We live in Asia and they are from England. They usually come quite often, 3-4 times a year especially MIL, she stays 1 month at a time and when my baby's born in August they will be here for a month

My OH said to me if that's alright. I said well, what do you want me to say, they already booked the flight.
And i really don't want them here. i have enough stress already now and she always goes on about cleaning ( all day long every day ). Every time we have to have a big cleaning the day before she arrives and it's never been cleaned enough for her. And she keeps saying things she doesn't want us to do with her grandchild : like using the ( baby ) pillow, using talcum powder because it's dangerous, bla bla bla and all the advise that make me want to leave the house: do this do that, do it like this like that, have you done this or that,........

it's gonna be a real pain. I know how to take care of things here and what i want to do , but it's always like "this is better" or "This will be better for you, believe me"
