The TV stare

Henry is obsessed with a VHS video, "Elmo goes the the Fire House", that he got from his Grandma Garlits. He asks to watch it constantly (asking by pointing at the TV and saying, "Tssssss", since we still aren't saying any words). He usually gets to watch it once a day, we limit it otherwise he'd be glued to the TV all day. I wouldn't care as much if he interacted with me while we watched it, but he doesn't budge... he gets as close to the TV as he can and stares in a frozen stance.
