My 9wo has had some nasty nappy rash - really red all round the front of his nappy area. He was in cloth, so when it started getting bad, I switched him to sposies. We saw the doctor who prescribed Nystan, which didn't touch it. She then prescribed Canestan hydrocortisone, which cleared it really quickly. However, even in the sposies, it seems that if I leave him in a nappy for more than about 2 hours, he starts to get red again (we're still using the hydrocortisone - it's been about a week).
Could he be sensitive to his urine?
