m sorry, baby. Daddy’s trying.”

Then she appeared. A woman from the row across stood without a word. She didn’t ask permission. She simply reached out, lifted Rosie from his trembling arms, and did something no stranger should ever do. The cabin went silent. Derek’s heart stopped—and what happened next would haunt him for eight months, until he finally understood why she did it.

The redeye from Chicago to Seattle was supposed to be simple. Derek had planned everything down to the minute: the feeding schedule, the diaper bag packed with military precision, the white-noise app downloaded on his phone. He’d read every article, watched every video, asked every single dad in his support group for advice. Eight months of solo parenting had taught him that preparation was the only thing standing between him and complete disaster.

But Rosie had other plans. She started fussing somewhere over Nebraska. By the time they crossed into Wyoming, the fussing had turned into full-blown wailing. Derek tried the bottle—she pushed it away. He tried the pacifier—she spat it out. He tried rocking, bouncing, humming every lullaby he could remember from his childhood. Nothing worked. The crying got louder, more urgent, as if Rosie was trying to tell him something he couldn’t understand.

Shame pressed on his chest. He knew what the other passengers were thinking; he saw it in the woman in front of him, sighing dramatically; in the elderly couple across the aisle exchanging knowing glances. They were thinking what everyone always thought when they saw him alone with Rosie: that he was doing it wrong; that he didn’t know what he was doing; that a baby needed her mother and he was just a poor substitute trying his best. They weren’t entirely wrong. Eight months ago, Derek had no idea how to change a diaper. Eight months ago, he couldn’t tell a hungry cry from a tired one. Eight months ago, his wife, Madison, was supposed to be here doing all the things that seem to come so naturally to mothers. But Madison had held Rosie exactly once—for 37 seconds in the delivery room—before the hemorrhaging started. Before the doctor stopped smiling. Before Derek’s world collapsed into a single sentence: We did everything we could.

Now here he was, alone on a plane with a screaming baby and no idea what to do next. The flight attendant was making her way down the aisle, that practiced smile fixed like a warning. Derek braced for the lecture, the thinly veiled suggestion that maybe he should take Rosie to the back of the plane—away from the paying customers who didn’t sign up for this. That’s when the woman stood.

She’d been in the window seat across from him; he hadn’t noticed her until that moment. Dark hair pulled into a messy ponytail. Tired eyes like she hadn’t slept in days. A little girl curled beside her—maybe four—fast asleep against the window with a stuffed rabbit clutched to her chest. The woman didn’t look at Derek. She didn’t ask if he needed help. She stood, crossed the narrow aisle, and held out her arms.

“Give her to me,” she said. It wasn’t a question.

His first instinct was to refuse. Strangers don’t just take other people’s babies. But something in her voice—a quiet authority from somewhere deeper than politeness—made him hesitate. In that hesitation, the woman lifted Rosie from his arms as if it were the most natural thing in the world.

The cabin fell silent. Even the business-suit man stopped muttering. Everyone watched as this stranger cradled Derek’s daughter to her chest and began to hum—low and soft—a melody between a lullaby and a prayer. She swayed gently from side to side, eyes closed, lips moving like she was having a conversation with Rosie that no one else could hear.

And then, impossibly, Rosie stopped crying. Not gradually; all at once, as if someone flipped a switch. She let out one last shuddering sob, nestled her face into the woman’s neck, and went still. Derek watched in stunned disbelief as his daughter’s tiny fingers curled around a strand of dark hair, holding on like she’d found what she’d been searching for all along.

The woman opened her eyes and looked at Derek. For a long moment, neither spoke. Then, very quietly: “She just wanted to be held by someone who wasn’t afraid.”

Derek didn’t know what to say. He wasn’t sure there was anything to say. He sat there, watching a stranger rock his daughter to sleep, and wondered how she could know what Rosie needed when he—her father—had failed for three hours.

The flight attendant stopped mid-aisle, her rehearsed speech dying on her lips. She blinked, then retreated to the galley as if she’d witnessed something too intimate to interrupt. Passengers returned to books, phones, movies; tension drained from the cabin like air from a balloon.

“I’m Cassidy,” the woman said, settling into the empty seat beside Derek. Rosie, asleep, breathed slow and even against Cassidy’s collarbone. “And before you ask, no, I’m not some baby whisperer. I just remember what it feels like.”

