I'll admit and say that ive been rung up because Lily or Charlie has the runs or is sick. But they were perfectly fine when i dropped them off. Sometimes sickness just comes on very suddenly. I do make sure that they are better for a good 3 days before i send them back. It is a PITA though to have to pay even if they arn't there. Sending your child there while they are obviously sick at the time though is wrong.
