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

One and done
I wish there was a way to unmark because I’ve accidentally tapped on a milestone while scrolling. The thing that bothers me is that every time I open the app, it prompts to “add a child.” Due to health, fertility, & so on, I cannot have another even though I’ve always dreamed of 2. It’s just a reminder I can’t turn off/disable that constantly saddens me.
Nice idea poorly executed
As a mother of an infant, and as a family doctor, I like the concept of this app. However, in doctor language, the sensitivity of this app is too high and the specificity is too low. If a child is missing any of approximately 10 milestones at each age point, the app labels them as missing milestones and recurrently urges the parent to bring them in for evaluation. My typically developing infant has been labeled as missing milestones at each age cut off, and I suspect 90% of children would. Fortunately, as a doctor, I’m able to recognize that this is a failing of the app, rather than a failing of my child, but a mother without as much medical knowledge could be truly alarmed. It would be far more useful if it used a higher cut off for labeling a child as missing milestones, such as if a child missed multiple milestones at one age group, or was missing milestones of a younger age group. As it is, I would not recommend this to parents. The only reason I gave it two stars instead of one is that it is interesting to see what approximately your child should be learning at their age, as long as you know enough not worry if they are missing one or two skills.
Developer Response ,
Thank you for reviewing the app. We appreciate your comments and value the role healthcare providers play in helping children develop to their fullest potential. To help identify the one in six children with a developmental delay, the American Academy of Pediatrics recommends both developmental surveillance (monitoring) and screening as early as possible. The earlier developmental concerns are identified, the sooner children can connect with services and support, like early intervention, to help their development. Unfortunately, it is estimated that only 10% of eligible children receive early intervention services by age 2, and many children with delays and disabilities are not identified before kindergarten, often missing out on early services and supports. The app is intended to help parents, many of whom are not aware of typical developmental milestones, monitor their children’s development and communicate any potential concerns with their child’s healthcare provider. It is not a replacement for a standardized developmental screening tool (where sensitivity and specificity apply) but supports screening by informing parents of typical development and prompting them to contact their child’s doctor when there is a potential concern between recommended screening ages. The developmental milestones used in all of CDC’s materials, including this app, reflect milestones that most children would be expected to reach by the indicated ages. Any missing milestone should prompt a conversation with the child’s doctor and screening using a validated tool. Parents and providers working together, through regular developmental monitoring and screening as recommended, can help determine if a child’s development is on track. The app is a starting point towards helping children receive the support they may need.

Can use a few updates
I like this app so far. I’ve been using it for a few weeks and like how the information is populated for the child’s age. I do think they could use a minor update on how the milestones are tracked in correlation to the age you enter for your child. For instance my child is 22 months and I skipped ahead and checked off items for her in the 30 month old section and expected that it would tell me how she is tracking based on other children her age but instead it registered as she might be delayed because I didn’t check all the sections in the 30 month old section. It would be a nice addition if this feature was updated. Otherwise the app seems to work pretty well.
