In response to your points -
a) I think a lot of women would prefer to work either less, or certainly with more flexibility, yes. This also goes for men. Even for the most career-driven individual (and I know plenty of those), or people who, in all honesty, use work to escape having to be around their kids too much because they find it boring (and I know some of these too) - flexibility and options are never a bad thing. I never met anyone who said "I wish I worked more with less flexibility."
b) Childcare is not 'inherently damaging,' but I don't think anyone is going to argue that babies or toddlers in paid childcare from 7.30 to 5.45 is in any way ideal. Is this really what parents want for our children, on a societal level? High quality childcare is obviously invaluable. It is used in many ways and has many benefits, but, at the more extreme end, let's be honest, most mums would prefer to spend more time with their young kids than 2 hours on an evening, given real choice. Again, it's about reasonable, more child-centred workplace. It may sound idealistic, pie-in-the-sky now, but if people can't even begin to imagine alternative workplace structures that are centred around family life, then how can there be hope anything can ever improve?
c) I do not think that parents working is a direct cause if poor mental health in children. Not at all. On the contrary, I was pointing out how you can never assume or predict anything - but that is things happen, families need to adapt in whatever ways are most practical.
And no I am not arguing that women should 'stay at home.' Far from it. What I am suggesting is that just having a job, in and of itself, does not equate to feminism. Its no longer the 1960s. Most women work in some capacity. Even those who are SAHMs have previously worked and may well return to work in future. But, too often, workplace structures are patriarchal. Women have had to slot into these patriarchal structures that take no account of family life to prove themselves over the decades. But now, I think women should be demanding more. If you are working to the extent you can only see your child at the end of the day for 2 hours, 5 days a week, and you feel perpetually unhappy about this - is that feminism? I don't think it is - it's just women conforming to patriarchy under its latest guise.
