I rarely have to use diaper cream.. but when I do I love CJ's BUTTer. I was using the unscented, but I just order the sampler that has like 8 different scents in it. Yum!! They all smell soooo good. And they're safe to use on cloth diapers without a liner. Oh, and it works awesome too. At the first sight of redness, I put some on and he's not red anymore within hours of applying it.
I also use California baby cream when I run out of BUTTer.
Here is a link that shows which creams are cloth diaper safe.http://www.pinstripesandpolkadots.com/diaperrashcreams.htm
What type do you use?
