I don't think you'll have much luck curing thrush with Moo Goo. If it is thrush, get onto it quick because it's irritating as hell. I would personally use a sposie, but with a cloth liner but I'm a little paranoid about stuffing up my nappies Hope it's all clear very soon.

Oh, also, I have heard of good quality, natural yoghurt being used for vaginal thrush, but never anything about baby bottom thrush. If you want to try more natural things than the thrush cream. A google would tell you more.
