My DPs parents will be meeting DD for the first time soon (they live abroad) and I know they're going to ask to have DD overnight (she's 8 months) on their own but I don't feel comfortable with it at all. I know they're DPs parents but I've only met them once and he's only seen them a few times in the last few years. I don't know how to approach it when they ask without it turning into an awkward argument. They've already had a fall out with his sibling so the sibling is now NC including his own kids.
