These are crazy stories! And valuable because they show a more well to do side than the usual. My experience with adopted and natural born kids being raised together comes from the other end of the socioeconomic ladder. My brother is a foster parent and they specialize in neonates and babies but also have adopted kids and the difference between their natural and adopted kids are pretty minimal. The kids are still young now but I don’t see any difference that would affect future life position outside of chance.
