I know this sounds like another in-law bashing thread but I'm genuinely worried about this. They're coming to stay for a week. DC's are 2.4 and 11 months. They go to my parents while we're at work and I have absolutely no worries as they're so well looked after there. IL's however, now want to look after them while they stay but I just don't trust them. FIL is 81 and MIL is 76. She fell down the stairs last time they stayed with us. His Dad likes to drink (starts in a morning with whisky). They love the DC's to bits but are completely not in tune with their needs - there are so many instances when they've stayed with us that have shown me this. DH doesn't really admit to it - I think he doesn't want to upset them. I don't want to upset them either but I'd just be on pins at work worrying. What would you do?
