I am amazed that people are so willing to allow their children to touch only the surfaces that the parents have just coated with a combination of artificial and sometimes hazardous chemicals. They do this rather than expose their children to the same germs against which our auto-immune system has spent millions of years perfecting its defences.
I can see where you are coming from, but surely to worry to this degree is counter-productive for you and your child(ren)? Minor childhood illnesses are not disastrous for your CAH child, they test and strengthen the constitution. We let our guy (2) get on with it.
