When my first baby was tiny, I used to sing Blackbird into his ear — soft and slow, McCartney and me on the 2 a.m. shift together.
I wasn’t doing it to build his brain. I was doing it because it worked. But here’s what I’ve learned since, both as a music educator and as a mom who’s now done that shift twice: something real was happening in those moments. Not metaphorically. Measurably.
So this post is for the parent wondering whether “music stuff” this early actually does anything — or whether it’s just adorable noise. Short answer: it’s doing more than almost anything else you could pick. Longer answer below.
Your voice was their first instrument
Researchers at Harvard’s Music Lab have spent years studying what singing does to babies, and the findings are the kind that make you look at bedtime differently.
Infants listen to singing roughly twice as long as they listen to speech. Babies as young as five months old can remember a melody — and recognize it eight months later, which in baby time is basically a lifetime. And here’s my favorite part: researchers believe singing works on babies the way it does because it’s an unmistakable signal that says a familiar grown-up is paying attention to me. Not background noise. Not a screen. A person, close, focused entirely on them.
Which means you — off-key, exhausted, improvising verses about socks — are delivering something no app or playlist can. The song matters less than the singer. It always has.
It looks like play because it is play — and play is the curriculum
Here’s where I want to gently push back on a thing our culture believes: that play is the break from learning. For little ones, play is the learning. There is no other channel. And musical play happens to be one of the densest kinds there is.
Watch a one-year-old with an egg shaker. To us: adorable chaos. To her: a physics lab. I move my arm, the world makes a sound. I move it harder, the sound gets bigger. I stop — silence. I did that. That’s cause and effect being wired in real time, and it’s the foundation every later kind of learning stands on.
It goes further than you’d guess. Passing a shaker from one hand to the other, or reaching a rhythm stick across the body, builds what developmental folks call crossing the midline — a skill that sounds obscure and turns out to matter enormously for reading and writing later. Learning to tell sounds apart — loud from soft, fast from slow, the shaker from the drum — is literally pre-reading work; it’s the same ear that will one day separate the sounds inside words. Bouncing and swaying to a beat builds body awareness and balance. None of it looks like a lesson. All of it is one.
The part that doesn’t show up on a development chart
Music also does quieter work in little ones — the emotional kind.
Songs are how toddlers first practice big feelings safely. A slow song can downshift a revved-up nervous system (yours too — you’ve used the car playlist that way, don’t lie). The repetition little kids demand — again! again! — isn’t a rut; it’s how they build the deep comfort of mastery, the feeling of I know what comes next, and I can do it. That “I made that happen” moment with the shaker isn’t just physics. It’s one of a child’s first experiences of being capable — and stacking those small moments is how self-belief actually gets built at this age. Not praise. Evidence.
And then there’s the part I care most about: music is something you do together. Not something they perform while you watch — something you’re both inside of. A kitchen dance party, a family playlist that becomes the sound of this exact season of your lives, a song that belongs to the two of you. Kids whose homes are full of shared music aren’t just developing faster ears. They’re collecting proof that being together feels good. That’s the real deposit, and it compounds.
If you want more of this (with backup)
Everything above happens at home, free, starting tonight. And — if you want a room built for it, we have two doors, and they’re different on purpose:
Music Minis is our parent-and-little class — for the grown-up who wants to be in the experience, not watching from a chair. You’re in the band too.
Music for Littles is one-on-one time with a teacher for young kids who are ready to explore instruments with a guide of their own — no pressure to pick one yet, because they’re not too young for music, just too young for one instrument.
Either way — and even if it’s neither, and it’s just you and Blackbird at 2 a.m. — the music is already working.
