Kyle is at the stage where he's getting into everything, trying to figure out how it works. We've got a deconstructionist on our hands. When we tell him No, he does it again more emphatically and then stops on the second No. Timeouts still work, though he needs closer to 3 minutes and needs his light dimmed in his room, otherwise it's play time. We can't give timeouts for everything (or they'll lose their effectiveness) so he gets them for playing with our computers, playing in the trash, and causing injury like pulling Eric's hair.
