My son is very much active. But he left breastfeeding in 4 months. I give him cow milk since a month. Before he was given Lactogen milk. Now I try making him to eat but he eat. But he only eats egg maggi and upma. I tried givng him khichdi, fruits, pudding roti with milk etc. But he's not eating anything. i have even took him to paediatrician and he gave some medicines. But there is no change in his appetite. Please suggest.
