I think parenting has been made to be harder, by placing more emphasis on creating perfect childhoods.
Motherhood was fetishised by middle class Victorians with all that angel at the hearth bollocks, designed to keep us in our rightful place. Most women had kids because they couldn't really not, then just had to find a way of keeping them alive.
My grandmothers' lives were hard because they were having to work, whilst having children. They didn't have careers, but every penny counted. Neighbours, mil and older children were enlisted to help. I suspect neither of them would have had so many children I'd they could have avoided it.
My mum was able to be more hands on, at the expense of a decent job. I suspect she had children because it was expected, then just had to make the most of it. But it was 80s parenting, so we were still left to our own devices a lot.
Ignoring the financials for a minute, I think a lot of people are put off parenting because they think it has to be very hands on. I want fully sure with dc1, but I very I unexpectedly felt a massive urge to have a dc2. Like, all consuming need to get pregnant which i didn't expect.
I've adopted a more 80s and 90s style with my own, mainly because I've worked ft throughout, so I've been unable to put my life on hold for them.
