And IIRC the rate of false paternity is *of those tested*, not overall. Which self-selects to guys who had doubts.

There are ways to ask that aren't "I accuse you of cheating" -- e.g. "I keep hearing stories of babies switched at birth, I know it's a largely irrational fear but I'd like to make sure we have the right baby" -- but it needs to be broached as a topic of discussion before any pregnancy happens.

And I struggle with the idea that raising a child you aren't related to is somehow wrong. I get that cheating is bad, but LW says it isn't about that.
