I'll get flamed but I'm vehemently anti smoking, and honestly given you're pregnant and are having to make changes to how you care for your body, plus growing another human and all that entails frankly I think he's being bloody selfish AND he is putting you and baby at risk.
The risks of secondary & even tertiary smoke are now well known he has no excuses.
I'd be expecting him to quit altogether - certainly before baby is born.
At the very LEAST he needs to cut right down, not smoke in the house at all, not smoke immediately before entering car & stick to what you agreed re smoking & coming to bed.
He can go to Drs and get help with quitting/cutting down.
It's also a bloody waste of money - literally burning it when it sounds like you can't afford to be.
If he was previously getting train to work I'd be saying if he smokes just before you're about to set off he's not getting in (your) car he can get the bloody train!

And that's the least scary info I found. SIDS is not the only issue. It is NOT just a case of an unpleasant smell there are dangerous toxins emitted that cling to smokers clothes. Think sbout how you hold a baby, if a smoker holds a baby in clothes they've been smoking in the baby is then breathing in some awful chemicals that we KNOW are harmful to their health.
I'm shocked at the pro-smoker responses you're getting. The risks are WELL KNOWN it's not about op's rights over dh's to smoke it's an INNOCENT BABYS right to a healthy environment that doesn't put them at risk! Baby trumps selfish adult imo.

Third hand smoke risk is hard to research because it's hard to separate it from second hand, if someone's being exposed to one they're likely also being exposed to the other.
Personally I don't think it's worth the risk.
"I wouldn’t worry about any risk to your unborn child, it won’t pose any." You know something the experts don't? At best they say 'we don't know' but most agree there IS a risk with smoking around or exposing pregnant women to the toxins (and that it can happen with secondary and tertiary exposure too).
I agree his attitude in general stinks (pun intended) being a parent is all about compromise & doing what's best for the child and frankly he seems not to give a shit about that!
"I bet you all a million pounds that Wolfiefan smokes or has smoked around children and is trying to minimise it. It's a disgusting, selfish thing to do and anyone who smokes around a child or (even worse) a baby should be utterly and completely ashamed." Totally agree
"Presumably you are going on maternity leave soon so the lift to work thing is likely to change anway" I'd be concerned he's going to drive the car - and smoke in it! The smoke will leave layers of toxins on the surfaces and in the fabric of the seats, which is virtually impossible to remove.
Ok pedro the levels of toxins in the air from things like exhausts is significantly less concentrated than when people are exposed to second hand/third hand smoke which is usually in confined spaces and a car is a very confined space.
I think he's being a selfish dick! As I said earlier it's not op v smoker dh it's baby v smoker dh and I'm on the baby's side!
