Daycarelady, my official hours are also 7:30-5pm with a maximum 9 hour day and $5/half hour overtime or early or late fees. I'm really lucky that my clients right now arrive at 8 and are all gone by 4:45pm. I love it and I'm not exhausted the way I used to be in my first 3 years where my start time was 7am. The extra hour in the morning has made a huge difference in my health and sleep. You also have to watch out for the clients who say they want to start at 7:30 and arrive at 7:15. You have to tell those clients that is not allowed.
