Cloth diapers

G.
I just started on cloth diapers 2 days ago and noticed my 4-week-old has a rash. Any other cloth diaperers who noticed a rash with the cloth diapers? And what do you use to clear it up? I'm using cotton pre folds and fitteds with a PUL cover and changing every 2 hours at least  ( more frequently than the sposies).
