Today my 2.5-yo dd has been complaining of a sore bottom (bright red genital area), "belly issues" (i.e. intestinal), and a sore mouth (indicating insides of cheeks, though no visible sores), all at once. The first two are problems she's mentioned on and off for some time. Could this be a candida problem, even though I don't have it and dd eats a lot of yoghurt?
