Stages of Development

Developmental milestones are behaviors or physical skills seen in infants and children as they grow and develop. Rolling over, crawling, walking, and talking are all considered milestones. The milestones are different for each age range.

There is a normal range in which a child may reach each milestone. For example, walking may begin as early as 8 months in some children. Others walk as late as 18 months and it is still considered normal.

If you are having concerns about your child’s development and/or have noticed any red flags please feel free to call (559) 228-9100 (option 2) to set up a free consultation and to find out more about how occupational therapy can help your child.

Research has shown that the sooner developmental services are started, the better the outcome.
