This one is gold, people, GOLD!
Really, I was just *done* with that stupid little Elmo potty seat (don't even get me started on the little potty that you have to empty the pee and poop from). It's so gross to touch, and I didn't want to deal with it because they'd never get their little penis's to point below that so-called guard, and there'd inevitably be pee everywhere, well, at least all over the top of the seat.
But when he just sits backwards, he doesn't fall in, and he kind of holds himself up, too (what, we're washing our hands after anyway).
So when we started potty training him, he wanted to sit backward and I let him. Now, wherever we go, we don't have to bring that ridiculous pee ring (like I did as a noob mom with the first two). He can go potty and not be afraid of falling in.
Boom! Third time's the charm.
And of course, the NUMBER 1 TIP OF POTTY TRAINING is to put them in underwear and don't turn back. No Pull-ups, no diapers. Just do it. ;)
ETA: I don't have any experience potty training girls, but I don't see why this wouldn't work with them, too. Anyone done it?
