Hi Sherry,
This may sound cruel - it did to me the first time I heard it - but lock her in her room.
Both of our boys (3 years apart) were around 1 1/2 when they started climbing out of their cribs, and we had to move them into a bed. Friends of ours (who had gone through the same thing) suggested locking the door.
We tried it and it worked. We actually switched the lock on the door to lock from the outside.
First, we all but emptied the rooms - no sharp corners, no lamps, no breakable items in reach, nothing to climb on - nothing but a bed within the baby's reach and a monitor listening to/watching him. Just a nice safe room - kind of like a really big crib.
They both cried and threw fits the first few times they were put to bed and figured out they couldn't just follow us out the door, but within a few weeks, they got the concept - and we rarely had to lock the door after that.
Our youngest is 2 and can be quite mischevious, so when we he argues about going to bed, and at nap time we lock his door, knowing that he'll try to sneak out.
My biggest fear in doing this was that they would need to get out of the room in some sort of an emergency situation - like a fire (as random is that is) or a dangerous storm - and couldn't. So, even though my husband reminded me that they were in that same "trapped" situation being in their cribs, I always locked the door and busied myself folding laundry or cleaning in a nearby room, and when they fell asleep (usually within minutes) I'd unlock the door and leave it open a crack.
It helped them to understand bedtime, keep them safe and keep us sane instead of going mad trying to reason with them to stay in bed and chasing them back into their rooms and into their beds every night.
Good luck!
