Hi...for a 3 month old baby it is very unusual to have blood in the stools due to an infective cause if the baby is exclusively breast fed. If the baby is formula fed and bottle is used then it is possible that it could be an infective diarrhea and antibiotic like Taxim-O might work. If not then the other possibility is cows milk protein intolerance. Antibiotics like Taxim-O will not help in curing this. I feel that your baby is having cow s milk protein allergy. Unusually babies grow out of this sort of allergy by 1 year of age. My suggestions for you - 1. Mother should go off cow s milk protein completely. This means that you should avoid consumption of anything and everything related to cow s milk - like - milk/ curds/ ghee/ butter milk/ chocolates/ biscuits/ ice creams etc. Even while buying commercial food products, you need to see the ingredients and if they contain milk - do not consume them. 2. Feed you baby only exclusive breast feeds till 6 months of age and then start rice based feeds. 3. If this is followed scrupulously - the baby will stop having diarrhoea in another 3-4 days and then start gaining weight too. 4. If you feel your feeds alone are inadequate for the baby, then Zerolac is the only option till 6 months age. I request you to keep me posted about the recovery of the baby and follow of the case.