“What what feels like?” Derek asked.

Cassidy’s eyes drifted to the window where the darkness showed the first hints of dawn. “Being so tired you can’t see straight. Feeling like everyone is watching you fail. Wondering if you’ll ever figure out how to do this.” She paused, her voice dropping to a whisper. “I spent the first year of my daughter’s life convinced I was the worst mother in the world. Turns out I was just the only one trying.”

Derek glanced at the little girl sleeping across the aisle. She had Cassidy’s dark hair, but a softer, rounder face—the peaceful expression only sleeping children can manage. “Her father?” he asked, then regretted it. “Sorry—that’s none of my business.”

“It’s fine,” Cassidy said, though her jaw tightened. “He left when Hazel was six months old. Said he wasn’t ready to be a dad. Funny how they figure that out after the hard part’s supposed to start getting easier.” A humorless laugh. “My mom was the only one who helped me. She moved in, took care of Hazel while I worked, held me together when I was falling apart.” Cassidy’s voice cracked. “She died last week. Heart attack. No warning. No goodbye. Just gone. This flight is us coming home from the funeral.”

Something shifted in Derek’s chest—recognition beyond sympathy. He knew that kind of loss. He lived with it daily. “I’m sorry,” he said, and meant it more than he’d meant anything in a long time. “My wife died giving birth to Rosie. She never got to hold her. Not really. Just once, for a few seconds, and then—” He couldn’t finish. He never could.

Cassidy turned, and for the first time he saw the full weight of exhaustion in her eyes. Not just long-flight tired or sleepless-night tired, but the exhaustion of carrying grief alone for so long you forget what it feels like to put it down. “So we’re both doing this by ourselves,” she said. It wasn’t a question.

“Yeah,” Derek said. “I guess we are.”

They sat in silence, watching the sky lighten. Rosie slept on, rising and falling with each breath—unaware of the two broken people holding her up. Across the aisle, Hazel stirred, mumbled about butterflies, and settled.

“She talked about you,” Cassidy said suddenly.

“Who?”

“Rosie. Well—not talked, obviously. But when I held her, she kept looking at you. Even when she was crying, she was looking at you—making sure you were still there.” Cassidy shifted Rosie; the baby sighed contentedly. “She’s not crying because you’re doing something wrong, Derek. She’s crying because she knows how hard you’re trying. Babies feel that—the fear, the love. All of it.”

Heat burned behind his eyes. He blinked fast, turned toward the window so Cassidy wouldn’t see. “My wife,” he said, voice rough. “She said something right before—right at the end. She said, ‘Find someone who loves her like you love me.’ I thought she was talking about Rosie—about finding someone to help raise her. But now, I think—” He stopped.

“Now you think what?” Cassidy asked gently.

“I don’t know,” he said. “I don’t know what I think anymore.”

The pilot crackled over the intercom: beginning descent into Seattle. Cabin lights flickered on. Passengers stirred, gathered belongings, prepared for landing. Across the aisle, Hazel’s eyes fluttered open; she sat up with the instant alertness only children possess. “Mommy,” she called, voice thick with sleep. Then she saw Derek and Rosie; her eyes went wide. “Mommy, there’s a baby.”

Cassidy smiled—the first real smile Derek had seen. “I know, sweetheart. This is Rosie, and this is her daddy, Derek.”

Hazel studied Derek with the serious intensity of a four-year-old making an important assessment. “Why is he sad?” she asked.

“He’s not sad, baby. He’s just tired like us.”

Hazel considered, then nodded, satisfied. “My grandma went to heaven,” she announced to Derek. “Mommy says she’s watching us from the clouds. Do you think she can see the plane?”

His throat tightened. “I think she can see everything,” he said. “I think she’s probably really proud of you—and your mommy.”

Hazel beamed. She pointed at Rosie, who was starting to stir in Cassidy’s arms. “Is the baby going to cry again?”

“I don’t think so,” Cassidy said, looking at Derek. “I think she found what she needed.”

The plane touched down with a gentle bump; chaos erupted—the usual deplaning ballet. People stood before the seatbelt sign went off, yanked bags from overheads, jostled for the aisle. Derek reached for Rosie; Cassidy handed her over carefully, fingers brushing in the transfer.

