Woke to productivity!

I woke this morning at 2am and worked for an hour and a half before making the dreaded mistake of allowing myself a "power nap" from which I rose at 5am. I found Amy half asleep on the hallway floor at the top of the stairs at 2am. She's learned to climb over the gates so I anticipate a fall down the stairs soon. I wonder if it would simply be safer to leave the gate open.
