my 23 month old daughter has had diarrhea for 48 hours now. it started out as a runnu, mucousy dark yellow color. then within the past 24 hours, it has become a white to a cream color and is still runny and mucous like. she has no fever, still plays, but seems very tired with a loss of an appetite for food and drinks. she doesn't seem like her normal 'sick'. she seems great until she has her bowel movements and then seems very sick.
