Thank you for the response. I agree, I do not allow children to attend who have had fever, an unexplained rash, or vomited in the past 24 hours.
What I am talking/asking about here is probably a very-long cold (that lasted over 2 weeks in December and is now back again) with a bad cough. Would you turn this school- aged child away? Or just allow the child to attend and make everyone sick (because that's pretty much inevitable- air-borne illnesses, particles)?
Not to mention the other 2 wee ones that I have in my daycare that mouth everything.

I clean and sanitize toys, wipe down all surfaces with Lysol disinfecting wipes, each
child has his/her own bed sheets etc. Am I doing something wrong? I vacuum and clean floors every day.

TIA
