Later on in the year I will be having DC2 and I've been told that my KA isn't allowed car seats in the back (something to do with size and impact) so it looks like I'll need to get a new car. Around the same time my parents are emigrating and they've asked if they can keep their car at our house, so they have access to transport when they come back for holidays. They've said that they are happy to swap cars, so we can fit a seat in their slightly bigger one, which is really nice of them.
BUT I'm a little bit worried as they are both chain smokers and have smoked in their car for 7 years now, on lots of long journeys...and they don't worry about putting the window down.
DD1 was admitted to hospital every month for the first year of her life with breathing problems, so I'm just a little worried that being in a car like this could set her off (and that DC2 could be the same).
Am I being mega paranoid? Do smoke fumes linger and could they cause problems? Its so sweet of them to offer to swap so I probably sound really ungrateful!
