You know when you hear a mom say "I just want to eat you up"? Well, she actually means it...kind of.

So, we've all been there when someone says "i just want to gobble you" to a baby. Well for women this is actually pretty much true. Not that any women are ACTUALLY going to eat a baby for real. However, the smell of a newborn baby is enough to trigger this huge surge of dopamine in the brain. This causes a women to think of think of the baby as a reward as it triggers what's call the 'reward circuit' in a woman's brain.

Researchers were unsure, however, if mom's hormone balances are altered when they give birth to trigger this thought by any baby. Or, if they only wanted to eat their babies in general.
