Would I make a neurotic frankenkid?
Being slightly neurotic myself, I too have thought about this stuff. However the thing that makes me stop thinking about it is realizing that my parents are total opposites, personality-wise, and instead of having created two children who are a mixture of their two personalities, they created one kid (me) who very much takes after her father, and one kid (my brother) who very much takes after my mother. So it’s really a crap shoot how this stuff works out. And plenty of people I know don’t take after their parents whatsoever. So just marry someone who makes you feel emotionally stable and “sane”– that’s the best way to encourage emotional stability and “sanity” for your kids.
