Skybie (hello hon, long time no see ) I'm guessing fc is fabric softner, Loula correct me if I'm presuming wrong? If you did mean fabric softner than nappies can't be washed with it from my understanding. I'm glad this thread is helping someone else too cause when I posted it I thought surely this info is on BB already I manily wanted to know about the amount of washes for absorbency, I didn't want to go putting the prefolds etc onto bubs butt and find they leaked or didn't absorb
