Help! I know there are plenty of creative moms on here that can help. My oldest is turning five in a few weeks. We always have the parties at our house. While most everyone there will know my youngest has CF, there will likely be a few newbies from preschool. I am trying to find a polite way to write on the invitations not to come if you or your child has been sick. I know it is common sense, but last year we had a parent who knew my BABY has CF, come with all 4 children who had a nasty respiratory infection. I typically am pretty vocal about this, so I thought I could make up something cute...maybe a rhyme about "please rsvp, but decline if you are sick". My son's party theme is Toy Story. Any help is greatly appreciated!!!
