This is our new solution to keeping Judith out of the kitchen. She knows how to open the baby gate, and we just don't want her in there all the time (or in the furnace room which is accessed through the kitchen).
It's a dog leash, carrabeaner and eye screw. I told Dave it looks ghetto (especially with our messy pantry shelf in the background!). He thinks it's just resourceful. But hey, it works!
