My sister-in-law is due this week and was complaining to me about her sick aunt coming to the hospital. This got me to thinking about how you handle visitors who have shown up after the warning of "please don't come if you're sick".
I'm also thinking about how my mom hasn't gotten the tdap vaccine but my mother in law, of all unhelpful people, has. I also have a few friends who want to babysit but that I know don't have the tdap. What's the etiquette for this stuff?
