Still, if there's bugs in the house, it's not likely that Caramello's DH can avoid his own son and avoid catching them.

The thing with compromised immune systems like this is that stuff that most people wouldn't normally catch, we can. To the extent that I am advised to wear gloves when changing my own son's nappy after he has immunisations. Things that aren't a bother for other people can become a huge deal for us.
