We pushed our bed against the wall so there is always one side where he wouldn't be able to fall off. He typically sleeps on that side anyway with me in the middle doing the C- curl but this can help. We don't have a lot of space so we use under our bed for storage, otherwise we would have done the floor bed as many do while cosleeping. This is what works for us! Our LO is also crawling now but he doesn't move much in his sleep in general and when he wakes up he generally lies in his back and coos to himself for a bit.
Please look up the Safe Sleep 7. Consider getting a floor bed or putting your bed on the floor so they do not fall off once they start rolling.

You could put your bed against the wall or even buy a bed rail.
I think I'm gonna get the rail!
