she'd think that because she was wearing pullups, she'd be allowed to pee her pants and not even TRY to make it to the bathroom

Not necessarily, but if it got to be a daily occorance I wouldn't care anyway. At least its an easier cleanup & no embarrasment if it happens at school..

I know for sure she would. She already thinks its okay to just pee in her pullup while in bed rather than get up and go to the bathroom at night (before she's fallen asleep).
I've gone in there and told her to stop screwing around an hour after she's gone to bed and checked and her pullup is all wet and I've gotten angry at her so many times and told her 10 ways until sunday that she has to GET UP and GO to the bathroom if she needs to go pee, she can't just use a pullup. (sometimes, she was geting up to change into a new pullup in the middle of the night because she would pee in it and then not want to lay in it wet. but she hasn't done that in a while since I spanked her pretty good for doing that).

Hope the week flies by!
