When i was near term - no one would come near me with a cold.. they would call and we'd chat that way (not the same i know) and if anyone has a cold now, they won't go near bubs if we see them down the street etc, and they won't visit with a cold... (not that that has stop izzy and my self getting them)..

i don't think it is rude to ask him to stay away... when it comes to health matter, you do what you feel is right...
