We homeschool and two of my littlest had walking pneumonia last spring. We rarely go anywhere other than church and grocery stores. Kids will pick this stuff up no matter what you do.
My oldest caught chicken pox when she was less than a year old and I have NO idea how or where she got it.
I asked around and nobody we knew was dealing with it.
My only guess was the grocery store, the shopping cart handle.
I can’t figure out anything else.
