Every CDC milestone, 2 months to 5 years

The CDC's milestone checklists in one table, word for word, to read, print or download.

This table lists all 159 milestones on the CDC's “Learn the Signs. Act Early.” checklists, from 2 months to 5 years, word for word and grouped by the CDC's four domains. Each one is something most children (75% or more) can do by that age, so many do it sooner. Print it, or download it as a CSV file.

How to use it

The CDC says its checklists are tools for conversations with your child's doctor, and that its milestones “should not be used as screening or diagnostic tools to detect developmental delays.” If your child isn't doing one or more things on the list for their age, has lost a skill, or you're worried, the CDC's advice is to talk with your child's doctor and ask about developmental screening. Don't wait.

About the data

The CSV has one row per milestone: the age in months, the CDC's age label, the domain, the milestone in the CDC's words, the CDC page it comes from, that page's date and the date we checked it. The milestones are US government work from the CDC; please credit the CDC when you use them. Crawling isn't on any checklist; the 2022 revision lists only milestones most children (75% or more) reach by each age.
