For the record I think I am being totally reasonable, however…
MIL has an active cold sore on her lip. She has already passed the virus to my daughter (I know this as she is the only person who repeatedly kissed my daughter with an active cold sore despite me telling her not too, and now my daughter gets them, and they cause her a lot of pain)
My son (3) doesn’t get them (so far, and neither do I or my DH who is her son - she was clearly careful with her own kids) however she keeps kissing my son with an active infection. I’m horrified, my DH keeps telling me he will speak to her. I haven’t spoken to her yet as we are on holiday and quite honestly every time I bring this up she tells me ‘oh it’s just a little one’ to add to this, she is a GP and it makes me feel stupid telling a GP to stop kissing my kids with cold sores as I feel I really shouldn’t have to.
What would you do and aibu?
