for the last one week my 7 month son face is turning red (He is pushing hard) while passing stool. Stool is dry, having very strong-smell and in the form of black colour pellets. also, the quantity of stool is decreased. he is usually passing stool once in a day, but sometimes twice a day. In his food, he is taking nestum rice, naan, small banana, vegetable soup (carrot, peas, cauliflower) in day time while in night mother is feeding him. whether he is suffering from constipation?
