What if my baby hasn’t hit a milestone?

Ranges are wide and every baby is different. If your child has missed several milestones for their age, or lost a skill, talk to your pediatrician.

Are these the official milestones?

They’re based on the CDC’s milestone guidance, simplified for a one-page checklist. The CDC has the full lists by age.

Can I track milestones in an app?

Yes. ParentFlow has age-by-age milestones with reminders, free, from pregnancy through age six.
