CDC’s milestones and parent tips have been updated and new checklist ages have been added (15 and 30 months). Due to COVID-19, updated photos and videos have been delayed but will be added back to this page in the future. For more information about the recent updates to CDC’s developmental milestones, please view the Pediatrics journal article describing the updates.
Skills such as taking a first step, smiling for the first time, and waving “bye bye” are called developmental milestones. Children reach milestones in how they play, learn, speak, act, and move (crawling, walking, etc.).
Milestones matter! Track your child’s milestones from age 2 months to 5 years with CDC’s easy-to-use illustrated checklists; get tips from CDC for encouraging your child’s development; and find out what to do if you are ever concerned about how your child is developing.
