I agree...pull ups don't work! We started potty training our daughter just after her first birthday. I bought her a potty and put it in the living room. I just encouraged her to sit on it then. When she made her "poop face," I'd rip off her diaper and put her on the potty. Then, we moved to just being naked. She only had a few accidents, but most of the time, she'd go in the potty. We left it in the living room for a while...and then when she was comfortable, we moved it into the bathroom.
She only wore diapers when we went out. I just wasn't brave enough in the beginning. She ALWAYS went pee pee in them. She was completely accident free in the house. She would even get out of the pool to go to the potty. But as soon as I put a diaper or pull up on her...it was like I was giving her permission.
So, I eventually just braved it. And, for the most part, she was fine. Like I said, I just let her run around naked. I'm not so sure that that was the best thing, however, but becasue for a while when I put clothes on her, she would pee in them. She didn't seem to distinguish between the diapers and the clothes. I did a lot of laundry!!! But, I think it was worth it! And cheaper than pull ups or diapers.
She's been potty trained (with clothes lol) for about 6 months now. But, she still has accidents at night. I do not have the energy to wash sheets everyday, so I put a diaper on her at night. Just last night, she got up and came downstairs after bedtime. She said, "I have to go pee pee" and went running to the bathroom...And then she stopped and said, "Oh, I have a diaper on. I'll just pee in it." I think she was wearing one of those Huggies Pull Up things with Princesses on it.
Another piece of advice that I got was to keep a potty in the car. This has come in VERY handy. She's used it on the side of the road and in parking lots. And...at least I know it's clean! Good luck! Traci
