Hello, first time posting here, glad I found this community! Title pretty much says it all, my nephew got me pregnant and we both wanna keep it, but since he still lives with his mom and I stop by a lot, I’m not sure how to be honest with her about it. Also, are there any major defects that come with first generation inbreeding? Or anything later? My nephew says he wants to start a full “incest family” with our kids in the future, what complications would that have? Thanks!
