Nothing.
I work 3 days a week, so I am out of the house at work or travelling to/from work for 30 or so hours.
DH works 5 days a week, and is out of the house (at work or travelling) for 60 hours a week, at least.
I simply have more time at home, though, granted, I am looking after DC2 on the 2 days of the week that I am not working, as well as ferrying DC1 to/from school, clubs, playdates etc and doing before and after school care.
We have a cleaner who also does our ironing.
On weekdays, I do everything in the home and for the DC including cooking, laundry, putting bins out, homework and reading with DC1 etc.
At the weekend, DH and I share most tasks which works out as him doing anything garden or DIY related, and me doing more of what anyone would call traditional womens work like cooking, laundry (seemingly endless), dishwasher, tidying (endless). We take equal responsibility for the DC at the weekends.
