girl just wanted to say i'm there. actual conversation between my son and me this weekend, as he's fussing and fighting and whining and wiggling around in his high chair:
son: me stuck!
me: are you done eating? want to get down?
son: NO!
(since he hasn't touched his food for several minutes and is about to go into all-out fit mode, i put him down from his chair. he promptly climbs back into it.)
son: mommy me stuuuuck!
me: son, do you need help getting down? are you finished eating?
son: NO!
my point- i know the two's. i feel for you! as far as getting out of bed, if you close the door on her (making sure her bedroom is safe for her to hang out in alone) would she eventually get back in bed? maybe she's just not ready. our basic rule is, once in bed, in bed. he may get up and wander (especially if he's not wound down and/or is mad about me putting him down) but after a few minutes of rebellion usually gets right back into his bed and goes to sleep. you've probably already tried that, sorry. i know, she's two! sorry i don't have any better advice, but good luck...
