Hi Amanda, I feel your pain. I have had similar issues with my mother and her smoking habit. The kids would come home and their entire clothing, stuffed animals, suitcases, everything smelling like a smokestack. And my mom is the poster child for smoking. She feels like she is entitled to smoke where ever and whenever she pleases and I am a total snot for even commenting on it. It's a very selfish attitude. I don't care if she smokes (well I do but we won't go into caring about her health, etc), I just don't want for us all to have to share it with her. With that said, she can smoke in her house on her terms, so I just unfort. do not make an effort to have the kids stay with her, sad but true. I do not want my kids breathing smoke if they visit her. You have a sticky situation there. I would either plan their visits to your house where it's not as habitual and they can easily go outside, or plan alternate places to stay while you're there. The first couple of times you are in a hotel because of their smoke, they may just make the necessary amendments to have you feel comfortable there. Unfort. the addiction is stronger than being unselfish, and they may get defensive, but don't put yourself through years of misery. Set your boundaries now in a gentle loving way and stand up for your rights with this. When you have your own family, you have to do what is best for them and you would think that grandparents, at their age, would have good judgment. It is absolutely miserable trying to stay with two smokers, I totally understand this. Good luck...
