Another study I'm glad I wasn't a part of

Moms Prefer Smell of Their Own Baby's Poop

What kind of sick mind decided to study this one?

"In a new study, 13 mothers were asked to sniff soiled diapers belonging to both their own child and others from an unrelated baby. The women consistently ranked the smell of their own child's feces as less revolting than that of other babies.

This effect persisted even when the diapers were purposely mislabeled."

Apparently there are plenty of these studies going around:

"The finding is among the latest in a series of studies suggesting that humans can determine biological relatedness through body odor. Another recent study found that mothers more accurately identify and prefer the smell of their biological children over that of stepchildren."

That could explain the whole Cinderella thing, I suppose...
