Hi, my dd said that her 'pee-pee' hurt this morning and when I had a look I found that she has a white discharge around her vagina, which seems quite red internally. The white discharge was sort of crusty and looked like fine sugar. (Sorry if too much information.) Is this thrush? I've heard of it but never had it myself. Should I take her to the doctor? I'd be grateful for any advice please because she's our only child and apart from dd I don't have much experience with children!! Thanks!!
