We eat dinner altogether (most of the time). Usually the kids all go to bed around 8pm but it can take half an hour for both of us to get all four of them down and after that we do dishes (we have a dishwasher but it still takes time), clean up from dinner, I go out and grab some milk and bread if I need to, we give the house a general tidy and we get to sit down and veg sometime between 9:30 and 10pm. DS2 usually wakes up around 10:30 and goes down finally at around 11:30 and we go and have showers and get into bed around 12. They all sleep until at least 7am most days though so we still get 7 hours of unbroken sleep a night.
