What Are Developmental Milestones?

Developmental milestones are things most children can do by a certain age. They are not an exam — they are an observation map that helps parents understand their child's pace and helps providers spot when extra support may help.

This tool covers 12 CDC checkpoints from 2 months to 5 years across four domains: social/emotional, language/communication, cognitive, and physical/movement. It takes about 2 minutes to complete.

Note: A milestone checklist is not a substitute for standardized, validated developmental screening (e.g., ASQ). Use this tool for everyday observation and early awareness.

How to Use This Tracker

Select the checkpoint closest to your child's actual age.
For each item, mark whether your child "Can Do" it, is "Still Learning" it, or "Not Yet". "Still Learning" counts as half progress — it will not count the same as a missing skill.
After finishing all items, review the results. Red-flagged domains are worth discussing with a professional.

Data Source

All milestone items come from the U.S. Centers for Disease Control and Prevention (CDC) official developmental milestones pages "Learn the Signs. Act Early." (snapshot as of last review 2026-05-16).

This tool is for reference only and is not a substitute for validated developmental screening or a medical evaluation. If you have any concerns, please consult a pediatrician or child development professional.
