Recently we have started finger foods, but my son doesn't seem to have any interest in it. When I place a couple of things (cereal or whatever) on his tray all he does is pick it up and throw it on the floor. This has been a big game lately whether he's in a stroller or wherever. He has put some pieces in his mouth sometimes, simply to just spit it out again...or if he does manage to get it into the back of his mouth he gags on it. Sometimes he just squishes the food in his hands and that's about it. Is this typical of a child who is starting finger foods? If so, are there any tips or things I can do to make this more successful? Or is it just something he needs to do?
