If my own child is sick I normally don't close. We just cope. If it is the first of the group to get sick I will call parents in the morning and give them the option of coming or not. More often she is near the end of the group to get sick and the others have had their chance to be sick as in they got it from them. With my school age kids they would normally spend time on the couch in the family room and that room is generally off limits anyways other than for tv watching.

My attitude is that I operate a family home daycare meaning during the day I had 9 children in my "family" $ own + 5 daycare and sometimes one or more of them would be sick and we just carried on the same as if one of them was teething and fussy or whatever. I never really separated my work as a mother from my work as a daycare provider it just meshed into one so during the day I sometimes had my own sick kids in the daycare mix or nearby but as far away as practical from the mix. And some days my hubby was home sick or there were days I wore an apron with big pockets for kleenex so I could cope and didn't bend over any more than I had to.
