So our little guy has graduated to full-on solids (diced fruit/veggies, cheese, yogurt, Cheerios etc.) on the advice of his pedi. Trouble is, he takes the piece in his mouth, then gags, then throws up because of the gagging. Not pretty. He likes the little dissolving biscuits but of course gags on the last little bit. Does anyone have advice on teaching him how to deal with chunky food?
