Hi. My baby is 4yrs old. Taking iron[tonoferon] n multivitamin[glutanase] and osto-polibian syrups. I observed often foul smelling stool, color vary from green, dark green n sometimes dull black clay balls noncticky and sometimes sticky stool with normal brown color. I am worried. She doesn't eat food properly. Nor drink milk. Usually poops twice a day. One immediately after lunch. When she was born. Kept in icu for 4 days from 11th day of birth. As her billrubin count was very high and delivary doctor did not paid much attention:(. After 3 days in icu under some lightig treatment. Baby is good. Sometimes I feel some popping sound in he knees when I touch them. Can you please suggest in this regard also.