“Thank you,” he said. Inadequate, but all he had. “I don’t know how to—I mean, you didn’t have to.”

“I know,” Cassidy said, already gathering Hazel’s things, stuffing the rabbit back into a small backpack—efficient motions of a mother who’s done this a thousand times. “But I wanted to. And sometimes that’s enough.”

Hazel tugged Derek’s sleeve. “Are you coming to our house? I have toys. I can show the baby my toys.”

Derek looked to Cassidy, expecting a gentle redirection. Instead, she paused—hand on the seatback—and met his eyes. “I’m not ready,” she said quietly. “For whatever this is—whatever it could be. I just buried my mother, and I’m barely holding it together, and I don’t know if I can—”

“I understand,” Derek said quickly. “I wasn’t expecting—”

But Cassidy continued. “I work at Rosewood Cafe on Maple Street. Hazel and I are there most mornings. If you ever—if you ever want to—” She trailed off, then pulled a receipt from her bag, scribbled an address on the back, and handed it to him. “No pressure. No expectations. Just… if you want to.”

He folded the paper carefully and tucked it into his pocket. “Rosewood Cafe,” he repeated. “Maple Street.”

“Mommy makes the best hot chocolate,” Hazel added helpfully. “With extra marshmallows.”

The line moved. Cassidy picked up Hazel and stepped into the aisle, then turned back one last time. “She’s beautiful, Derek. Rosie—she’s really, really beautiful.” Cassidy’s voice caught. “And she’s lucky to have you—even if it doesn’t feel like that right now.”

Then she was gone, swept into the stream of passengers. Hazel’s sleepy face peered over her shoulder until they turned the corner and vanished. Derek stood for a long moment—Rosie warm and solid in his arms, the paper burning a hole in his pocket. The business-suit man pushed past with an impatient grunt. Derek barely noticed. He was thinking about Madison, her last words, the way Rosie stopped crying the moment a stranger held her. He was thinking about grief and exhaustion and the impossible weight of doing everything alone. He was thinking about a little girl who wanted to show Rosie her toys and a woman with tired eyes who remembered what it felt like.

The months that followed were endless and impossibly fast. Derek went back to work, back to daycare drop-offs and late-night feedings and weekend park trips where other parents smiled with that particular mix of pity and admiration reserved for single fathers. He got better at the practical things: bottle temperatures, sleep schedules, the art of grocery shopping with a baby strapped to his chest. But the loneliness didn’t fade. If anything, it deepened—settling into the quiet when Rosie slept and the apartment was too still, and Derek found himself staring at Madison’s photo on the mantle, wondering what she’d think of the father he was becoming.

He kept the receipt in his wallet. Some nights he’d take it out, tracing the handwritten letters with his thumb: Rosewood Cafe, Maple Street. Some mornings he’d put Rosie in her car seat and drive across town—telling himself he was just exploring. He’d park across the street from a small cafe with a green awning and flower boxes in the windows. He’d watch families come and go; couples share pastries; mothers meet for coffee while their children played.

He never went inside.

Eight months passed. Rosie learned to crawl, to pull herself up, to take her first wobbly steps into Derek’s arms. She learned to say dada and no and more—her vocabulary expanding weekly. She was becoming a person—a real person with preferences, opinions, and a laugh like bells. Derek loved her so fiercely that sometimes it hurt to breathe. But there were nights she’d cry inconsolably, and nothing Derek did could calm her. On those nights, he’d hold her and rock her and whisper the same words he’d whispered on the plane: “I’m sorry, baby. Daddy’s trying.” And sometimes, in the darkest hours, he’d think about a stranger who held his daughter for twenty minutes and did what he couldn’t do in twenty hours.

He thought about that night more than he wanted to admit. Cassidy’s tired eyes. Hazel’s serious questions. The way the cabin went silent when Rosie stopped crying. He thought about the way Cassidy said, She just wanted to be held by someone who wasn’t afraid—and wondered if she was right. He thought of her every time he passed a mother and daughter in the grocery store. Every time he saw a woman with dark hair in a messy ponytail. Every time Rosie reached for someone who wasn’t him.

