When I was a teenager, our house had a door like that. It was called the-sleepwalker-waker-upper door.
That sure would do the trick!
I feel like that's a challenge waiting for Aubrey to conquer. How to climb up and get yourself in the door.
We should get a bouncy-castle-type pad under there or a trampoline.
We should have kept our old mattress and installed some rock climbing holds. It would be cheaper than the balcony and a lot more fun.
