After since my son was born in May, I’d been a bit obsessed with “new baby smell.” Where did it come from? And why did it disappear so quickly? Initial research was disappointing–mostly a lot of crackpot theories and denials that the smell even exists (blasphemy!)–so I decided to dig deeper, and wound up getting an article out of it. It didn’t hurt that the first significant study on the topic in ages was just about to be published.
