Hi L.,
You've already received a lot of good advice, I'll just tell you what worked for us. We have a variety of diapers: prefolds and fitteds (kissaluvs) with bummis and wool covers, fuzzi bunz pocket diapers, one size pocket diapers (bum genius and haute pockets), and all-in-ones (thirsties and bum genius). across the board, the bum genius one size diapers fit the best and leak the least. all of the diapers have leaked at some point, probably user error or just an extreme load. but the bum genius are the best for overnight and i think they're the best on the wallet in the long run because you just need the one size. good luck and feel free to contact me if you want more info
