So A is just not into purees. I thought that he was getting there, but not so much. He will eat tastes of table food, that is softened, etc. (mashed potatoes, finely shredded cheese) and he manages them pretty well. What did you do, just give tastes and then when they got teeth, start offering more? I think that it is a texture thing, as I have tried Earth's Best and Plum Organics, and cereal...no go on really anything.
Re: Babies who didn't like purees
While I don't "get" BLW (why the rush to push eating adult table food), if they won't eat purees I would either wait a bit and try again or go the BLW route.
FWIW, they don't need teeth to eat. You only use your front teeth to bite things into smaller pieces. If you offer them small pieces they will use their hard gums to mash. If one waited until a child had molars to chew they wouldn't be eating solid food until after 1 year!
