I am absolutly diligent about ds2's nappies. They are disposables, I change them every 3 hours and he doesn't wee much.
It seems to be recurrant thrush, and have been given canesten HC, which I use 3 times a day, and it's not shifting it. It clears up for 2 days, they he'll poo in his sleep or something, and it's back, red raw and bleeding, and it takes a week to clear up!
I have booked him an appointment at the doctors next week, but I wondered if any Mumsnetters had any advice?
