When will family take this pandemic seriously?

I live with my parents, my mom is an essential worker. She works at a grocery store. I have asked her time and time again to shower as soon as she gets home and change her clothes because she’s working with the public. She came home today, walking around the house. Going up and downstairs, I said to her can you go shower and change. You shouldn’t be walking around the house in clothes you’ve been in the public with. Especially having a baby here at the house. And she freaked out on me..... like she isn’t taking this shit seriously at all. And then what happens if my baby gets sick? Is she going to feed bad then. It’s ridiculous. My mom works with the public, my brother works at a nursing home, so they’re both around germs all day long. I’m afraid of my daughter getting sick. It’s ridiculous
