In my contract it states any discharge coming from the eyes or ears is not permitted in daycare and yes they have to be symptom free for a min 24 hours before returning to care. I am more lax on the green runny noses as most of my kids would be absent 75% of the time. I have never seen so much green snot in my life as I get from a couple of my dcks. Fortunately all my parents are good about keeping their kids home when they are really bad. I also get paid up front for the following two weeks so not paying is not an option.
