At the end of the eighth month, a baby can chew on things and reach for utensils when being fed. He turns his head away when he is finished eating, and he can roll all the way around. At this point, he might sleep between 11 and 13 hours a night and take two or three naps during the day. A seven month old can sit without any support and get on his hands and knees in the crawling position. You will be able to distinguish his cries because they are different according to his needs. He can babble happily and respond to his own name. He is learning about gravity by dropping things (and food) over the edge of his high chair. He reacts differently to different family members, and he shows some anxiety when he is removed from a parent.
