DH works away Tues-Fri and I work a 25 hour week. I would say the cleaner does the majority of the actual cleaning. I do all the other household chores of cooking, shopping, washing, tidying. He does the ironing, will occasionally take the rubbish out, perhaps doing the washing up twice a year!
We both pay equal amounts of household bills so it's not about me "paying my share" with housework, it's just that I have more time than him and I wanted to live here in a nice house rather than in a pokey London flat. Plus I'm better at it than him
. He in turn does a rather grim commute twice a week which he finds quite stressful.
In terms of childcare, I'm sole charge for Tues-Fri so he pretty much takes over responsibility Fri-Mon so I have some time off. That I think is important, because otherwise you could end up feeling resentful that they swan in and just do the fun stuff and then leave you to deal with all the crap.
I also think it's quite important that I'm not a martyr when it comes to the kids - we have lots of help from Granny and childminders too.
