Hello there. I can understabd your concern. Since its a antibiotic associated diarrhoea, a pre and pro biotic supplement containing colustrum would be of great help. You get imubless sachets from the chemist and give one sachet as directed on the packet thrice a day. Also, you have to give this sachet before feeding the baby and there must be atleast 2 hours gap between advent and this. Feed the baby frequently. Consult a pediatrician in person if the loose stools do not stop. Best regards. Dr. Anil kumar jain.
