I don't vape around my grandchildren. They are small and I'm usually holding them or playing a game with them. If they are visiting our place I go to another room etc. If I am at their house I go outside just as I did when I smoked analogs. My son and his wife have never smoked so wouldn't consider vaping inside. I think the correct thing to do is ask and respect the home owner's answer. When our family is all gathered at my parents, both my father and I vape inside with no complaints. The rest of the family commented at Christmas how nice it was to play cards with us vaping instead of smoking in the same room
