DD was a bit of a nightmare for a while.
In disposables we found that smothering her bum in drapolene seemed to help lots.
In cloth, soaking silk liners in camomile tea and honey, and then putting them in damp (squeeze it out and put it in) helped soo much. The nappy lady sells silk liners... they are pricey, but I bought 4 and have never needed any more as it always heals by the time I get to using the 4th one.
Wiping with camomile, honey and baby oil worked well too, rather than babywipes or just water.
Goodl uck
