The researchers started by applying three different theoretical viewpoints about why baby fever might exist and where it came from:
- The sociocultural view: People want to have a baby because they are taught gender roles. Women think they should have children because society says that is what they are supposed to do.
- The byproduct view: Humans experience nurturance. When they see a cute baby they want to take care of it, and that makes them want to have a baby of their own. Baby fever is a by-product -- it is nurturance misplaced.
- The adaptationist view: Baby fever is an emotional signal -- like a suggestion sent from one part of the mind to the other parts -- that this this could be a good time to have a child.
