Okay my little guy has done great with the puree baby foods and rice cereal. He loves them all. But I've now tried giving him like real food (puffs, crackers, teething wafers, banana etc.) And he like refuses to eat anything that's actually solid. He sometimes will take one little bite then gag and after that he's done. Idk how to get him to like real food! I try and eat a bite to show him how and he just has no interest. He clenches his lips shut and turns his nose up at it.. Help! How can I help interest him in it?
