My daughter’s father insists on sending her to school when she is with him every two weeks. When she is with me I teach her from home. She was getting over a cold when she went back to her dad’s and he made her go to school in a mask for 9 hours a day. During that time she developed an itchy rash around her mouth that lasted until she came back to me where I don’t ever put her in a mask. It got better each day she was with me, mask free, until finally gone.
