Watching over lil' sis

Yo gets all happy and excited when he sees his sister, and he's showered her with lots of kisses.  I've certainly been surprised at how much love he shows Mika.  The boy still needs to fully comprehend the concept of 'being gentle' with his baby sister, though; his gentle patting sometimes transitions into an inquisitive poke, pinch, or even solid thwack before we can react.
