"i am saying it isnt beyond anyone to cook a meal do some chores and have time for self and baby over a complete day"
And I'm saying that it's not beyond me, but that I couldn't be arsed with it.
Why should I do those things just because you think they're what women should do on top of caring for their children?
I'm mentioning the 1950s because your ideas seem to be pretty much the same as my Granny's, although she had a much different idea of fairness and would never have stood for being taken for granted in the way that you think is right for non-working parents.
"eeding help to pitch in with what's left or needs doing in the evening, e.g cooking dinner, washing up, making lunches...well thats is indicative of not managing a minimum chores over a prolonged period"
OR it's indicative of not prioritising those tasks, NOT considering them to be a minimum.
I'm very unlikely to ever give up working because I love my job. But if I should ever find myself in a situation where I am off all day with my children, I will not be taking on extra housework responsibilities.
Some days I might take it upon myself to do some task that I'd like to get done, or that I think DH would appreciate having done, but other days I might well be too busy either with my children, or doing my own stuff.
No fucker gets to come home from work and make me answer for what I've been doing all day. Not that DH is that kind of dick anyway. He found it hilarious when I started ironing his shirts when on mat leave. Couldn't understand why I was wasting my leave doing something so pointless that he's well able to do for himself, and always has.
