A gentle, interactive tool
Developmental milestones, one age at a time
Pick your child's age and see the kinds of things many little ones are doing around then, plus a calm word on when it is worth checking in. Built from trusted CDC guidance, made for tired, loving parents.
The explorer
See what's typical, at your child's age.
Every child writes their own story, and their own timeline. This is a window, not a scorecard. Tap the milestones you already see at home if you like, and let it be a small, warm way to notice how far your child has come.
This is not a diagnosis. Children develop at their own pace, and reaching a milestone a little early or a little later is completely normal. This tool is only for learning and reassurance. If anything about your child's development gives you pause, the best next step is always a conversation with your child's doctor.

When it's worth checking in
Trust your instincts. You know your child better than anyone. If you have a concern at any age, or if your child loses a skill they used to have, talk with your child's doctor and ask about a developmental screening. You can also contact your state's free early intervention program yourself. Asking early is never an overreaction.
Questions families ask
Answers, in plain language.
Is this explorer a diagnosis or a developmental screening?
No. This tool is for learning and reassurance only. It shows the kinds of things many children do by a certain age, drawn from the CDC's "Learn the Signs. Act Early." milestone checklists, but it cannot evaluate your child.
Every child grows at their own pace. Only your child's doctor or a qualified professional can screen for or diagnose a developmental concern, so please bring any questions to them.
Where do these milestones come from?
They are based on the CDC's "Learn the Signs. Act Early." program, whose checklists were developed with the American Academy of Pediatrics. They describe skills that most children, about 75 percent or more, show by a given age.
We have summarized them in plain language and grouped them into four areas: social and emotional, language and communication, cognitive, and movement and physical development. For the full, official checklists, visit the CDC's website, which we link from the tool above.
My child has not reached some of these milestones. Should I worry?
A single milestone that has not arrived yet is often nothing to worry about, because children develop on their own timelines. Still, you know your child best, and it is always reasonable to check in.
The CDC's guidance is simple: if you have any concern, or if your child loses skills they once had, talk with your child's doctor and ask about developmental screening. Acting early opens doors to support, and asking is never an overreaction.
What does "act early" actually mean?
It means not waiting to see if a concern goes away on its own. If something about your child's development gives you pause, you can ask your child's doctor for a developmental screening, and you can contact your state's early intervention program directly, which is free and does not require a doctor's referral in most states.
Early support during the first years, when the brain is developing fastest, can make a lasting difference.
How do I get a free developmental evaluation for my child?
Every state offers early intervention for children under three, and public school districts evaluate children three and older, both at no cost to families. You can ask your child's doctor to refer you, or you can reach out to these programs yourself.
Your state's official early intervention and Parent Center resources will point you to the right contact where you live. The CDC's "Learn the Signs. Act Early." site is a good starting place for those links.
