<s>[INST] My Son is 3 weeks plus and ahas been using Lactogen 1 as the mother breast feeding do not suffice. Bust for the past few day he has been having a loose stool after having been given Lactogen 1 though this is not the case when breast fed normally. What may be the cause ? What is the alternative bearing in mind that the mothers milk is not sufficient ? Thanks, Chris [/INST] Breast milk is the best milk for baby. Usually mother milk is sufficient for the baby, its is just about building in yourself that you can feed your baby well and the milk output will be fine. If milk is prepared hygienically lactose 1 per se does not cause diarrhea. Try to prepare the milk more hygienically with the proper dilution. Otherwise you can use full cream milk without dilution. I hope this satisfies you </s>
