I tend to use a disposable liner on top of a fleece liner. In the past if the rash has been bad I've soaked the disposable liner in camomile tea and laid it (still damp) in the nappy. It does help, to a point, though I sometimes just have to bite the bullet and give her a day in disposables to get a rash cleared up. In terms of cream, I swear by CJ's BUTTer. It's save to use with cloth nappies, and is absolutely fantastic. I actually used it on my face today - I've taken some kind of mad allergic reaction to my normal skincare routine (it happened in my last pregnancy too) and the BUTTer stopped the itch and stopped my skin feeling so tight. I'll probably reapply it before bed as I can feel the tingle starting again, but that has lasted all day.
