I once found my grandmother’s teenage diary that my dad had taken after her death. I read through it and boy, was my grandmother different than I would have expected! Let’s just say that she was very popular with the boys.
The last entry in the diary talked about going on a date with Kenny (my grandfather) and letting him get under sweater.
Since I was just under 4 at my parents wedding, I guess I was about 5 years premature. ;).
But I’ll have you know that my mother has had sex exactly the number of times she has been pregnant. I refuse to hear or believe any differently.
Damn, you stole my line. Except that I was 11 years premature.
A friend of mines grandmother had her first baby at the age of 15. Her second one at 30 and her last at 45. All with the same husband. Three kids 15 years apart.
Kill. Me. Now.
I’m left wondering exactly what sort of birth control my maternal grandfather’s mother used…he was an only child, born in 1921! And she once confessed that she’d never really wanted kids and was very unhappy when she found out she was going to have one.
It wasn’t until I was grown up that I realized that her having only one child probably wasn’t because she’d had problems having any more, but it’s too late to ask her now. The family consensus is that it probably involved kicking her husband out of the bedroom for about thirty years…we can see her doing that. They don’t make many like her. I miss her.
Oh, and while for some reason I could and still can’t remember the date, I do know that I was at my parents’ wedding. 
I WISH I could do that sort of math.
I would have been conceived early April, late March.
My parents anniversary is late August. Dad’s birthday is early February. Mom’s is late December. So, I wasn’t conceived on any special day, so my parents were obviously having sex pretty often! (Doesn’t help that as a teenager, I saw them leaving the shower together (in robes, so it wasn’t THAT traumatizing).)
But I didn’t come along for 4 years, so I can pretend they were celibate until they were married! (Probably not true.)
Well, if you want to cheat, you can use one of these. 
I am the mother of a 9lb 2oz preemie. (Three weeks early, not six.) I am 100% certain of his date of conception, since he was an IVF baby. Today is his second birthday, and he’s still huge - 36 lbs and 36".
My birthday is June 1, and my parents anniversary is August 29 - I have my suspicions.
A friend of mine in high school was having her 15th birthday party when someone in her extended family mentioned the fact that it seemed they had become party animals, because they had just been over a few month’s back for her parents’ 15th wedding anniversary. She did the math, and realized it had only been 7 months since the anniversary party, and that her mom was only 32, and suddenly all the cylinders clicked into place in her brain. She said she realized then why her mother seemed to resent her, but was all lovey-dovey with her younger sisters. She was the reason her mom’s childhood ended early, but the younger girls were choices she had made.
Erm… 32 is way past from childhood, was that a typo?
Anyways, I learned recently (and mom did too), that her father and mother lived together before marrying. See, we were under the impresion that they were both deeply religious and got married fast.
Turns out they got married because granny’s uncle was getting mad that they were living together. My granny at that time was older than 30, and my grandpa was younger, in his mid-to late 20’s.
The “concern” did help a bit, though, as mom was born 10 months later than the marriage certificate (IIRC).
She’s 32 now.
My uncle was born just over 9months after my grandparents wedding- but weighed 5lbs 9oz.
Since my grandparents lived several hundred miles apart until the day of their wedding and my grandmother is adamant he wasn’t conceived on honeymoon I’m inclined to believe he actually was premature.
