Does the whole family have to get sick?

So often when one member of our family gets sick, the rest will follow shortly. This is pretty frustrating, right??

My husband is recovering from brain surgery and two of my kids are sick with stomach bugs!! :/

      

So...as of now, one end of the hall is healthy but recovering from surgery, the other end of the hall is fighting the stomach bug. (and the other daughter hasn't come home from work yet...praying that she's healthy!)

Any tips for keeping the germs to one side of our small house? :) (aside from washing washing washing hands and sanitizing everything I can!)

Prayer. That's what it is, I guess. God is sovereign, He is in control, He will get us through this!

Suggestions welcome, though!! :)
