Congrats to you and yours! As a parent of teenagers (teaching your children to drive is a whole other level of terror), I'd have to say, it only gets better. Participating in the process of evolving your children into people is an amazing experience. And I have for years pointed at grey hairs on my head and associated them with certain events involving my children: "This patch is when you learned to ride a bike, and these over here is you lost in a mall, and this up here is two weeks of chicken pox..." Now that mine are all but grown, I have moments where I think "Dang it, I should have made more. These things are COOL." Plus, smart people need to have more babies. Good on you for getting on that and making some twins! R.
