Okay, so -- we've just finished dinner. Firstborn has retreated to the living room to continue his epic quest to restore the Core of Light to the Skylands, and taken his mother with him. I'm cleaning up.
Secondborn -- who just turned two back in the middle of April -- has been puttering around the kitchen with me. Now, as I watch, he reaches over and rips the child-protective cover out of the electrical socket on the wall. Still holding the protective cover contemptuously in one hand, he reaches down and picks up the cord for the air filter. This, he promptly jams into the wall socket... seating it correctly on the first try, I might add.
Then he casually drops the protector on the floor, reaches over, and turns on the air filter.
Explain to me again how this "baby proofing" stuff is supposed to work?
