Anxious

There is a tension between the person who takes care of my child since I asked her a question. Since when I write to her to inform her of the absence and other I receive only silence. When I go to pick him up I often feel like she is being forced into a conversation, sometimes I hold back so as not to get into a conversation but she tries to talk to me. My child has had RSV for 3 weeks and is the baby of the group of children she babysits. She always defends herself by saying she doesn't have a virus, when I was hoping she would understand that my baby is 7 months old and it's normal for him to get viruses. I don't know what to do anymore. I have no one to help me. I thought I had a good relationship with her because she takes care of my child and I would sometimes bring her a Starbucks to show her how much I appreciate her work. I really don't want to see her anymore because she makes me uncomfortable when I ask her a question or tell her my child has caught a virus without her getting defensive.
