Typical Child Development Milestones - by Age

As a parent, it is helpful to understand when your child should be reaching their growth or developmental milestones. A child's development refers to your child’s growth and  physical, mental, emotional, and social changes. Their developmental milestones refer to when they acquire a new accomplishment in any of those categories, whether it is a first tooth or the first time your baby rolls over or speaks

It is important for parents to know that children reach their developmental milestones at their own pace. The developmental scale gives lots of room for children to reach their milestones. A child who is developing at a healthy rate may crawl at 5 months or at 9 months. Parents should not panic if their child has not reached their developmental milestones within the exact time frame listed.
