I have a friend that's due to visit today for the weekend. However, she's just let me know that she and her baby spent time on weds with a baby who has now been diagnosed with hand, foot and mouth. They didn't touch but may have shared a toy. I'd be gutted to cancel but I don't want my 1 yo to get it and she won't want to be away from home if her 7 month has it. Should we risk it or cancel? what would you do?
