How come everyone I know is about to have a baby? Or is that "everyone I know is about to have babies"?

Am I the only one who has read this important baby literature?

In 1980 as well as 2000, childless couples were generally happier than those with children. The study didn't explore how children or the absence of them may contribute to the stability of marriages.

Update: After typing this, I headed over to thingnamer.com, only to discover that Tate and Sarah have moved out of the "about to have a baby" category, and into the "just had a baby category". I am too lazy to retitle this post: "How come everybody I know has just had a baby, or is about to have a baby?"

Congratulations to the new parents. Give us a few days notice before you open anything good...
