How can I get my 10-month old to eat baby food?

Choice: Given a choice, a child will get all their calories from what they like and not from what you think they should want. If you really think they need baby food, let them get hungry enough to want it, though if they prefer breast milk, there is no medical reason to make them stop.
Get messy! Most babies need to get their "hands dirty" when they feed! part of learning to eat solids is the texture and smells and new tastes. Give your baby a spoon to hold, or let him/her chew on a finger food while you feed baby food with the spoon. If your baby is refusing solids at ten months, check with your pediatrician.
