I think the problem is integrating family life with the rest of your life. Right now both concepts are completely orthogonal, so when you start a family suddenly you have a much bigger management problem.<p>(I Am Not An Anthropologist, but) My understanding of traditional hunter gatherer societies is that women would keep on working even with a small baby. The baby could be strapped to the womans back, or simply kept close by, so that the woman could keep working but still have quick access to the baby to nurse it when needed.<p>When the child got older, they would have the entire tribe looking out for them, so there wasn't a need for constant micromanagement. We have daycares, but that only lasts half the day. After work the parents are expected to dedicate the rest of their night to supervising. That's a big (and unnatural) time commitment, in my opinion.
