If your baby has had liquid stools for a week but they are not more frequent and she does not seem to be in pain, there are a few things you can do. It is important to make sure she stays hydrated and to prevent irritation on her skin, you can apply zinc cream to her bottom at each diaper change. Keep an eye on the color of her urine and check if her lips are hydrated. If the diarrhea persists for another week or if she develops a fever, it would be wise to consult a doctor.
