My son is 8 months old. After consulting my doctor, I started giving cow-milk to him when he was 7months old. I made a habit to feed him with spoon a d bowl. Now I stated using glass. He drinks with glass but not having as he had earlier. He starts crying looking at the glass only and if I try to feed by spoon he will have it with lil Natak... What should I do in this situation? Shall I add some fruit or nuts to try on it? Or any other alternative I should try? Please suggest me.
