MIL has taken offence because I won't let my DC go to her house, the only time I ever let them go is in the summer when we can go into the garden.
The reason for this is that she and FIL are heavy smokers and although DH has hinted that we would visit more if she and FIL smoked outside we know we are being unreasonable to ask them to do this as it is their house and if they want to smoke inside then it is their choice. But I don't want my DC in a smokey environment especially as 3yr old DS has asthma.
She now says I am being difficult and that i'm doing all I can to stop her from seeing her granchildren. This is not the case I have told her she can come to our house whenever she wants.
I'm not anti smoking I'm just anti smoking around my DC. I feel guilty for upsetting her but I can't see what else I can do.
