My MIL moved away when my DC was 6 months old, we've seen her basically once a year since.
She stayed with us in our house once for a week, we have her our bedroom, I shared with the DC (2 bed house), DH slept on the sofa.
Most days she went out at lunchtime, and came back late....Drunk.
Story of DH life really.
One memorable evening we'd kept spag bol for her dinner , as she wasnt back for dinner, again, and she screamed she couldn't eat worms, so DH actually dug something out if the freezer and cooked her a whole fresh meal at stupid o'clock at night.
The stress of her being here made me ill, to the point I was nearly hospitalised.
Surprisingly she's never been invited to stay again, when she comes down now, we have her for dinner then take her back to where she's staying.
Oh yes, we also booked a two week holiday near where she lives, and she went away those two weeks...Haven't done that either since!
She's never babysat or given us money........
