Girls are always talking about some newborn baby smell. What is that smell, anyway? What kind of smell is it that a newborn baby has (even after being cleaned, bathed, and dried)? And why??

One person described it to me as something like hot buns (no pun intended) fresh out of an oven. Fantastic, I mean, who doesn't like the smell of fresh baked bread, right? And then you start to think about what might cause that smell ... and you realize ... yeast. Yuck. Nasty.

So what is that smell again? And why do girls seem to enjoy it so much? And is there some commercial opportunity here, or can I just bottle it myself to attract girls?
