Arg! Our family caught the flu. I'm not surprised - my brother-in-law and nephew have it, my sister and her baby have it, a dozen people from my husband's office are out sick as well.
Several of the kids have caught it, but it didn't last long, and they were over it quickly.
Besides lots of rest and lots of fluids, we also give the kids Scientology assists and use the information in Scientology Volunteer Minister's Handbook - The Cause of Suppression.
This helps a great deal, actually.
We are fortunate that the kids don't get sick often - but when they do, we like to handle it quickly and efficiently! No kid wants to be stuck in bed!
