My wife, our son and #3 daughter went to St. Cloud this morning. The two kids are going to have their jaws broken - and put back together in a better configuration.
I think that, on the whole, it's a good idea. But they're not exactly looking forward to it. I'd be a little concerned if they were. What's going to be done isn't cosmetic, by the way: their jaws don't line up all that well, and the series of medical procedures is intended to make things more functional.
This afternoon, I got a call from my son-in-law. He's got a new tractor - and sent three photos of it, via email. Well, two of him and the tractor: another of my daughter and a trailer. Those two are definitely settling in.
