CDC’s Developmental Milestones
Is your baby’s or young child’s development on track for his or her age? Young
children grow so fast it can be hard to know what to expect. With the newly updated
FREE Milestone Tracker app from the Centers for Disease Control and Prevention
(CDC), you can learn how children play, learn, speak, act, and move as they grow
and how you can support your child’s development.
CDC’s FREE app for parents and care providers offers:
• Interactive milestone checklists in English and Spanish for children ages 2 months
through 5 years;
• The ability to adjust the checklist age if your child was born prematurely;
• Photos and videos that illustrate each milestone and make tracking them for your
child easy and fun;
• Your child’s milestone summary to share with others, like your child’s health care
provider;
• Tips and activities that can help your child’s development;
• Information on what to do if you have a concern about your child’s development;
• Reminders for appointments and developmental screening; and
• New milestone countdowns and custom user profiles

CDC also offers an Information for Families section that includes some additional topics such as:
