Our baby is 4 days old today and has had a few close family visitors. My MIL said she is picking her mom up at the airport and wants to come by here next week with her since it's on the way home from there. We would love for her to meet her 20th great grandchild, but my husband and I are uncomfortable with the fact she's coming from the airport with nasty germs. We don't know what to say, any advice on what to say? I'll probably have my husband tell her, but he was like "what excuse do we use?"
