I’m one of those. Serious clinical depression on both my side and my wife’s; if a kid got the worst of both of us it would be seriously Bad News.
i think thats why my oldest did n’t have kids— so much lousy (SO MUCH!!!) on the husbands side, they decided not to take a chance. Youngest did not want kids when she was married, wanted kids after but would not go the single mom route, and now she’s over it.
I have had the grand kid spot filled by my son in laws niece, and it has worked for both of us, since her parents both suck out loud ( OUT LOUD). She is 18 now, no babies, no addiction problems, we did it!! Very proud of her and love her like she was my own.
