Changing operating hours

Do any of the existing clients need until your current end time? If not, than I can't see why it would be a problem

No they don't technically "need it", but use it for running errands after work. I have one going on mat leave beginning of Jan. so that was my later pickup(older child will still be part time)I figure that's a great time as she can't use the work excuse for the later pickup. It's about 15 mins of time they actually use, but 1/2 hour earlier than posted on paper. The other family typically picks up by my new proposed closing time. My 2 new families have shorter operating hours in their contracts.

I wouldn't worry about it too much. I don't think many, if any, parents would leave a daycare that is meeting all their other needs just because they can no longer run an errand at the end of they day. If it was an hour or more I could understand but for 30 minutes I really don't see anyone leaving if they don't really need till than anyways.

I'd give 1 month notice too. I would tell them beginning of December for the start January. Personally if one of my long term parents came to me needing an extra week or 2 to sort it out with work I would go with it. I have friends who I know need 6 weeks to change there work schedule.

And definitely don't drop your rate. If they mention it. I would say do did it this way in lieu of a price increase.
