I agree with the other ladies, keep breastfeeding, it will help her through it if she does catch it. You’ll both be fine, keep drinking plenty and take paracetamol regularly xx
Personally I would keep feeding, treat it like I would any other virus. She will get antibodies from your milk :) I know ideally you dont want her to get it, but the chances are you've spent all of your contagious period around her so she has already been exposed and your breastmilk will be so good for her if she were to come down with symptoms.
