DS is teething and his poo's are really bad and giving him the worst nappy rash ever.

I was using a paw paw salve that i got from a cloth nappy site which usualy does the trick for slight nappy rash but is doing nothing now as it is so bad.

I am using Bepanthen which is slowing working but i would so much rather use a natural cream.

Does any one know of a really good nappy rash cream that is natural?