On Rosie’s first birthday, Derek woke before dawn. He lay in bed, listening to her babble through the baby monitor, and made a decision. He got up, showered, dressed Rosie in her nicest outfit—a yellow dress with little daisies that Madison’s mother had sent—and drove across town to Maple Street.

The cafe was exactly as he remembered: green awning, flower boxes, a chalkboard sign with the daily special. Through the window he saw mismatched tables and chairs, local art on the walls, a cozy warmth that made you want to stay. And behind the counter was Cassidy. Her hair was longer, pulled into a loose braid. An apron dusted with flour. She was laughing at something the elderly man at the register said—her whole face transformed—and Derek’s heart did something strange and unfamiliar.

He almost turned around. He almost got back in the car, drove home, and convinced himself this was a stupid idea—that eight months was too long—that she wouldn’t remember him—that he was being ridiculous. But then Rosie made a sound. Not a cry, not a laugh—just a small, curious noise. Derek looked down at his daughter. “What do you think?” he asked. “Should we go in?” Rosie blinked at him with Madison’s eyes and said, very clearly, “More.”

Derek laughed—a real laugh he hadn’t heard from himself in months. “Okay,” he said. “Okay, Rosie. More it is.”

He pushed open the door. A small bell chimed; the smell of coffee and fresh bread washed over him. The cafe was half full with the morning crowd: laptops, couples, an older woman reading a newspaper. No one looked up—except one person. In the far corner by the window, a little girl with dark curls bent over a piece of paper, coloring intently, tongue poking out. An empty chair sat next to her, a stuffed rabbit propped against the back.

Derek recognized her immediately. Bigger now, older—but the same serious expression, the same careful crayon grip. Hazel looked up, as if sensing his gaze. Her eyes went wide. Then she shrieked, making every head turn. “Mommy! Mommy! It’s the airplane man! The airplane man with baby Rosie!”

Cassidy nearly dropped the coffee pot. She spun, scanning until her eyes found Derek by the door, Rosie in his arms, looking like he wasn’t sure whether to run or stay. For a long moment, no one moved. Then Rosie wiggled, pointed at Cassidy with a chubby finger, and made a sound Derek had never heard from her before.

“Ma,” she said. “Ma-ma.”

Derek felt the blood drain from his face. “Rosie, no, that’s not—”

But Cassidy was already moving. She set down the coffee pot, came around the counter, and walked toward them—tears streaming. Hazel jumped from her chair and ran too, her drawing forgotten, rabbit abandoned.

“You came,” Cassidy said, stopping a few feet away. Her voice shook. “I thought—I didn’t think—”

“I wasn’t going to,” Derek admitted. “I almost didn’t—about a hundred times. I almost didn’t.”

“Then why did you?”

Derek looked at Rosie, still reaching for Cassidy, still saying “Ma” like it was the most natural thing in the world. “Because she hasn’t stopped talking about you,” he said. “Not talking, obviously. But every night before she falls asleep, she makes this sound—this humming. It took me weeks to figure out where I’d heard it.” He swallowed. “It was the song you sang to her on the plane. She remembered.”

Cassidy’s hand flew to her mouth. “That was my mother’s lullaby,” she whispered. “She used to sing it to me when I was little. I didn’t even realize I was—”

“She remembered,” Derek said again. “And so did I.”

Hazel reached them, bouncing with excitement. “Is baby Rosie going to play with my toys now? I told her she could—remember, Mommy? I told her on the airplane.”

Cassidy laughed—a wet, wonderful sound—and bent to Hazel’s level. “I remember, sweetheart. Why don’t you show her the corner with the crayons? Rosie might like to draw.”

Hazel’s face lit up like Christmas. She looked at Derek, hopeful. “Can I hold her hand? Please? I’ll be really careful.”

Derek set Rosie down. She was steady now—walking for two months—though she still preferred to hold on to something: a table edge, a pant leg, a finger. She looked up at Hazel with wide, curious eyes.

“Hi, Rosie,” Hazel said solemnly, extending her small hand. “I’m Hazel. We’re going to be best friends.”

Rosie studied the hand—then reached and grabbed Hazel’s fingers. The two toddled off toward the corner table, Hazel chattering about crayons and coloring and the best way to draw a butterfly. Derek and Cassidy watched them go, standing close enough that their shoulders almost touched.

