Biologically speaking, the late teens or early 20s are the best ages to have a baby, according to Psychology Today. During this time, the reproductive system is at its peak and women have the lowest risk for miscarriages, stillbirth and other pregnancy complications.
Conceiving in the late teens and early 20s, while biologically ideal, may present many social challenges, notes Psychology Today. As of 2015, American society is constructed around smaller families with more women working full-time. Younger women are more likely to be unmarried with limited education; adding pregnancy to an already disadvantaged situation can be detrimental to progression.
