Where does a two year old get it? Boy if I could bottle that energy and market it, without the dangers of over indulging in a caffeine like substance, I would be rich. I watch my son, who will be two on May 2nd, and he just bounces and runs and climbs. One of the funniest things he does is what I call the "butt bounce". He will sit on the floor practically in crossed legged position and proceed to bounce on his butt in a circle. Everyone who has seen this phenomenon is very impressed and wonders how he does it. The boy gets serious air under that bottom. He use to bounce in his exersaucer that way also, he would bounce without his feet touching bottom. Any ideas on how to market this wonder drug called a two year old, let me know.