“She called you ‘mama,’” Cassidy said softly.

“I know. I’m sorry. She doesn’t really—”

“Don’t apologize.” Cassidy’s voice was firm, but something fragile, hopeful, and terrifying lived underneath. “My mother used to say children know things—things adults are too scared to see.” She turned to Derek. “Maybe she sees something we’re not ready to admit yet.”

The ground shifted under Derek’s feet. “What are you saying?”

“I’m saying that for eight months I’ve been thinking about a man on an airplane—a man terrified, exhausted, in over his head, but holding his daughter like she was the most precious thing in the universe. I’m saying I’ve been thinking about how he looked at me when I sang her to sleep—like I’d done something miraculous—when really I just remembered what it felt like to need help and be too proud to ask.” She stepped closer—close enough that he smelled coffee, flour, and maybe vanilla. “I’m saying Hazel asks about you every single day. She draws pictures of the airplane man and baby Rosie. She put them on her wall. And every time I see them, I wonder what would’ve happened if I’d been braver—if I’d given you my number instead of just an address, if I’d trusted that whatever I was feeling on that plane wasn’t just grief and exhaustion, but something real.”

“Cassidy—”

“I’m not done,” she said, crying harder now, voice steady. “My mother died never knowing if I would find someone. She used to say good men are the ones who stay. Not the ones who make promises. Not the ones who say the right things. The ones who stay—even when it’s hard, even when they’re scared, even when they don’t know what they’re doing. She said I’d know him because he’d already be doing the hard things alone.” She reached up and touched Derek’s face, her palm warm. “You stayed. For eight months you’ve been doing this alone, and you stayed—for your daughter, for Madison, for yourself. And now you’re here, and my daughter is teaching your daughter to draw butterflies, and I don’t know what happens next. But I know—”

“What do you know?” Derek asked, barely managing the words.

“I know that when you walked through that door, I finally understood what my mother meant about good men—about staying.” She smiled through tears. “I know I don’t want to do this alone anymore. And I don’t think you do either.”

Something broke open inside him—not a wound, but a wall. A wall he’d built eight months ago in a hospital room, brick by brick, every time someone told him he was doing great, every time someone said Madison would be proud, every time someone looked at him with pity and called him brave. He had built that wall to protect himself—to contain the grief—so no one could ever hurt him like losing Madison had. But standing in a tiny cafe on Maple Street with the woman who held his daughter on an airplane and sang a lullaby and remembered what it felt like—the wall didn’t seem so important anymore.

“I don’t know how to do this,” he said. His voice cracked. “I don’t know how to be. I don’t know if I can.”

“Neither do I,” Cassidy said. “But maybe we can figure it out together. One day at a time. One cup of coffee at a time.” She glanced at the corner where Hazel and Rosie were now both covered in crayon, giggling at something only they understood. “One butterfly drawing at a time.”

Derek followed her gaze, watching his daughter laugh with pure, uncomplicated joy. Rosie looked up, caught him watching, and waved—a clumsy full-arm wave that nearly knocked the crayon from Hazel’s hand. “Dada,” she called. “Dada, look.”

“I see, baby,” Derek called back. “I see.”

The elderly man behind the counter—the owner, as Derek would later learn, a man named George who’d known Cassidy’s mother for forty years—cleared his throat loudly. “Hey, Cass,” he called. “You gonna introduce me to your young man, or should I keep pretending I’m not watching this like my favorite soap opera?”

Cassidy laughed, wiping her eyes. “George, this is Derek. Derek, this is George. He’s going to give you a free coffee and a muffin because he’s a romantic and he’s been waiting for this moment since I told him about the airplane.”

George snorted. “I’m giving him free coffee because anyone who makes you smile like that deserves at least that much.” He looked at Derek with eyes that had seen a lot of years and stories. “Blueberry or chocolate chip?”

“Chocolate chip,” Derek said automatically.

“Good answer. Cass, take your break. I’ll handle the counter.”

Cassidy led Derek to a small table by the window—across from Hazel and Rosie, still creating their masterpiece. Morning sunlight streamed through the glass, catching dust motes, making everything look softer, more golden, than it had any right to be.

