Ryan Bounces in His Exersaucer on His Tippy Toes

Ryan loves his exersaucer/activity center. He can keep himself amused there for over a half hour at a time and enjoys the fact that he can bounce and explore the toys all around him at the same time. A funny observation that Dan and I have made is that Ryan always bounces on his toes (think en-pointe like ballet). Looks like it would hurt to me, but he bounces with his feet pointed and toes curled in. I tried to capture his bouncing method on this video, but it doesn't really show very well since you can't see his feet through the sleeper!
