From reading everyone's responses it seems that we're pretty much all appalled that your client seems to be misinformed on how the daycare provider/client relationship should work. However, I think you set the precedent by washing her child's soiled laundry and accepting the issue of no pull ups at naptime. If she was truly respectful of your business relationship she would have brought the extra clothes and suggested other ways to avoid soiling linens, etc. such as the plastic bed liners. I would nip this in the bud now. I would firmly tell her in no uncertain terms, what you expect and stick to it. If she has a problem, give her notice. This client does not sound promising.
