H.B.
I am sure you will get plenty of differing responses but here is what I did. I never did the pull-ups with my son. I just had several changes of clothing and washed a lot of clothes. My son took nearly 3 months to get the night time bathroom thing down. He is now dry full time. He is turning 3 next month. We had him put thick cloth training pants on but wouldn't use the plastic over for 2 reasons: 1. he thought it was like a diaper adn that didn't help, 2. he knew when he was wet.
With my daughter she was on pull-ups (this would be the reason we didn't use it with my son) and didn't train until she was nearly 4. So she didn't have any accidents at all once she was finally given the ultimatum. Act like a big girl (trust me, I knew my daughter and she was able to control it, it was a power struggle) or lose all benefits of being a big kid.
