One night I was babe sitting and I was trying to put the girls to bed but Audrey (who is five) kept turning on the lights.Finally I got tired of it and thought of something.I got out some tape and went into the bedroom, I taped the light switch,tested it, and it worked! I couldn't turn on the light.So I closed the door and muted the TV so I could hear what Audrey would say when she couldn't turn on the light. I waited until I finally heard Audrey say "why can't I turn the light on?" I started laughing and didn't have any light problems for the rest of the night.
