Lights on, Lights off

A new trick for William... turning the light switch on and off. I went up to his room the other day to get him after he took his pm nap. I heard a clicking noise on and off, on and off, and saw the light flickering around the door.

This morning I went upstairs to get him and he had already turned the light on in his room for the day! He was playing in his crib with the lights on. So funny...
