Recently I’ve seen a number of parents posting questions about whether their child is developmentally delayed or potentially autistic. This is certainly an upsetting prospect for any parent.
It can be very helpful to know the developmental milestones a child should be reaching at different ages. Although children develop at various rates, they all should reach certain milestones in how they play, learn, speak and act. There is great information about developmental milestones on the Centers for Disease Control and Prevention website.
This site has separate pages listing developmental milestones for 3 months, 7 months, and 1 – 5 years old (click links along the righthand side). Each age lists appropriate behaviors for social, emotional, cognitive, language and movement along with behaviors that may warn of a problem. If you suspect your child may have a problem, it's important to see a pediatrician to help rule out anything serious or to develop an appropriate intervention.
