You can try potato, tomato, pork ribs soup. Let him try a few mouthfuls. If ok, add some rice if you like. This soup is very appetising. My son can finish the whole pot of potato, which is good source of carbo. he is 20mths, sometimes he can go without food. Dont even want to open his golden mouth. And he is underweight. So sometimes try to him him avocado. So tiring just to make him eat, not even considering the preparatn time. So stressed. Anyway, jia you.
