I too start early (6:45) and therefore finish early (4:30) but it is still almost 10 hours and I did exactly what a previous poster said ... I gradually cut back my hours as people moved on but if you don't have anybody leaving then you should just post a notice saying that effective xxxx (what ever is required in your policy book for changes) that you will be closing at xxxx. Sometimes people can have one parent drop off and another pick up in order for the child not to be in care that long and sometimes people leave their kids in care to closing time so they feel they got their money's worth .... In my policy book anything over 5 hours is full days.
