My bub is 3 months old fully formula fed has been on same formula since 1 week old with no issues. Last 2 days she has had really runny poo usually not long after a bottle. She is otherwise healthy, happy sleeping well not too hungry and her soft spot is not sunken at all. Problem is she is getting red in the nappy area from all the runny poo. Going to Dr on Monday all tho he is usually useless with the kids only Dr I can see. Anyway someone suggested it maybe lactose and try soy formula well she flat out refuses to drink soy!!!!
Any suggestions on the cause/solutions? Just looking for advise till I can see Dr Monday thanks
