Dive right in!
The boys (all three of them) discovered a shared love of the diving board this summer. This video doesn't quite do them justice, but it is fun! I am so thankful for the swimming lessons that Jake and Josh have been taking. Not long ago the thought of jumping off of a board into 10 ft of water would have struck terror into the heart of at least one of these gentlemen. What a difference! They have such confidence and joy in the water now. Different boys, different styles; and it turns out that daddy is an awesome diver! He must have been incredible as a teenager, back when he was life-guarding. So many facets to him; after thirteen years of marriage, I'm still learning about who he is. And each new piece makes the puzzle even more interesting and exciting!

New blog
I find myself with a desire to publish my boys' writing, and perhaps some of my own, in a single spot. Therefore, I have created yet another blog for this sole purpose. You will find it at www.OurIEW.blogspot.com .
