As a stay-at-home dad with twins, I spend about 2 hours a week shopping and probably an hour a day on average on housework. We cook lots once a week and microwave it; I run the dishwasher every day and do laundry perhaps 3 times a week.

Of course I spend a lot of time with the kids, playing, dressing them up, changing diapers etc. All day basically. But that's more like hanging out than housework.
