Too late now, but chickenpox vaccine would have protected the child!
Most adults have had chickenpox, and will be immune, so someone can mind the child during the wedding. Adults can NOT catch shingles from someone with chickenpox, but anyone who hasn't had it could be vulnerable.
Unfortunately, adults can catch chicken pox, even if they have had it as children.
I had had chicken pox when I was three, and contracted it again 25 years later when my 2 year old niece who was staying with us came down with it. I was dreadfully ill, which was unpleasant but bearable, but I passed it on to a dear lady, I had known since childhood, who was dying of cancer at the time, and really did not need chicken pox as well.
I had visited her for the last time before I knew I had chicken pox.
So keep that child at home.
