Hi my son who is 4 years and 4 months old weights 14.7 kg with height of 98 cms. He have some serious issue while eating food. His diet is very less compared to other children's but he is active. Now his mother is worried about his height and weight as he very skinny. He doesn't like to go washroom and poops after 3 or days and dat too we have to forcefully push him to the washroom. He doesn't have any constipation problem but don't want to go. We feed him pediasure so complete his nutrition no affective at all and feeding him since long. So please advice some good protein powder and also some medication to increase his hunger so that he can gain some weight. Also some medication so he can poops everyday with any control so that he cannot hold back.
