My kids were like that at that age. The crib was no longer an option. We put them in toddler beds.. even worse, b/c they could push the bed all over the room, one morning I came in and the bedframe is standing up straight against the wall! But then again, it was just a cheap bedframe. So, I ended up putting the mattress right on the floor. It worked for us! Try that and see what happens :)
