I just found out a great new product called the "potty hammock." It's perfect for when you're little one says "I have to go potty!" at the supermarket. No more holding him/her over the bowl or awkward, hard plastic covers (I always hated them!) Made out of parachute material (so you can easily rinse it off) you just slip it over the toilet and there is a perfect size hole for a little tushy to fit comfortably.  (It also makes those public toilets sanitary by covering it up)  Then just rinse off -- it dries instantly, put it back in the little pouch (also of parachute material) and stick the pouch in your purse. It's small and lightweight. A GREAT solution! You can see it here at http://www.pottyhammock.com/
