Hallo Dr, my 1 year old boy is not picking up on weight, he weighs 8kg of which I ve been told it is very low for a one year old. I do try to feed him well but my concern is that after every feeding he poops, the food doesn t seem to stay in his stomach for proper digestion. Please advise, i am very much concerned about his weight. However, he is a very active boy and he has no fever at all.
