I used Gerber training pants. They are cloth with a thick middle to allow them to get the feeling of being wet but absorb as much as possible, sometimes it would go down the leg and get the floor wet. I found them at Wal-mart and Target in the sections of Gerber clothing. I think they came in a pack of 2 or 3 for about $8-9. Hope that helps. Good Luck.
