Superhero Wrestle Mania

I don't know who gets more excited about superheroes now, Harrison or Brooks. But both seem to squeal with delight whenever Daddy decides to put on his Batman costume to chase them around the house. I'm pretty sure Brooks just likes the interaction but she keeps up like a champ while Harrison and Robert go back and forth in pursuit of a villain. Of course, this hot pursuit is always right around bedtime making it really easy to transition into lights out. Why do I wonder why it so hard to get Harrison to sleep???
