My son will turn one next week and still will not eat lumpy food. I can not get past the heinz 4 month baby food (refuses my cooking). He gags and vomits whenever I try even the slighest texture. He also has the added complication of being allergic to egg and dairy. He is not interested in finger food at all nor feeding himself with a spoon. I took him to the pediatrician who said there is no physical reason for his gagging. I would really appreciate any suggestions.
