Advice to Amy
After reading this horrible article in yesterday's NYTimes Magazine When One Is Enough, and its ending sentence,

I had a boy, and everything is fine. But thinking about becoming pregnant again is terrifying. Am I going to have quintuplets? I would do the same thing if I had triplets again, but if I had twins, I would probably have twins. Then again, I don't know.

my advice is, simply don't get pregnant again. Ever.
