I thought I was allergic to wool too....and I am, sort of. It turns out I'm just allergic to the processing chemicals used for mass produced wool. I was told this is the case for most people and to try out natural wool. I did and haven't had any problems. The wool used to make diaper covers/longies/skirties/etc is natural wool without that processing.
I have never found the love for wool, though I do like the wool skirts I have seen for baby girls. I think its because I am allergic to wool I guess
most favorite is a fancy cloth diaper
Cloth diapers are one of my fav too but I really like the plain ones on newborns although I was guilty of fancy from time to time. Wool wins me over every time though!
