Miles isn't great at video games yet, but he has discovered that there are certain areas on Super Mario Bros. 2 where he can "split the character" between both ends of the screen, a detail he found endlessly amusing. A reminder that success in video games is, at times, subjective.
An upside to Miles's teething -- I've finally been able to introduce him to The Legend of Zelda. In teething toy form. I think he was most fascinated by the difference in appearance between the two sides.
