Sorry but have to rant

So basically I'm living with my mum till may and I asked her to stop smoking in the house because my room is next to the room she smokes and also it's the living room I don't want my baby inhaling all the smoke ive told her for months to stop my due date is 13 days away and she still hasn't stopped and I know it's her house but come on its her grandchild and she doesn't have the decency to stop she said Thursday she will stop but it takes a month for a room to clear of smoke im so angry I dunno what to do and what if my baby comes before thursday ?? If my baby has any breathing problems it's gonna make me blame her because of the smoke
