With parenting though, I think another reason people are looking for answers is that we've become cut off from a tradition of parenting or childrearing. Smaller families, people move away from grandparents, communities are mixed and people don't have the same way of doing things as their neighbours. Lots of people have a child and have never really spent any time with children, the whole thing is pretty new to them. And then the way of life people have, with both parents working, being pretty isolated, and so forth, means some of the ways people used to do things won't really work any more.
So much of this has become about the marketing of parenting and I agree that its linked to mothers having to start from scratch because there's been a loss of background / cultural knowledge about how parenting works due to smaller nuclear families etc.
I think this is very sad, and rings true.
There is a lot of active resistance towards how previous/older/our mothers' generations did things. We are reinventing the bloody wheel with every child, rejecting our traditions, cultural knowledge, community consensus, general advice. I wonder why?
A huge absence of trust. I certainly felt this with my 1st child. With my 2nd, I was far braver about asking for help, didn't feel that I knew - or should know - everything, had a great understanding of how imperfect and failure prone myself and everyone else is.
But with my 1st, it was like landing on the moon with a newborn and a selection of books with strict instructions. One of the books would lead to establishing a successful community on the moon and continue the human race, the other book would explode us all in an agony of physical and mentally damaged failure. It felt like everyone was there to judge, rather than help - doctors, midwives, health visitors, other parents. And nobody agreed with each other. The most isolating, pressured, and difficult experience of my life.
