In English and Spanish | Useful to Parent Centers, family-focused organizations, and families for observing and tracking the development of young children.
The Centers for Disease Control and Prevention (CDC) maintain a free online library of photos and videos that capture the milestones of development that young children might be expected to achieve at various ages–skills such as taking a first step, smiling for the first time, and waving “bye bye.” Children reach milestones in how they play, learn, speak, act, and move (crawling, walking, etc.). At CDC’s Milestones in Action site, parents of young children can:
- read fact sheets about development milestones for children;
- download age-specific checklists;
- keep track of their child’s development using the Milestone Tracker App (downloadable to mobile phone); and
- watch videos and photos that illustrate what each of the milestones looks like.

These resources are offered as part of CDC’s Act Early campaign, which focuses on identifying young children with developmental delays or disabilities. Developmental disabilities are a group of conditions due to an impairment in physical, learning, language, or behavior areas. About 1 in 6 children in the U.S. have one or more developmental disabilities or other developmental delays. It’s very important to identify these and act early to address whatever delay(s) each child is experiencing.
