On and Off

Lately Blake has had a fascination with turning the lights on and off.  When I pass by a light switch he grunts and points until I stand by the light switch so he can flip the switch.  Today I showed him how to put a little chair under the switch and he can get up and turn the lights on and off when he wants.  For the next 15 minutes all I heard was a little red chair being drug around to all the light switches, and then hearing and seeing the lights turning on and off.
