His ability to play hockey games on the PS3.
He LOVES this recent skill and would play it all day if we let him. The scary part is how good he is at it. John has to set up the games for him but then he does pretty well against the computer for a three and a half year old!
I feel like he's way too young to be playing video games. I wanted to delay it as long as possible because I knew it was a matter of time and I hate how kids get addicted to them.
But sometimes its just really nice to have him sit quietly on the couch instead of running around bouncing off the walls!!
