I've been using prefolds and bsww for about 6 months or so and my bigest problem is when the snappied diaper is not tight around his legs and so when he pees, it goes straight onto the cover. the cover cant stand that much mosture and now everything is wet. Ive tried diferent folds and tighter snappi-ing but it still happens. Not every time, but always at a most inopertune time, like when there is not another clean and dry cover. so, anyone find a way around this? Am I doing something wrong? They are simple and cheep, but sometimes I want do ditch the whole system.
