I'm almost 38 weeks pregnant with PIH so I've been monitored closely the last few weeks to ensure I don't develop pre-eclampsia. My mil is usually outspoken but doesn't usually step on our toes. She's a smoker and there's been a few times we've gone over to her house and she's lit a cigarette. She doesn't do it near where I'm sitting but will still do it on the other side of the room. I've mentioned it to DH and he said he'd say something next time she did it. When we were over last night for him to help her change sink faucets, she lit a cigarette. He said it bothers him that she's "doing it while his pregnant wife is sitting in the room" and she replied with "I did it around you and your brother when you were babies and you turned out just fine." I was furious and we didn't stay too much longer. I get that it's her choice and her house but I would think that in the interest of her granddaughter, she'd be a little more understanding. DH's dad and stepmom are also smokers but they go outside so that their house doesn't overwhelmingly smell of smoke and so that his stepmom's grandchildren and guests aren't inhaling it.
MIL also said for us to "not be offended but" since my mom is going to be much more hands on when baby is born that she isn't taking any time off to be with us but instead can come over in the evenings if we would like or need help. Which will probably work out better since DH will be home from work by then and I can take a nap, do laundry, or something.
While I'm on the topic, lots of people have bought baby clothes for us (ranging from 0-3 mos up through 12-18 mos) and she laughed at the fact that the baby will probably wear half of them. We honestly don't have THAT much, just enough that I'm sure by the time spring comes, I'll need to buy more 6+ mos. And even if we do, she'll never have to be seen in the same outfit twice

This is the first grand baby on both sides of our family and just bothers me that she was so rude about the smoking. We were planning on bringing baby to her for a couple months when I go back to work in March before summer break starts. DH and I have discussed that the smoking around the baby isn't ok but obviously we need to get her on that page. Otherwise, we need to figure out a plan soon.
Any advice on how to discuss the smoking issue? Just needed to rant a bit. Sorry!
Re: MIL Smoking Rant...
I'm so sorry you are going through this! I had my DD two weeks ago at 34 weeks and I've been constantly worried about her spending time at my ILs since they are smokers and DD is a preemie. Luckily, they only smoke outside and no where near DD, but I would absolutely be furious if they smoked in the house and/or near her!
I don't know if this would help, or if this would be appropriate given the relationship with your MIL, but maybe you could get some literature (a pamphlet or something) from your OB or DD Pedi about the dangers of smoking to give to your MIL?
Sometimes seeing things written on paper makes it seem more "real." My own mother swears that the flu shot gives her the flu, so I showed her the paperwork I got with my flu shot that specifically says the flu shot does not have live flu virus in it.
I hope your MIL is able to realize how dangerous it is to smoke around pregnant women and infants!
In my province in Canada its illegal to smoke with a child in your car. So clearly smoking around children has adverse effects. I don't really know anyone who smokes inside anymore so I definitely think its okay to say if she plans to smoke inside you won't be bringing your baby over there. She can argue all she wants but she will likely change her turn pretty quick if its limits her time with her grandchild.
Smoking sucks. It's dangerous to everyone around it and is just gross. (Sorry, not sorry to anyone here that's a smoker.) My MIL promised that she'd quit if we ever gave her a grandchild. DD1 is five and she still puffs away. -_-

Jan17 Sept Sig: Pumpkin Spice gone too far
My husband still smokes and I intend to put him through a similar ritual when he comes back inside (we've always smoked outside) before he can pick up our son.
And I agree with all the PP, it's your baby and your rules. I would not feel comfortable taking my child to a house where the people smoked inside regularly, even if they smoked outside while we were there. Stay firm and good luck!
