It must be genetic. I don't think there is a kid in our family that does not love the pool. At age 2 1/2 Noah loves to put his face in (by himself, after counting to three. And he completely submerges it, slowly with great intention), 'walk' on his hands in the baby pool while kicking, he can blow bubbles and when he accidentally goes under water he bounces right back up by himself, unscathed.
Yep, a late morning spent at the pool makes for one happy (and hungry!) little Noah.
(And let's be honest; I welcome any opportunity to feel momentarily weightless these days.)
