The how to's of the Chinese potty with a 2 year old

I am still working on perfecting the "potty technique" with a 2 year old. I was quite excited to discover Maggie was potty trained and we wouldn't have to mess with diapers. What I didn't think about is what using a public toilet in China with a child would mean. If you have been to China you know that the potty is a hole in the middle of a stall minus the toilet paper. When you take a child to the potty you have to hold them over The Hole. My first attempt at this Maggie peed all over my shoes - thank goodness they were waterproof. After that episode I realized I didn't have her legs positioned quite right. On our second attempt I knew I should pull her legs way back and up - think lady birthing a baby. This time around her pee shot up and soaked the backside of her pants that hung around her ankles. In all of this you have to fumble around for the toilet paper in your pocket and make a dash to wipe pre-dribble. I thought I would be much smarter to have the roll already ready in my hand, but in maneuvering and holding 28 pounds the roll dropped and rolled out the stall (TP is a hot commodity so I was so disappointed). I've got about 8 more days to many to work on this. Would love any tips
