Hello.. my 10 months old baby passing black pebble like stool from last 3 days. First I thought it's because of ragi porridge and also i hv added small piece of beetroot in his vegetable puree. But also today he passed the same stool; as yesterday he didn't have any dark coloured food. Is that fine or should I get his stool tested? He's active and eating well. He usually takes 3meals and a snack(fruits) and 500ml to 650ml of milk. I prefer giving him food prepared by me. From last 3 months he is on formula feed(nan pro 2).
