What are the best wipes you've used when your baby has had nappy rash.

DD is teething, and we have here the first bout of real, honest-to-goodness nappy rash that we've seen. Not a bit red in the creases, which we've seen often enough, but red all over, everywhere that the nappy touches her skin. I assume it's because of the teething. Certainly the teething is a new thing.

She's doing a zillion little runny poos too. Which is part of the problem.

She's now so sore (poor darling!) that she cries when I wipe her bottom. I've tried the cotton and bamboo cloth wipes we normally use (too rough), and the disposable wipes we use occasionally (softer, but they have more chemicals and I doubt that's good). Everything hurts her.

What is the best way you've found of cleaning a rashy bum without hurting it more?
