If you are hoping for wild chicken pox exposure, what is the minimum age at which you would deliberately expose a child?
I would not intentionally expose my child to CP unless they were old enough to articulate to me how they feel.
While CP is generally a mild illness for healthy children, complications are always a possibility and one must look out for them. I think it would be easier to miss a complication should it arise in a child who cannot talk to is too young to really articulate to you how he/she feels. JMHO
