I didn't quite make that - had my first at 33. But all our family are "slow begetters like", as Kipling said in one of his stories - my mom didn't have me (her first) until she was 30, which was VERY old back then.
I took tons of folic acid because since I'm almost 100 percent British ancestry I'm at risk for neural tube defects. My OB (he was the best in the world until he died last year, so I guess Grace's OB has the title now) had a brand new ultrasound (ya gotta understand this was 17 years ago!) and he loved to play with his new toy, so we checked my girl it seemed like every five minutes. He was confident that he could pick up any neural tube problems from what he could see - loved pointing out to me that her kidneys were functioning, her bladder was filling nicely, assuring me that that was an almost infallible sign that her spinal cord was developing properly (of course all I could see was a blur . . . they've improved ultrasound a lot.) He charged a flat rate per delivery, so he could play with his ultrasound as much as he liked - I have a lot of funny blurry pictures in the baby book . . .
Of course baby was born perfectly healthy, if quite skinny. She's still quite skinny (thank heavens she took after her dad's family and not mine - we are all fireplugs).
In the lingo they're called geriatric primips;)
I have to sign off... she's definitely in labor. The Castor Oil totally worked.
Will give an update in a few days...and thanks to all for the kindness and well wishes.
I had my first at 35, so put me in the Geriatric Moms category. But my mom turned 39 the day before she had me. My maternal grandmother had 12 kids, and I think at least one or two were "change of life" babies, I think they were called. I believe she was in her early 40s when she had them (and this would be in the 1930s). I do think genetics plays a big role in all of it.
