@joyathome My sister has two, we are OAD. She said it made her sad to think of her son being an only. They thought about a third, but she feels done, though my BIL doesn't. I hope my sister puts her foot down and doesn't have a third just to make him happy for a multitude of reasons, but mostly that I think she feels their family is complete and it should be both their decisions.
I literally cannot imagine being pregnant and having a baby again, and our son just hit 6 months. I had a miscarriage about 8 months before getting pregnant with him and I think about that baby every day, but I also think about the fact that had I had that baby I wouldn't have my son today. I finally brought up to my husband that I'd like a ring or necklace with both birthstones (our son's, and the one for the projected due date of the one I miscarried) on it for Mother's Day because I am a mother of two even if I only got to see the one.
I've been told by doctors to wait until our son is a year old for my husband's vasectomy "in case something happens," but I wouldn't want to have another baby if something did happen. I wouldn't ever have a "replacement" child if something happened to him. I might be open to fostering or adopting once I felt I could survive again if we lost our son, but I honestly do not want more children.
I think you just know. I understand there are fencesitters, but I think deep down they know and maybe haven't fully accepted or grieved the idea of the family they had in their mind versus the reality of what their family is. Even when we are happy with something and want something, I think feeling grief and grieving the previous idea of the thing is healthy and normal. I've had to do it a lot in my life.
