About this app

Milestones matter! Track your child’s milestones from age 2 months to 5 years with CDC’s easy-to-use checklists; get tips from CDC to support your child’s development; and find out what to do if you ever have concerns about your child's development.

From birth to age 5, your child should reach milestones in how he or she plays, learns, speaks, acts and moves. Photos and videos in this app illustrate each milestone and make tracking them for your child easy and fun! Spanish photos and videos are coming soon!

• Add a Child – enter personalized information about your child or multiple children
• Milestone Tracker – track your child’s development by looking for important milestones using an interactive checklist
• Milestone Photos and Videos – know what each milestone looks like so that you can better identify them in your own child.
o Due to COVID-19, photos and videos to support the updated milestones have been delayed for the Spanish checklists but will be added in a future update.
• Tips and Activities – support your child’s development at every age
• When to Act Early – know when it’s time to “act early” and talk with your child’s doctor about developmental concerns
• Appointments – keep track of your child’s doctors’ appointments and get reminders about recommended developmental screenings
• Milestone Summary – get a summary of your child’s milestones to view, and share with or email to your child’s doctor and other important care providers

For more information and free tools to help you track your child’s milestones, visit www.cdc.gov/ActEarly.

*This milestone checklist is not a substitute for a standardized, validated developmental screening tool. These developmental milestones show what most children (75% or more) can do by each age. Subject matter experts selected these milestones based on available data and expert consensus.

CDC does not collect or share any personal information that can be used to identify you or your child.

The app was very useful and helpful when I was able to use it. I learned however, when I got a new phone, that it must have not setup an account for me, or rather, it seems to not use accounts, period. When I opened the app on my new phone there was nowhere to log-on. It was promoting me to start from scratch. So it appears I have lost data I had tracked about my baby and all my notes etc.

I have been utilizing this application for approximately two years to monitor my son's developmental milestones, and it was previously an exceptional tool. However, I am encountering a technical issue where the application immediately crashes upon opening, preventing its proper loading. Despite multiple attempts to uninstall and reinstall the application, the problem persists.

Downloaded this to use with and test for my clients' parents. The app won't even open without immediately crashing after reinstalling it multiple times and double-checking device settings and updates, so I definitely can't recommend it to the families I work with since it's unusable for me. On a Google Pixel 8 Pro if that makes any difference.
