T.S.
I have twin girls who are 6 now. They potty trained at 20 months. I put them in training pants with plastic pants over them. One of my girls potty trained in one week and the other took that week plus a week. I don't believe in pull-ups, it confuses them. I'll warn you the 1st 3 days we went through 32 pairs of panties a day (16 each). It was constant, but after day three one of my girls really got it and the other learned to hold it longer before she had her accidents and so we progressed. You will think you have bitten off more than you can chew when they pee constantly, but it is worth it to stick it out 1 week with constant accidents and constantly taking them potty. We also spent some time outside in the back yard where I just had them run around with a shirt and no panties and then when they peed it ran down their leg and they got to experience what they were doing. I put the potty chair out there and when they started to pee I rushed them to the potty chair. Then we could just spray down the patio.
When you are in the house, the plastic pants contain the pee. I could see it sloshing around between their legs so I would stand them in tub to take them off and wash them down. I did use very cool water to wash them down when they had an accident so they didn't think having an accident meant one on one time with mommy with a nice warm bath. It was chilly and uncomfortable and I would talk to them about using the potty and not peeing their panties. Good luck!
