A., my first son moved to a toddler bed at 17 months (his brother was on the way and we needed the crib!) We bought him a little toddler bed and put it in his room next to his crib. We had it in there about 2 months before the "big move." He got used to seeing it in there and he was able to play in it before he actually slept in it. On the day of the move, we went cold turkey on the crib...we took it apart and moved it out of his room, so there was no going back. It's a good thing we did that, because I think we would have folded if it was still in there. To be honest, the first night was a nightmare, he didn't have the "security" of his crib anymore and he wasn't too happy about that, so my husband and I took turns sitting on the floor next to his bed until he finally fell asleep. He slept pretty well, but if he woke up at all, we had to go back in there to comfort him (where usually he would fall back to sleep on his own in his crib). But after that, he got used to it. He's now in a full sized bed. My other son will be two in August and we're really not pushing to move him out of the crib (no siblings on the way this time!) He doesn't try to climb out yet and he loves the security of the crib, so we'll wait a little longer. PLUS, we have a big move coming up and don't want to make any major changes until after the move. Maybe we'll do it on his birthday??? Anyways, good luck with the switch! I like what someone else said, let HER pick out the bed or bedding set, maybe it'll make the tranisition easier if she's excited about it! Also, try reading her one of the books about moving to a big bed (we had the Elmo one, and he loved it!)
