We need a quarantine sign on our door

Grant came home from work on Thursday deathly sick, and about an hour after that I got sick. Mason was sick as well. I went to work today, and when I came to get Mason at the babysitters, he was really bad. My babysitter said Mason sounded like he had croup. We talked to a telehealth nurse and she suggested we go to the emerg. He does have croup, and boy it's hard to deal with. He is so hard to get to sleep and he keeps waking up.
