We baby-sat my friend, Megs', kids once a week for several weeks last fall while she had a standing appointment to go to. My kids adore her kids so much and they play really well together. Sadie and Brynnan usually spent the time running around and screaming, Jonas and Dylan spent the time playing video games together, and Tinian spent the time nestled in my lap, where it was safe. Every now and then he would get brave and wander around.
One night, Dyl and Jonas were playing Super Mario Bros., and there was an unused third player Wii remote left on the ground, with a steering wheel still attached (for use when you play Mario Kart). Tinian picked it up and started shaking it, staring intently at the screen:
It made me laugh so hard that Tinian had picked up on this. You can tell he comes from a family of gamers. :)
