Lily has gotten really bad nappy rash. Probably due to the bad heat and humidity here. It doesn't seem to hurt or bother her at all but it looks really terrible. Mostly on her 'girly' bits. I've used Bepanthen, Curash nappy rash cream and the anti-nappy rash baby powder and none of them have made a difference at all. Is there anything that would work really well? And what can I do to stop it from returning? She's never had it this bad before and Bepanthen had always cleared it up within 24hrs. I always the anti-nappy rash powder and a bit of cream after nappy changes, but this time it hasn't stop it for some reason...
