We've been invited to dh family for a meal and I'm not sure if I really want to go. Mainly because when we usually go there, at least three members of his family smoke indoors, to the point my eyes are stinging. 23weeks pregnant and don't really want to put my unborn child at that kind of risk, any advice on what I should do? Oh has already explained I won't be going but he's going to go alone and now I feel a bit guilty. I'd rather not go though than ask someone not to smoke in their own home.
