Congrats Jeff. My wife and I are doing the same thing but in reverse order. We have two beautiful identical twin girls, 2 years old. My wife is now pregnant with a third, who happens to be a boy. As far as raising twins, your highs and lows get amplified even further (if you can believe it). Its unquestionably more than twice the work and difficulty. But much as you cannot explain the pleasure of children to people without them, you cannot explain the pleasure of twins to parents of singletons. Seeing them grow up together to become best friends, constantly looking for each other and playing together. Its truly magical. Feel free to ping me if you want to chat with someone whose gone through it and survived.
