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.

It does exactly what I need it to do. Tracks my children's milestones. Not sure why there are so many bad reviews. Personally I haven't had any issues with it. Looks like there was a technical issue after an update and instead of emailing the developers, people decided to leave a negative review and leave it up forever even after the issue was fixed. Don't be like these people. If an app is having issues, email the developer so they can fix it.

Was looking forward to using this, the day my baby turned two months, it started crashing. I never even really got to use it, because it is for 2 months and up. Go figure. Looking at the other reviews, I'm definitely not alone. It seems like y'all need to fix the updates.. until then the app is completely useless, as it won't even open.

Poorly made app that offers no backup. Once you switch your phone, all progress is lost. The purpose of the app is to track milestones but it can be so much more. Perhaps, try some user acceptance testing before publishing an app. The design and tracking of the app could use some updates. Also, you guys deleted your videos on Youtube so there is no longer a reference to those specific activites.

Thank you for your feedback. We conduct user testing with parents before each update. The current videos have been removed due to an update to the milestones. We will be launching an app update to reflect the newly released milestones in the coming weeks.
