What are some of the developmental milestones my child should reach by seven months of age?

From age four to seven months, the most important changes take place within your child. This is the period when he’ll learn to coordinate his emerging perceptive abilities (the use of senses like vision, touch,and hearing) and his increasing motor abilities to develop skills like grasping, rolling over, sitting up, and possibly even crawling.

Here are some other milestones to look for.

Developmental health watch

Because each baby develops in his own particular manner, it’s impossible to tell exactly when or how your child will perfect a given skill. The developmental milestones listed in this book will give you a general idea of the changes you can expect, but don’t be alarmed if your own baby’s development takes a slightly different course. Alert your pediatrician, however, if your baby displays any of the following signs of possible developmental delay for this age range.

• Seems very stiff, with tight muscles
• Seems very floppy, like a rag doll
• Head still flops back when body is pulled up to a sitting position
• Reaches with one hand only
• Refuses to cuddle
