Why Do Babies Smell So Good?

The video explores the phenomenon of 'new baby smell,' a real scent that is often compared to new car or house smells. It discusses potential causes, such as amniotic fluid and Vernix caseosa, and highlights the challenges in studying this scent, which fades after six weeks. A 2013 study found that baby smell activates reward-related brain areas in women, especially new mothers, suggesting an evolutionary benefit to encourage maternal care. The video also notes the lack of research on how this scent affects fathers.
