When I was 3-4 yo I rolled out of my twin bed onto the floor. I then rolled under the bed later on that night. In the AM my parents saw the empty bed and thought I was kidnapped. I think I also opened the window through the course of the night or something which freaked them out further. I think I woke up an hour later and was like WTF haha
Afterwards my father bought hospital bed rails and screwed them to the frame.
