Puting a career ahead of having babies has far more negatives than postives. If a woman waits until 40 to have children, she will be in her early 60’s when the child graduates from college. That is sort of old for a college mom. But, she will be about 50 while her child is still in grade school. again, sort of old.
Motherhood is unique; assigned by God. As mothers defer to competing interests, the data should show, very clearly, that the children suffer! I think it possible for mothers with school-age children to still make a worthwhile contribution to society, in various fields. They have throughout history. The problems start when mothers place careers ahead of children.
