Do Early Childhood Milestones Predict How Your Child Turns Out Later?
Last Tuesday I was digging through the hall closet for a puffy sleeping bag for my 16-year-old’s weekend camping trip, and came across the tattered blue baby book my mom gave me right before my oldest was born. The pages are smudged with old coffee and a faint stain of applesauce, and every two-month well visit is marked up in my messy handwriting: rolled over at 3 months, sat unassisted at 6, took first steps at 10, first full sentence (“more cookie”) at 12 months. When I flipped to the back section for my younger daughter, Lila, the entries are sparser, and the dates are all months later: rolled at 5, sat at 8, first steps two weeks after her first birthday, first word (“dog”) at 18 months.
I remember sitting in the pediatrician’s exam room at 18 months, filling out that clipboard questionnaire, my hand shaking as I checked “no” next to “says 3 or more words besides mama/dada.” I left the office crying into my steering wheel in the parking lot, ate a whole pack of cheese crackers I kept in the glove box, and that night ordered a $40 “late talker intervention activity kit” from an Instagram ad. I spent two weeks doing the flashcard drills every afternoon, convinced Lila’s slow start would turn into years of struggles.
Fifteen years later, that’s hard to reconcile with the girl who’s currently sitting at our kitchen table quizzing herself on debate team case law, who aces her honors algebra tests without staying up late to study, who remembers that my coffee order is an oat milk latte with one sugar even when I forget to tell her. My oldest, Sam, who hit every milestone a full two months before the chart said he should? He’s the kid who forgets his own lunch three times a week, who spends every free minute drawing graphic novels in his notebook instead of studying for history, who still hasn’t decided if he even wants to go to college. The early milestones I obsessed over didn’t just fail to predict their strengths—they almost predicted the opposite.
I talked about this a couple years ago with my neighbor, Jen, who’s a pediatric speech-language pathologist with 22 years working in public schools. She told me most parents misinterpret what milestones are for. Milestones are just averages, she said, collected from thousands of kids to give doctors a rough starting point for check-ins. They’re not a test you pass or fail, and they’re definitely not a crystal ball for who your kid will be as a teenager or adult. The only time a late milestone matters is when it’s part of a pattern of other concerns, not a single outlier.
She gave me three concrete things to tell other parents who are panicking like I was, and they’ve stuck with me. First, when you’re going through a milestone checklist, look for clusters of missed markers, not one. If your kid walks two months late but points to ask for things, makes eye contact, plays pretend, and babbles constantly, that’s just your kid’s timeline. If they’re not interacting with you at all, or missing three or more major milestones across different areas, that’s when you bring it up to a doctor. Second, if you’re worried about speech delay, skip the fancy kits and do three small things every day: narrate what you’re doing without quizzing them (instead of asking “what’s this?” every time you pass a car, just say “that’s a red fire truck, it’s going to the station”) turn off background TV when you’re in the room with them, and get on the floor to play with their favorite toy for 5 minutes a day without your phone. Third, don’t compare your kid to your friend’s kid, or your older kid, or any kid on social media. If you catch yourself deep in a rabbit hole of milestone reels, close the app and go get a glass of water—your kid’s timeline is their own.
I still see new parents posting about their baby hitting a 3-month milestone early, like it’s a guarantee they’ll be a genius later, or panicking because their 12-month-old isn’t walking yet. I want to tell them what I’ve learned, but I also get it—when you’re a new parent, the only measuring stick you have is those little checkmarks on a piece of paper. No one gives you a manual that says every kid develops in a different order, that early walking doesn’t mean you’re athletic, that early talking doesn’t mean you’re a good communicator, that late talking doesn’t mean you have a learning disability.
Sam was reading whole chapter books at 4, and his preschool teacher told me he was gifted and would probably end up with a top scholarship one day. We had so many meetings in elementary school because he refused to do written homework, he’d just draw instead. He’s never going to get that top scholarship, probably, but his graphic novel about a teen ghost hunter got selected for the local library’s teen art show this spring, and he sells prints at the local farmers market on Saturdays that people actually buy. Lila, the late talker I cried over in the pediatrician parking lot, just got accepted to a statewide debate camp this summer, and she volunteers twice a week tutoring middle school kids in math.
We don’t know how either of them will turn out long term. They’re still kids, still changing. But I know that those early checkmarks I spent so many hours worrying about didn’t tell me half of what I needed to know about who they would become. Milestones are just a check-in, not a forecast. Some of us just take a little longer to find our stride, and some of us start early but take our time getting where we’re going. Right now, that’s enough for me.
