I have seen great reviews on FuzziBunz but we have one, and I hate it - it ALWAYS leaks, even after I "stripped" it - but maybe we just got a lemon. My friend uses BumGenius - but she purchesed the stuffing with them, so I don't know how bulky they get when used with a prefold. An additional benefit of the BumGenius is that you can get the one size fits all, so you can use all the diapers on either of your kids. I use prefolds and with my son I used prowraps and LOVED them - super economical and NO leaks. Every once in a while there would be a red mark from the velcro on his leg, but that was because I didn't secure it well or it was time to move up a size. I use bummis super whisper wraps with my daughter, and love them too - I know these two brands don't have the fleece, but they work great for us. I don't have any ideas for you for night time, we just use diposables at night because of the leaking - sorry I'm no help there. Check out craigslist and buy different brands used, then if you love one kind you can get more!
