#AskTheExpert 10 days back my 3m old baby had motions and saw some blood on motion. she is full on formula milk lactogen. so doctor suggested some antibiotics and powder changed to zerolac. after 4 days motions controlled so we stopped using zerolac and switched to similac as doctor suggested as lactogen having high amount of lactose . after 3 days again i saw some streak of blood on her motion and she is pooping 4 tymes daily. so again switched to zerolac currently using. what should I do now. I hv fear and doubt that if again I switched to normal powder she would get motions. pls ans my question
