Reviewed against CDC checklists July 2026 · Clinical review by our founding clinical team pending — sources linked.
Part of The Fathom North Parent Guidebook. Everything entered here stays on this device unless the page clearly says otherwise.
Developmental milestones are things most children — 75% or more, by the CDC's definition — can do by a certain age. They are not a test, and this page will never score your child. Pick an age, look through the list at your own pace, and check anything you'd like to remember or bring up at your next appointment.
A note from us: checklists are conversation starters, not screenings. If anything here has been on your mind, mention it to your pediatrician — "wait and see" is not the only option.
Where to go from here
- Milestone items are from the CDC's Learn the Signs. Act Early. program — cdc.gov milestone checklists.
- Wondering what an evaluation actually involves? Start with our Wisconsin autism guide and the Wisconsin autism roadmap.
- Heading to an appointment? Print our evaluation prep checklist (PDF) and bring both lists with you.
That's the whole tool — it's here whenever you want to look again.
If the checklists left you with things you want to raise, the next tool turns where your family is right now into specific questions for those appointments.
