I read somewhere that it's a good idea to keep the crib handy when going to a toddler bed just in case the child doesn't take to it well right away. It wasn't really an option for us, but it worked out just fine anyway. Elijah LOVES his new bed. When Ryan showed it to him for the first time, he immediately knew what it was, and wanted to play "going to sleep" for a while. He'd climb onto it, lie down, then get off. We were concerned that since he could now get up himself he wouldn't stay in bed when we put him down for the night or just his nap, but he hadn't gotten up once in the few days that we've had this new sleeping arrangement. Although we can no longer prolong our mornings in bed. As soon as Elijah is awake, he gets out of bed and turns on the lights.
Funny enough, finding a top sheet to fit this toddler bed turned out to be quite a chore. I finally found one at Amazon, but I feel like they are overcharging, so we are using a twin-sized pink-striped one for now. :) As for a pillow, Elijah seems to be plenty comfortable without one, so we figured no need to worry about that one quite yet.
