For the first couple of years with my daughter, I coded on the weekends. I timed it for one of her naps, because she had a pretty solid routine - 2hours sleep 2hours awake during the day time. I timed everything though, and limited myself to 30 minutes at a time to make sure I got to my share of the chores and got enough rest myself. If you plan carefully, you can be very productive - try something like the pomodoro technique to make sure you aren't just faffing about. Evenings after work I found it better just to enjoy time with my family and get some exercise and rest.
