Well, I think the geneticists are guessing. One day they may find this theory of parental conflict ridiculous. I don't know. But I do recall that when I carried both my children I had trouble with my teeth (cavities) and the dentist said this was common during pregnancy. So the fact that a child draws resources from the mother is actually quite feasible. How else does the fetus live, but from the mother's resources?
I love this comment:
(Young) children accept the differences between people without thinking, and envy can probably only develop if it is suggested to them
I think so. We are taught to notice minor differences (and it is minor). As for envying the womb--I agree both penis envy and womb envy seem like absurd propositions to me, reserved for the pathologically inclined :))
So glad you appear to have recouped somewhat. Get strong. Be well. Have fun here. That's the important part.
