This is from another carer:
Mary had a little cold, DIDN'T STAY HOME everywhere Mary went the cold was sure to roam It wandered into Molly's eyes filling them with tears Jumped to Bobby's nose then to Jimmy's ears painting Annie's throat bright red, swelling poor Johnnie's head, Dora had a fever a cough put Jack to bed The Moral of this little tale is very quickly said

Mary could have saved a lot of pain with just a day in bed
I really like that!
