We went to ScottyPotty.com and purchased the thick underwear. He's totally comfy running around in them during the day so they can be multi-purpose if you want them to be. Then we got the waterproof plastic underwear to put over them at night. They work great although we do still have our nights where it leaks through to the sheets. But that's what the waterproof sheets on the mattress are for - lol! We cloth diapered as well and I am so glad to be out of diapers completely now! We never did he pull-up route as these fit the bill! Happy Potty Training!
