The definition of flexibility (adj) is 1. capable of being bent or flexed 2. capable of being bent repeatedly without injury or damage. The second definition is my favorite. I never thought Jake was going to be able to put his big toe in his mouth. I just didn't see it happening. Not only did I think he was going to be too big or long, BUT mainly because Chris and I can't even TOUCH our toes standing up (yes, that is true). We would be the opposite definition of flexible. So, as I watch Jake continually put his toes in his mouth...and do it without injury or damage...it amazes me! I keep telling him that he better enjoy it while he can, because he doesn't have flexibility in his genes.
