I will try not to bias this with too much detail, so in a nutshell.
Relative comes to stay with their partner and a 5 year old (not their child, another family member).
Living in a very small house with disabled kids who can’t be moved out of their room, I offer the adults our bed and buy an inflatable child’s bed and sleeping bag to go on the floor next to their bed, and DH and I sleep on the sofa.
It’s our wedding anniversary and the guests kindly offer to babysit so we can go out for a meal for the first time in a year - amazing, super grateful.
Get home. They go to bed. We sleep on the sofa.
Next morning visitor says the little one has had an accident - no problem, that’s what five year olds do, which is why I bought a bed that’s machine washable.
Oh no - she slept in our bed, but it’s okay because she’s stripped the bed, it’s no problem. I was rushing one of my kids out the door to a hospital appointment so I just bunged the sheets in the wash and left. No more was said.
Got home, relatives leave and I go upstairs - our new and expensive mattress is soaked through with pee, as is the duvet which has been left on another part of the bed causing another wee patch.
I’ve spent three days now trying everything I can to get the wee out and it’s not happening. It stinks. Our room stinks.
Relative has said nothing about it at all. If it were me I’d be mortified and asking what I could do to fix it. This has annoyed me more than the accident - although that’s super annoying because it could have been avoided by just putting the 5 year old in the bed i bought for her. She never even lay on it, she was put straight to bed in our bed.
AIBU to be so bloody annoyed? I am going to try and find someone to professionally clean it tomorrow but will probably need to replace it.
