At the age of 6, I informed my mother that I was never going to have kids. Of course she didn't take me seriously.
I'm 50 now. Guess what, no kids, and very pleased with that. In the distant past, I've had mothers of partners ask me, "When are we going to hear the patter of little feet?" (Oh, vomit!) And, "Are you going to give me any grandchildren?" (Not $%#@ likely!) And most of the time, I think, why the heck would I want to jump into your gene pool? And why would I want to produce offspring that will be screwed over by your lackadaisical grandparenting?
One partner went back on his statement of not wanting kids, but I prefer to think now that he had his eye on someone else anyway. No great loss.
Babies frighten the bejesus out of me anyway. Unpredictable, grinning, screaming little horrors. They are definitely in the region of Uncanny Valley. But I'm getting better - I can actually hold one now.
So, it's a GREAT RELIEF to hear that, although I may not be typical, I'm not alone. Thankyou, previous posters.
