|We did this when our XS sandy's were used up, and it worked great. We had a 5 or 6x per day ebf crazy pooper, so my only suggestion would be to have 6 covers like we did, since often the poo leaked out onto the cover (but never past it!!) It's very easy just to rinse of the cover at the sink and hang dry in the bathroom, and it's dry in 10 or 15 minutes. Cheap and easy - we just folded the prefolds into 3 and laid them into the diaper. Very quick. Once she got a little bigger, they leaked more, but we should have moved up to the full sized prefold at that point. Instead, we went to MEOS and have used them ever since.
