...to the toddler bed this past weekend. I was having a harder time hoisting his *I'm guessing* 32 lb body over the crib rail. I was worried at first because there is no guard rail on the converted bed (it is an ikea crib), you just take the one side crib rail off and a small board is installed along the botton to keep the mattress from coming out. We placed pillows along the side so if he did roll out he would have something softer to land on other than carpet. The mattress is pretty low anyway, probably not even higher than if we had put a twin mattress directly on the floor. The first night, he did end up outside the bed (not sure if he rolled or crawled out) and was crying, but he hasn't fallen out since. The funny thing is that he doesn't seem to realize he can leave his bed freely when we are not in the room and waits until we come into his room after naps or in the morning before he pops out. I always think he is going to get up, turn on light, wander and play around his room because he is such a free spirit, but so far he has stayed put. If he continues to do well we plan to keep him in this bed for couple months after baby is born (baby can sleep in pack n play bassinet) and then possibly get a twin bunk bed set that can be used as separate beds initially. I would definitely consider a guard rail with the twin bed though. Just yesterday DS did a header over the side of the couch and scraped the side of his forehead...yikes!
