This makes me muse further: what if indeed all these babies would be nursed by
other wonen (which indeed will probably be the case), then the birth-mother
would become pregnant sooner, have more babies alltogether, more babies alive
(?), so *more* chances of passing on the genes that count for lactation
insufficiency on to their offspring? Or do I miss something? Or is primairy
lactation insufficiency not inherited but merely a bad-luck variation? Just
wondering.
