Calmoseptine (can get at wal mart, not cloth safe)
Lansinoh ( I've used with cloth diapers and it's never affected them)
Triderma from toys r us (I've read it's safe for cloth. Its never affected
One main thing that has helped my son before is a hair drier on cool setting at diaper changes. The air is good for the skin and it feels good to his bottom.
