Unfortunately, if they have "common colds" it is hard to force parents to keep them at home, even if their noses are running or they are constantly coughing. What you might go is encourage the parent's behaviors though suggesting when it is appropriate to keep their child home even if they don't have a fever.

My current Sick/Illness Policy does have verbiage to encourage parents when it might be a good idea to keep their child home. If you would like me to share, just send me a PM with your email and I can forward you a copy of my policy.
