Getting Ready for a Big Boy Bed

Last Monday John converted Jax's crib to a daybed.  We are getting him ready for his "big boy" bed.  It has been a rather easy transition.  The first day he slept in the floor during nap time but he slept in his bed during the night.  He still calls out for me when he wakes up in the morning.   We have been playing up the "big boy" bed for a few weeks now.  He's excited about getting his "real" bed for his birthday.  The plan is to have his new room ready for him to sleep in on his birthday.  It's exciting buying new things but a little sad to think how fast the past three years have gone by.
