Re: weaning and introducing solids
At seven months it's usually recommended to nurse before offering solids, so you know he is filling up on the most nutritious substance. Then offer solids and if he doesn't eat much or isn't interested in eating at all (both of which are perfectly normal for babies that age), you don't have to worry about whether he's eating enough because you know he's getting plenty of breast milk.
