Milestones matter! Encourage parents to track their child’s milestones from age 2 months to 5 years with CDC’s FREE Milestone Tracker app. Interactive checklists with photos and videos make tracking milestones easy and fun. The app generates a personalized summary to help you perform developmental surveillance as recommended by the AAP, offers parents tips for developmental promotion, and information about what to do if there’s a developmental concern. Visit cdc.gov/MilestoneTracker to print a free poster about the app to hang in your exam room!
