Research shows that new babies give off an odor that appears to make women more aggressive -- and men less aggressive.
The other day I found some interesting food for thought about the relationship between newborn babies and their parents, mediated by stimuli related to the sense of smell.

The subject was further explained in Italian news outlet Focus in March 2022, and it is their description I have followed here.
