Hi! My baby girl out of nowhere developed a horrible nappy rash, so much she cries when we change her nappy, we've tried changing nappyies, wipes, just using cotton and water, giving her nappy free time, oat baths, aveeno, sudocream, Vaseline and her poor little bum is still so sore, even to a point I changed her a minute ago and it's all red and one sore spot was bleeding a little 🥺 I feel so horrible for her because this can't be nice, I change her as often as possible so she's not sat in it for ages, she has lots of nappy free time when we can but I don't know what else I can do to help her, has anyone got any advice? TIA x
