J.S.
You've got lots of good advice so I will second what some of the posts said - even unscented wipes are not recommended for sensitive skin. SInce my little one had her first diaper rash at 2 weeks old the pediatrician said to skip the wipes - use a wet washcloth instead and it will not irritate her as much. What we did was take the Gerber cloth diapers and cut each one into 4 squares - these became out diaper "rags", distinguishable from her washcloths just because I didn't want to use the same cloths on her bum and her face everyday.
Also, once a rash blossoms you might try letting her bum air out - wear a dress and no dipe at all on her. Or put a pair of training pants on her - no creams - just let her air out for an hr or so after changing her. We use Balmex on the rash and A & D ointment prophylactically at all times to prevent rash.
Best of luck,
J.
