I work from home so I see her when she gets up in the morning, I take her to school when it is in session (she goes half-days during the year), I see her during the day for lunch and snack times (my office is by the kitchen). Then right at 5 I stop working and we all have dinner, then we hang out and play. After she goes back to bed at 7/7:30 I often head back to work and work until 10 or 11.
I couldn't imagine having to leave for work before she wakes up and if I hit traffic on the way home not getting home until 6... I would see her a grand total of 90 minutes a day.
Working for myself also lets us do much more, we take more vacations (since I can work a couple days and keep up) and last year we spent 5 weeks in San Francisco.
