I know what you mean. A dcMom wrote to me this afternoon telling me that she had the flu from last Friday to Monday and just went back to work today. I didn't have a clue because the Dad drops off and picks up his daughter here and didn't say a word. Today the little girl wasn't herself and had red cheeks and red rimmed eyes and I'm very, very afraid that we're all in for a flu epidemic. I hope not!
But OtherMummy, you are right, there isn't anything you or I could have done if we had known before instead of after. We can't turn healthy children away at the door because we're afraid. It's part of the business and part of our promise to the parents. Good luck to both of us!
