I’ve been thinking about this and don’t know if it’s maybe that I just move in different social circles now than when I was growing up.
I went to a comprehensive school, mixture of working and middle class families. I was born in 1973. There were no Catholic families as there was a separate state Catholic school nearby, and it was quite ethnically white.
The vast vast majority of my schoolmates had one sibling, as did I.
I have noticed amongst my university and work colleagues that it’s seen as quite normal to have three children and I think perhaps a majority of those who have kids have three. I remember chatting to a friend when her second was born and saying about childbirth something like “well, at least you never have to do that again” and she found it quite odd I’d assume she’d stop at two. She had, and still has, a very successful career (and she did have a third!).
I have no axe to grind, I only have one child myself because of starting late, but I’m fine with that. I find him quite full on though, can’t imagine what it would be like to have three!
My DH is one of 3 actually, and my MIL said that her MIL assumed the third was an accident, which she was quite offended by. DH has a similar economic background to me but comes from the other end of the UK. MIL acknowledges that 3 was unusual in her social circle and 2 was the norm.
Have other people noticed a growing trend for 3 kids or do I just hang out with an unusually fertile/parental crowd these days?