“This is where my mom used to sit,” Cassidy said, running her hand over the worn wood. “Every morning for twenty years she sat here with her tea and crossword. George keeps it reserved for her—even now. Old habits, he says.”

Derek looked at the empty chair across from him—and suddenly he understood. This wasn’t just a table. It was a shrine, a memory, a promise. A place where love had lived—and continued to live—even after the person was gone. “What was her name?” he asked.

“Ruth. Ruth Ellen Foster.” Cassidy smiled at the name; there was no sadness in it—just love, gratitude, the quiet peace of someone who had learned to carry grief without being crushed. “She would’ve liked you. She would’ve said you have honest eyes.”

“Do I?”

“The most honest I’ve ever seen.”

George appeared with two coffees and two enormous chocolate chip muffins. He set them down without comment, then retreated with a knowing wink.

“So,” Cassidy said, wrapping her hands around her mug. “What happens now?”

Derek looked at her—the woman who stepped into his life for twenty minutes on an airplane and somehow changed everything. He looked at the girls in the corner—already inseparable after ten minutes, heads bent together over a shared page. He looked at the empty chair where Ruth Ellen Foster used to sit, thought about Madison, thought about how grief and love are sometimes the same thing—just wearing different clothes.

“Now,” he said slowly, “I think I’d like to hear about Ruth. And maybe you’d like to hear about Madison. And maybe, if it’s okay with you, I’d like to come back tomorrow. And the next day. And the day after that—until those girls are so sick of each other they’re fighting over crayons instead of sharing them.”

Cassidy laughed—that wet, wonderful sound again. “That might take a while. Hazel’s pretty stubborn.”

“Good thing I’m not going anywhere.”

Outside, the sun kept rising. Inside, two broken people sat across from each other and began, slowly and carefully, to tell their stories. In the corner, a four-year-old and a one-year-old created a drawing that would later be framed and hung on a wall in a house that didn’t exist yet—a house with a green door, a backyard swing set, and a kitchen that always smelled like coffee and fresh bread.

But that was later. Right now, there was just this: two cups of coffee, two chocolate chip muffins, and the sound of children laughing. Right now, there was Cassidy’s hand reaching across the table and Derek’s hand meeting hers halfway, their fingers intertwining like they’d always been meant to fit. Right now, there was a single dad and a single mom—both tired, both scared—both hoping that maybe, just maybe, they wouldn’t have to do this alone anymore.

In the corner, Rosie looked up from her drawing, saw her father holding hands with the woman from the airplane, and smiled. It was a smile that looked exactly like Madison’s smile—the smile Derek had been so afraid of losing. He realized now he hadn’t lost it at all. He’d just been waiting for the right moment to see it again.

“Dada,” Rosie said, pointing at her drawing. “Look. Family.”

Derek looked at the paper—a chaotic mess of color that might have been four stick figures if you squinted. He looked at Hazel, nodding proudly. He looked at Cassidy, crying again—and smiling, too. “Yeah, Rosie,” he said, voice thick with something like hope. “Family.”

George watched from behind the counter, wiping the same spot he’d been wiping for ten minutes. He thought about Ruth Ellen Foster—how she sat at that table every morning and told him someday her Cassidy would find her person. “Took your time, didn’t you?” he murmured to the ceiling, to the clouds, to wherever Ruth was watching from. “But I guess you always did have a flair for the dramatic.”

Somewhere far above, on a plane crossing the same sky Derek and Cassidy had crossed eight months ago, a baby started crying. The mother looked around apologetically, bracing for judgmental stares. But the woman in the seat next to her just smiled and held out her arms. “May I?” she asked.

And the cycle continued. Strangers becoming helpers. Helpers becoming friends. Friends becoming family. One crying baby at a time. One act of unexpected kindness at a time. One moment of courage at a time. Because sometimes the unthinkable isn’t something terrible. Sometimes the unthinkable is simply this: a stranger who sees your struggle and chooses to help; a hand reaching out across an aisle; a lullaby remembered from childhood; a scrap of paper with an address scribbled on the back. Sometimes the unthinkable is love—arriving when you least expect it, in the form you least expect, from the person you’d never have thought to look for. And sometimes all it takes is a baby who won’t stop crying—and a single mother who does the unthinkable.
