Children's Book

I'm mulling over the idea of writing a children's book for the grandbabies. The working title is Fudge Face and the Grey Menace. I have an idea for the plot in my head. I may make this a summer creative project. Any thoughts about what the title might refer to?

I noticed a strange pattern. Every time I spend a significant amount of time (3-4 hours) around the grandbabies, I get a nasty cold. Happened last month when taking them to the Children's Museum and  it occurred again a couple of weeks ago after we celebrated an early Easter. I usually come down with symptoms 70 hours after seeing them. Not having spent a great deal of time around children, I do not have the antibodies to combat their germs. Perhaps I should either wash my hands more or visit them encased in a plastic bubble.
