My 3 year old daughter has had problems with her bm s for a long time now. For a few months she was taking lansoyl every day to help her stay regular but sometimes she would still get bloated and gassy. We stopped using that to try her and see how she would do. We thought she might be lactose intolerant and we tried lactose free milk and she did ok but to see if that was the problem we quit that milk and started her on whole milk but she got really bloated and gassy, and sometimes going 3 times a day and sometimes runny and sometimes solid, and leaving stains or little nuggets in her pullups. For 3 days she has been back on lactose free milk but her bm s are still runny and really stinky, although now it s only once a day. Does this sound like lactose intolerance or could it be something else?
