We are staying in a group of holiday cottages for in laws birthday party. One child was sick Friday night, yesterday morning and yesterday night. In between its parents and grandparents keep bringing him into the joint area with everyone else. My eldest has now been violently sick for the past hour. I go downstairs in a break from it to get a glass of water and find said child eating cake at the table with his grandmother. I mentioned politely that my son was now I'll and that perhaps her grandson should go back to his own cottage away from the other people. She stropped off with him. I am left feeling like the bad guy. Was I being unreasonable? I just want to avoid the spread to my other child and my two nieces.
