Hello,A family member would like me to find new childcare for my children because she believes the dander they pick up could be making her sick. My provider has one cat and my children are there from 5-10 hours per week. This family member does not live in the same house as us, she never picks them up from childcare, and my children never go directly from their babysitters house to my sister in laws. We do not own a cat at our house, have it professionally cleaned twice a month, and store all our hats, coats, boots, and shoes in a mudroom directly next to the entrance of our house. We have no carpeting in our home. We wash all our clothes and outerwear before we see her. My children's friends have cats so there is no way for us to be totally cat free. We see this family member maybe 1-2 times per month. We suffer from well controlled allergies ourselves and are not convinced firing our well liked sitter will solve this problem for this family member. Anyone have any thoughts?
