Hello,my son is 2.5 months old. When he was 1.5 months,he had accute diahherea with green loose motions along with blood and mucous. After the motion test,got to know that the reducing substance to be 1.5%. So doctor advised to switch to zero lac. Otherwise baby was on exclusive breast milk. After introducing zerolac,there is no problem as such. I read in one of the Internet pages that blood in stool is due to milk protein intolerance. Doctors says it s lactose intolerance. When I try to give him breast milk,the problem re occurred. Tried twice,with a gap of 15 days.but no luck. Is this due to milk protein intolerance or lactose? Will my baby develop resistance against this ? On breast milk he had gained weight vigorously. But now his weight gain is slow. Any alternative for zero lac. Also due to the tasteless powder,my son sometimes resists having milk. What can be done?

Hi... Greetings from Chennai. After going through your question in detail - this is my opinion and this is what I would have done if I were your treating pediatrician. Possibility -1. Cows milk protein allergy is a strong possibility as there as blood in the stool in exclusively breastfed baby. Suggestions -1. Mother should go off the cows milk products completely - including biscuits and chocolates and all products related to milk.2. Continue exclusive breastfeeding and if it is not sufficient you can opt for Zero lac.3. Cows milk protein intolerance in transient as it will go off as the kid grows up.4. Avoid all cows milk products till the kid is 1 year age.5. Mothers milk is the best for good growth of the baby. Rather than stopping mothers milk, it is best for the mother to avoid all milk products and continue breastfeeding. If you have any further queries you can approach me at the following link.
