Why kids repeat songs their parent sings, and what it means for their development
Last Tuesday, I dragged myself home from a 12-hour shift at the hospital, dumped my scrub bag by the door, and collapsed onto the living room couch with a heating pad for the tension migraine I’d had since 7 a.m. The laundry I’d thrown in that morning was still in the dryer, and dinner was just pizza dad had picked up on his way home from work. I was half-asleep when I felt two small bodies press up against either side of my legs. I opened one eye, expecting a request for extra gummy snacks or 10 more minutes of Bluey before bed. Instead, they took a deep breath in unison and started singing.
It wasn’t a song I knew by heart. It was the silly made-up one my husband had come up with when our oldest was a toddler, about a sock-eating monster that lives under the crib and loves stinky gym socks more than any snack. He’s always mispronounced “avocado” (his made-up verse goes “he eats socks and chips and a-vah-cah-doe”) and the kids got the mistake exactly right. They pulled me off the heating pad to hold their hands, bouncing on their tiptoes as they sang the chorus twice, just like dad does. By the end of the second chorus, I was crying. Not big, heaving sobs, just quiet tears that soaked the front of my old college sweatshirt. The kids stopped immediately, confused. My 4-year-old dug a half-chewed gummy bear out of her sweatpants pocket and held it up to my face, like that would fix it.
Dad leaned in from the kitchen doorway, grinning, and told me they’d been practicing for three days, hiding in their bedroom after bedtime to get it right just for me. That’s when the guilt I’d been carrying around for months bubbled up a little, right through the tears. For the past year, I’ve worked three night shifts a week, which means I miss almost half of all bedtimes. I’ve read all the parenting takes on how consistent bedtime routines from the same caregiver help kids feel secure, and I’ve spent so many 10-minute breaks at work scrolling through posts that make me feel like I’m failing at the one routine that matters most. I’d started planning big weekend trips to “make up for it,” buying extra special toys to bring home after my shifts, convinced I needed to overcompensate for the time I wasn’t there.
But standing there, wiping my eyes on my sleeve and listening to my kids repeat every silly line and wrong pronunciation of dad’s song, I started thinking differently about what connection actually looks like for kids. For a long time, I thought I had to be the one doing the routine to build that connection. But what I didn’t expect was that kids don’t just receive those small daily moments—they carry them with them, and pass them on, to the people they love.
Developmentally, that makes a lot of sense. Kids learn language and social connection through imitation, and repetitive small interactions stick with them far more than one-off big outings. When a kid repeats a song, a phrase, or a silly habit their caregiver does, that’s them practicing what they’ve learned about love and routine. It’s not a sign that they only connect with that one caregiver—it’s a sign that they feel secure enough in that routine to share it with someone else.
That’s a shift that’s helped me stop beating myself up, and it’s led to a few small, low-effort changes that I think other parents or teachers can use too. If you’re a parent who regularly misses daily routines because of work, illness, or co-parenting across two households, you don’t need to plan big expensive trips to catch up. Just ask the other caregiver to text you one small silly detail every week: a new made-up word, a wrong line from a song, an inside joke the kids have. You don’t need to memorize anything—just drop the line into a conversation with your kid next time you see them. Last week, I dropped dad’s mispronounced avocado line into dinner conversation, and both kids screamed so loud the dog ran under the table, they were so excited I knew their joke. That took 10 seconds, and it meant more than any toy I’ve ever brought home.
For teachers, especially preschool and kindergarten teachers, this works in the classroom too. Try adding a 2-minute “family song share” to circle time once a week. You don’t need any instruments or preparation—just ask a kid to share the song their mom or dad sings them at bedtime, even if it’s made up and half the words don’t make sense. It helps you understand how kids experience connection at home, and it gives kids a chance to bring a little piece of their family into the classroom, which builds confidence far more than a lot of planned lessons.
I still don’t know all the words to the sock monster song. I still miss half the bedtimes, and I still have days where I feel that familiar twinge of guilt. I still haven’t followed through on any of those big weekend trips I planned to “make up” for my missed nights. Last week, when I got home from a night shift at 7 a.m., I found a crumpled piece of construction paper on my pillow. It had the words to the chorus scribbled in my 6-year-old’s wobbly handwriting, half the letters reversed, and a sparkly unicorn sticker stuck in the corner. It’s taped to my work locker now, right next to my ID badge.
I don’t think we’ll ever have the perfectly consistent bedtime routine all the parenting articles talk about. But that’s okay. We have the wrong-pronounced avocados, the crumpled notes, and the silly songs the kids carry back and forth between us. That’s enough, for now.
