I have a problem with the idea that because a man (and it’s not always, but is more often the man) has been at work all week, the childcare and all housework etc falls to the woman 7 days a week.
I think lots of women facilitate this attitude too, that this should be the norm. Lots of women never have a day out at the weekend, never go out in the evening before the kids are fully in bed and do all the cooking, clearing up and cleaning that is required at the weekend. They let/encourage their DH to have a long lie in both days of the weekend and never have one themselves. And this is all justified because the man has gone to work and earned the money. And women push for this sometimes. Often I think it is so they can feel indispensable, and some have martyr complexes, and other believe their DH are incapable with the children or make them so, by never giving them a chance to look after their own children. In other cases this all happens because the man expects it and refuses to do anything because of his week at work.
Even if your DC are in nursery some days and you have paid help with cleaning or gardening or whatever, running the house in the week, is still a job that women largely do. It probably does mean they do the bulk of the weekly work and perhaps a bigger share at the weekend, but it’s not about counting contributions and keeping tabs on who has done most, but being a partnership. A decent DH would want his wife to have a lie-in and a break from some of clearing up etc and would be willing to do some of this and to take the children out and look after them…because they are his kids too and going to work doesn’t mean you don’t have to do anything to look after them.
If a household is lucky enough to have someone at home in the week, it’s a great chance to get most of the tedious jobs of life out of the way in the week, so no-one has to do them at the weekend. There should be time for family time together and bits if free time for all adults. The jobs that inevitably remain for the weekend such as food prep are clearing away can be shared….and the exact ratios don’t need to be pinned down or kept count of.
