My 17 month old is getting incredibly close to being able to escape his crib. I'm starting to get nervous, so I've been thinking of our next step before it pops up on us and the situation gets dangerous.

My son is an intensely active/restless sleeper, so I'm also nervous about him sleeping in anything that doesn't have bars all the way around. He literally rolls from one end of his crib to the other about every 10 minutes during the night.

The safest option in my mind, is to purchase the crib conversion kit for our crib. It has a large gap, but it's relatively closed in. The main drawback is that it's $200 for the kit. For that kind of money, unless someone can tell me that their toddler lasted a good year plus with the kit, I can't justify spending it.

The other option is to buy him a twin mattress and either put it on the ground,, or get a bed frame with rails. I'm just totally convinced that he's going to be rolling off all night long, either way.

Does anyone else have a restless sleeper on their hands, and how did you handle the transition to a big kid bed?
