Mattee,
You get my vote for common sense. Your son will grow up just fine. You cannot pretect yourself from exposure to everything that might be bad for you. You are better off to learn to live with it gradually, and build up some natural immunity. When I was working I rarely took off time for illness. When I retired the employer paid me for the maximum hours of banked sick time. I spent that money on the latest computerized sewing machine. I just don't do sick.
