If you're the poster I think you are, Kerry (I'm crap at remembering usernames, and never track a poster), you've been through a couple of mills. You know that life generally doesn't work out according to plan; most adults have a few write-offs and re-adjustments along the way.
In a perfect world, all businesses would be intelligently flexible wrt family life. All men and women would take equal responsibility, in real terms, for their children. Everybody would be able to put the pieces together in the best possible way for everyone involved, and all children would get the best possible care in their particular circumstances.
In a broad sense, this is what feminism offers and fights for. I sometimes think it shouldn't be called 'feminism' any more ... but the truth is, we still live in a man's world and it's going to be quite a while before men appreciate the benefits of what feminists call for. So it's still up to women to push forwards, they'll come on board when they get it.
Meanwhile, we've still got women who bear children and children who don't develop according to business rules. For as long as adult lives are dictated by the rules of men's businesses, it's impossible for children to fit perfectly into it (or ageing parents, sick spouses and the rest.) So - for now, we have to wriggle around finding compromises that work as well as possible for our dependents.
There are a lot of parents who are not 'natural parents'. I suspect that isn't divided by gender, tbh. I've seen a lot of couples with a more 'parenty' man, who has to do the nine-to-five because he earns more and wasn't compromised by pregnancy. I've seen a lot of women going barmy with having to speak in two-syllable words for six years and, if I'd had kids, I would have been one of them.
Have you ever thought that - just perhaps - the high levels of women with depression might be connected with the high proportion of women forced into full-time mothering by the economic realities of our male-pattern commerce? How many of them have partners who'd be happier parenting than them, if commerce made sense of it? How many are too depressed to engage fully with their kids, and would be happier at work while their child had a better 'parent', biological or professional?
Do kids still have "The Wheels On The Bus" these days? I literally started hallucinating on the hundredth repetition of that song! Lucky I had training. Some women must feel they've totally lost it when that happens. They shouldn't be forced into that position :(
