Baby milestone tracker
Check off social, language, movement, and cognitive milestones as your baby reaches them — month by month from 2 months to 2 years.
Frequently asked
At what age should my baby reach these milestones?
The tracker groups milestones into the CDC age checkpoints — 2, 4, 6, 9, 12, 15, 18 months, and 2 years. Most children reach a milestone within a range around these ages, not on an exact day.
What if my baby is behind on a milestone?
Milestones are guides, not pass/fail tests, and babies develop at their own pace. That said, if your baby misses several milestones for their age or loses skills they had, contact your pediatrician — acting early helps.
Is this a developmental screening?
No. This is an educational checklist based on public CDC milestone guidance. A formal developmental screening is done by your pediatrician with a validated tool.
