My grand daughter aged four years now, underwent surgery for total colonic agangliosis Though she maintained average weight for the last three years, she has been losing weight which is a serious concern for us. Very often she falls I'll. She has Cow Milk allergy. Could you suggest some remedy to help gain weight. She now weighs just about 10.5 kg. Otherwise active, her digestive system goes for a toss every time she has anything other than curd rice. So,Could I also be suggested a suitable dietician or nutritionist keeping her health condition in view. Thanks.
