My baby is 13months old. She has been passing motion 4times a day and this is continuing from past 1week. Her motion is not watery or loose. Its normal consistancy. We have done regular and culture stool examination. Everything seems normal. There is no sign of any bacteria from her stool culture. She does not eat any oily food nor any non veg. We give her probiotics(yogurt or curd) rice dal,nothing else. She is not eating anything else this days. Her activity is very good. She is playing well. She is not lactose intolerant. Please suggest any diagnosis or cure. What is the reason for such condition.
