I genuinely don't know so interested to hear views...
DSis is getting married in 10 days. I let her know yesterday that DS1 has chicken pox and although he is already nearly over it and will be fine by the wedding, DS2 hasn't had it yet and she might want to tell any pregnant guests to steer clear of DS2 just in case he is incubating it (we would obviously also keep him away from anyone obviously pregnant). DS2 has now been 'uninvited' from the wedding.
I have told her that's fine and reassured her that she must do what she is comfortable with for her wedding etc etc but was a little surprised. Is it normal to keep siblings away from the public until any danger of them having caught chicken pox has passed?
