I put my early arrivals back to bed when I allowed early drop off.
If not the kids were all on different schedules all day.
Breakfast is at 8, so now I don't open until then.

It also shows you how to add kids.
It takes a few minutes to get the hang of it, but once you do it goes quickly. I do mine a year in advance, Rotating Menus..
Simple.
