Hi Welcome to the HCM I understand your concerns but don t worry. Occasional changes in poops of infants occurs commonly when we change to complementary feeds. You should be concerned about the colour and consistency if: 1. There is blood or mucous present which may occur when there is bacterial or parasitic infection of gut. It can also occur in some food allergies. 2. Very loose wastooland frequent stools suggestive of diarrhoea. 3. Persistent green coloured poops may be due to increased lactose or other sugars in the diet. 4. If child has fever along with the changes in poops with poor appetite. At present, I would recommend a proper complementary diet such as mashed fruits, porridge, boiled and mashed pulses, cereal based formulas for complementary feeds. Make sure you take a good care of hygiene. For any further questions, you may contact me.
