Yes, after driving Mommy and Daddy nuts ;-)
Maybe the solution would be for one parent to sleep in the room with them for awhile. If they’re able to understand ‘parental displeasure’ at that age, it might deter them from nightime antics long enough to get them out of the habit.
(I think I’d carpet the room in memory-foam, too - and keep good insurance. There are bikes and skateboards and all kinds of things in these daredevils’ futures ;-)
