Hi J. - We made the move from crib to bed last weekend for my 2 year old son, birthday Dec. 2006. He was starting to climb out of his bed and it seemed like the time was now... The first night he was a little nervous, but our older son slept with him to make him more comfortable. The next night and during all of his naps he is just fine. I think it is funny how he waits in his bed for us to come into his room when he wakes up, rather than getting out of bed on his own.
We got him a twin size bed, because his is the smallest bedroom in our house. It is also a loft style, though not very high, giving him some play space underneath. I would never have purchased the loft style for my older son who is very clutzy. But, this son is very coordinated and like a cat, always lands on his feet - or well padded diapered bottom, LOL!
My older son, with the bigger room got a beautiful full sized antique four poster bed. I added the side rails to keep him from falling out. He usually sleeps on one side of the bed next to the rails. Also, he didn't move into the bigger bed from his crib until he was closer to 3.
All kids are different, what works for one, won't necessarily work for another.
I am sure that your daughter will be fine in the full size bed.
Good luck with your move when it happens!
W.
