hi girls

can i just ask, what does fungal nappy rash look like? and what do you do to treat it? L has these weird sort of blistery pimply looking things- they don't seem to bother him or seem sore at all...hmmm not sure what they are, can anyone help?? otherwise i'll take him to dr on monday...
also, what's the best thing to use on excema? he has a bit on the back of his neck that he keeps itching
