Rolling over, crawling, walking and talking are all considered milestones. Children reach milestones in how they play, learn, speak, act and move. Children reach milestones every day. Though all children develop at their own pace, most children reach developmental milestones at or about the same age. Children who do not reach milestones may need extra support and services to reach their full potential.
As children grow older, there are certain milestones that parents or caregivers can look for to know whether a child is developing normally. Keep in mind that developmental progress is not always steady. Changes in development may be observed during important life events like the birth of a new sibling. By tracking a child’s developmental milestones, over time there will be a greater understanding of the child's development and a better basis to know if there is a potential concern.
To see if a child two months to five years of age is meeting their developmental milestones, view the CDC’s Developmental Milestones checklist.
