Well, Kayla, you know I'm an old geezer compared to you.
And even with my last pregnancy I was still older than you are now.
I can sympathize about your mom's reaction. I have always dreaded telling my mom. With the first one she was distressed because my husband and I are interracial and she had a hard time coping with the idea of a biracial grandchild. Fortunately, she got over that pretty quickly. But even after that, her response to me being pregnant has always been less than enthusiastic. A couple of times the initial response was, "I'm sorry"
and this pregnancy definitely was not a happy announcement to her because of my age, in part. But she was 37 when she had me (her last) so it's not like it's a totally foreign concept to her.
Partly, though, her problem with me is because I'm a firm believer in natural childbirth and she can't stand what she sees as me "bucking the system". Like your mom, she's elderly, and in her day, that kind of thing just wasn't done. She also isn't really a kid person, which is kind of hilarious since she had 8 of us.
Anyhoo, I'm just glad that you are in such an emotionally healthier situation with this pregnancy and can enjoy it!
