We packed up and put away the crib. For a couple of months anyway.
I can't believe how easy this transition was for us. The best advice I got from other people was "do it early" so we did and it worked like a charm. For the past two nights she has slept in her new big girl bed with no problems. She waits for me to come in and get her in the morning and hasn't tried to climb out (yet)!
So my advice, if there is a reason you need your first out of the crib (assuming you don't want to have 2 cribs). Make the switch early!
Here is her bed. From Pottery Barn, but we got it off craigslist : )
