My partner's elderly father is living with us at the moment, this is likely to be the case for several months. He smokes but in the garden outside the house. I'm pregnant and due next month and extremely worried about the potential impact on my baby. I've asked my partner to discuss at least having a coat he leaves outside or something when he smokes so he doesn't smell of smoke when coming back in. He also has an uncle who smokes who visits a few times a week, I don't think I can ask him to bring a coat and not sure how best to approach this...my partner has assured me he'll speak to them both but still hasn't, is it better for me just to approach them both directly at this stage?
