I'm one of five....mixture of boys and girls. We are all now late 30's to late 40's. Only 1 sibling has children. I'm fairly sure the rest of us won't.
Growing up, my mum was a teenage mum, with an older husband. She had 4 kids before she was 24! And then a surprise one 10 years later when she thought she was about to get her freedom back.
I remember so much of her complaining about how difficult it was for her to have to deal with all of these children all of the time. It was very much, my life would be better if I didn't have all these children. Even as a little girl I felt really sorry for her, because her life was so hard because she had so many children to look after.
My father was sometimes frightening, but she loved him , and it wasn't possible for her to leave him, in the 80s/90s and our Irish catholic culture.
So we did endure quite a lot emotionally.
I'm sure that the reason most of us don't have our own children is because childhood was unpleasant, and the parents emphasised how incredibly difficult it was being a parent, and how much better their lives would have been if they hadn't ended up with all of these children.
I actually did want to have children, but I've settled for a cat.....whom I adore.
