Aiyoh, I know how stressful it is when baby constipated and won't eat! A few of us mums tried adding pureed prunes or pumpkin into their meals, very gentle and usually works within a day or two, and also make sure baby is drinking enough water or milk, sometimes dehydration makes it worse. Since doctor sudah check and give medicine, the food should help speed things up, so hang in there! Normally once the bowel moves, appetite comes back lah, jangan worry too much.
