Oldest kid happened on a trip, though I don’t know whether it was in a motel or at the house we stayed at. For some reason my husband told this to my mom (it was her friend’s house) and she told her friend, leaving out any uncertainty. Thanks a lot, mom. :o I doubt he wanted to know anything about it either.
Kid #2 was at home, don’t know what day.
i)Details please. ducks
ii) Well I know a that I was concieved when my parents were on holiday in the US. Not where and when, but the maths adds up.
I’m not sure if that information will be more or less traumatizing than the other posters who know details of their conceptions. Less, maybe, as the “my parents never had sex” idea will be without a dent.
Look your parents had sex, thats how you came. Its biology.
I on the other hand was delievered by a stork. And no one dare say different. 
I don’t have kids, but I know when and where I was made.
My parents spent only one weekend together in three months, so once they got it through their skulls that yes, they were pregnant, there was no doubt about when and where (my maternal grandparents’ bed, the night before my maternal aunt’s wedding).
SIL is one of those who can tell they’ve gotten pregnant; the first time she didn’t want to believe it until the ObGyn showed her the ultrasound (“but, but but statistics say that on average a couple who’s trying takes two years!” “Yes, which means some people take four years”), but the second time she went “oh… my… uh, darling? We did it!”
No kids, but MammaHomie heard Samba Pa Ti on the radio once and told me, matter of factly, that I was conceived to that song.
However, I think she’s wrong. The album on which that song was released didn’t come out until 1970, and by my math I was conceived in late November 1969.
No. I know where, obviously, for both…in our bed, in our house. But I have no idea which time or what day. We were trying, but not checking fertile days or anything like that. I could pinpoint the month if I sat down with pencil and paper and worked it out, but truly, the day wasn’t memorable. Come to think of it, neither was the sex.
