Is there a biological explanation behind sudden-onset baby lust? How do we know when it’s time to get pregnant? We’ve heard so much about the biological clock, but not much about the alarm mechanism that’s supposed to let us know this thing is working. Concerned about my ambivalent feelings about babies and motherhood, I decided to further explore baby lust. I wrote about my findings in an article for ELLE called “Clock Watcher” (February 2011).
