Hey Heaven. I second the frequent changing advice. MCN can't go as long as sposies. Also, try to give her some nappy free time each day for a while - it might help to dry out her skin naturally.

I think some kids are just more prone to nappy rash tbh. If it makes you feel any better, DS gets a mild rash quite frequently in the folds at the top of his thighs and I've noticed it occurs when he's been in a nappy longer than about 2 hours.
