Ah, I didn't say it was all jealousy between the kids or of the kids
There are some pretty big gaps in intelligence among the sibs in my family (children of my parents). And then throw spouses in the mix, who may or may not be gifted. So we do have a mixture at the parent level of gifted and not. Also... we sibs have one very bright parent and one just average... so the genes were not spread evenly, I suspect. We definitely don't fit the 10 point IQ point range theory for the sibs.
So some of the treatment of kids may not be about the kids at all in some families, but about things still playing out from the parents' generation. It is still misguided jealousy, but not always easy to solve.
