I do before-school care for several children and I've been known to keep sick kids even though my own children are in school for the day. Depends HOW sick they are of course. I've kept kids with lice, kids with colds, kids with strep, etc. I don't keep vomiting children and anything that could seriously make my own children ill like RSV(I have two asthmatics) or whooping cough. But the more minor stuff I have no problem with. I'm sure if you look around(try care.com) you can find sitters willing to take drop-ins for sick kids for only slightly more. I charge extra of course but then again, I typically only do before and after school care and have no kids during the school day.
