Right before Dylan turned 3, we made the switch to a big boy bed. For no other reason that well, I wanted too. He never tried to climb out of his crib, and he really loved it. But I was ready for him to try to be in a big boy bed. We took the front off his crib, and he loved it. He stayed in there, for the most part. He would get out to play in his room, but didn't destroy things and was super quiet, so it didn't really bother me.
He was so excited to go pick out a new bed. Sadly, we had to order the one we wanted, and he had to wait a few days. In the meantime, we picked out a new full sized bed set, and got it all ready to go. Fire man was the theme.
The day it arrived he was like a kid in a candy store. So giddy. He has been great with it. Never fallen out and doesn't jump on it. He looks very little on it on the monitor though!:) I love his big bed because we can get in there with him to read books and tells stories when he goes to sleep. Just another sign, my baby is getting to be such a big boy. *tear*
