My husband and I also have two sets of twins. We had boy/girl first and then two boys. I too cried at the news, it is a little overwhelming. When we had the first set my husband jokingly told the nurses, "we'll be back in two years for the boys". It was actually 27 months when we were back with fraternal boys. Then he joked "we'll be back in two years for the girls" Twenty two months later we had a girl (but just one this time). We had 5 in 4 years. I am the youngest of nine so I was use to a crazy household. Now they are all grown with families of their own. It was worth every minute as crazy as it was back then.
