<s>[INST] hi there, my 15 month old son has been having regular loose, sour smelling stools for the past couple of months. Hes otherwise really well, gaining weight, happy, playful and excellent appetite. He had a stool taken last week whicChatDoctore back all clear for any infections etc. The GP is not too concerned as he is happy and well. I have cut out cows milk and yogurts which seemed to make a slight difference. the runny/loose stools are not every time he has a bowel movement, but are quite regular and always sour smelling. Also hes been cutting his back teeth and now his incissors for past couple of months, could it just be because hes teething?Thank you in advance [/INST] I have gone through the details. Let me assure you that for a child of this age, passing stool a few times a day of somewhat loose consistency is absolutely normal, and you need not worry about it. Since the child is otherwise healthy, playful and gaining weight steadily, you need not be concerned. That is the reason your GP was not concerned. You have done a good thing by removing the milk from diet as it is optional anyway, but please include curd or yogurt as it is beneficial. Curd contains beneficial bacteria which will help in reducing the other bacteria of the gastrointestinal tract that are responsible for the foul smelling stools. Since the stool examination is otherwise ok, you need not worry about that too. However, you need not think that the stool odor would grossly improve. You need not worry about the grinding of teeth. It is normal too. </s>
