I'm not grasping at straws. She has made many comments like that and I'm sure the children will have some weird feelings about it growing up. My DH was a "mistake" as his parents say and it still bothers him to this day and that is only said around family. He always says "why can't they just say happy accident". It bothers you when you feel your parents weren't ecstatic to find out you were on the way.
I have two kids. What does that matter? They put themselves out there to the public. They have to accept the good with the bad.
I think you are getting a little harsh with people that don't agree with you.
Doesn't bother me and my mom said when she found out she wanted to stop and buy a gun and shoot herself for being pregnant again. Now that being said, they made it clear after that they they were very glad to have me, but also made it known that I was in no way planned and not wanted at the time of conception.
