This has been bothering me. It seems people by and large have their nannies and babysitters back in their homes. How are you all getting comfortable with this? Surely they aren't wearing masks. And surely they can't be in a "pod" with you unless they are live-in, right? I had some nannies I knew well, but I never really knew their home life and what they did when they weren't in my home. Can you explain how this is not risky?
