I had that happen a few months ago. The Dad kept dropping the child off at daycare and telling me the Mom was home sick with the worst cold. The child never got the cold. Do I wish the Mom had kept the child home with her, yes, but could I send the child home just in case he might catch it, no sorry.

Now if the child starts to present with symptoms of strept throat and spikes a fever, then yes I'd send him home immediately. Would you all be exposed already and have a chance of it running through the entire daycare, probably. It's a great business we're in, isn't it?
