Anything that messes with the schedule for the day disrupts the day for everyone. I would probably insist that the child comes in the morning at the normal time so I know he is still on the same food/sleep need schedule as the others. Then if you wanted to do an early pick up it would be before lunch so that I have the lunchtime to get the others resettled for the rest of the day. If he is coming all morning it would be just as easy to leave him for naptime too and then pick up as soon as naptime is over so a bit earlier pick up than usual.

It is important to know what our schedules are going to be like. Many plan events out in advance and need to know. Does she go to playgroup on Mondays for instance and plans outings on days she knows she will have less children. Does she plan a curriculum and crafts and have the units planned in advance so materials for monday are cut more than a week in advance. Mostlly our days are stressful enough and starting out the week with a change isn't always easy on anyone.

If the child has been in care for over a year then it should be a bit easier to accomodate the one day change but what you should consider is child either comes or doesn't and not do the part day. As others have said while your child might not have an issue with it, others in care might. A parent showing up at the door signals go home not go to bed. Once your child has gone home the provider has to try and explain to the other 4 why they have to go to bed and not wait for their parents to pick up since it is still a few ours away.

As for the not working and paying anyways so why can't you use the day I have never understood that one. People pay someone to watch their child for lots of reasons and as long as you can be reached wherever you are I don't see that why you need care should matter but it does for many.
