Oh God....I know how you feel! Archie did that one time and did the exact motion you're talking about, but he turned out to be fine later.
My aunt has a MONSTER two-year-old son. She's always telling me to bring Otis over to play, but I don't trust her son one bit. He's into hitting, jumping, throwing, choking, kicking, and when we go there, I'm always on the edge, and I hold Otis about 90 percent of the time, or Otis will hide.
