Both. Usually DH will prep stuff, then I'll cook while he plays with DD, then we'll serve up. After dinner we'll put DD to bed, then I'll unstack the dishwasher while DH cleans the mess in the lounge. Then we'll get some quality time in together. I go to bed before DH, and he stays up and cleans the kitchen, sweeps the lounge and kitchen, loads the dishwasher and opens all the windows/just generally makes the house lovely and tidy for the next day If we have a cooked brekky (once or twice a week) DH will cook.
