We all know that a parent's love is unconditional, but that's doesn't mean they want their kid to come out looking that baby from Benjamin Button. So if you're tying to figure out how cute your baby is, just ask a premenopausal woman because they're scientifically proven to have the highest cuteness sensitivity.

Back in 2009, researchers at the University of St. Andrews in Scotland decided to test how good different groups were at determine baby cuteness. They found that women aged 19-26 and 45-51 were more sensitive to cuteness than any male age group. Premenopausal women and women taking oral contraceptives which boost the levels of reproductive hormones also did better than those who weren't taking them. The theory here is that the more estrogen and progesterone a woman had, the better she was at detecting baby cuteness.
