I think we've decided that option #4 (enjoy our one son and get on with our lives) is probably the right one for us right now. We're not even going to bother with the testing. In 6 months or a year, if we want, maybe we'll reevaluate and if we feel like we're missing something, there's nothing stopping us from trying some more.
I'm really happy with the thought of our family the way it is. Sure, it would be nice maybe to have a girl, but girls are problems. They can get pregnant! ;) And I don't really feel this burning need for another child. It would be nice, sure, and certainly it's something we wanted because we tried but I'm feeling perfectly satisfied with the one.
I think the only thing bumming me out a little is not getting to be pregnant again. I really liked being pregnant! :) Even gaining 55 pounds and morning sickness and being swollen and getting kicked in the ribs. It was so much fun!
Jen wasn't feeling well today (a virus of some sort with chills, fever, aches, etc) and Nate was so sweet. At one point we called him doctor Nate and then he said he wanted to be a doctor. What a sweet child we have. If he sucked, we'd definitely have another, but I think we'll keep him. :D
