ELI5: Why are children more likely to fall off the bed while in deep sleep than adults?

I'm in my 30s and the last time I fell off the bed was when I was 7.  What makes kids fall off bed and what prevents adults from falling off?

When you sleep your brain turns off your motor-cortex (the thing that controls your limbs) so that you are basically paralyzed. This is also the reason you sometimes feel like you are falling when you are about to fall asleep and suddenly jolt yourself awake.

In children this function is still developing and sometimes it doesn't turn off all the way or at all. Thats why kids also sleepwalk much more often than adults.
