PIL live some distance away, SIL lives near to them so they see her and her DC often. Every time we arrange to visit PIL, she hijacks part of our trip, persuading PIL that it will be boring for our DC at their house, and that we should stay with SIL. We always arrange to visit SIL during our visit, but that is never good enough for her.
AIBU to want my DC to have some quality time with their GP without their cousins?
I have caught her out in a lie before, when she called us before our visit to say PIL are panicking about food and space, and suggested we would be better off staying at theirs; when I spoke to FIL he was horrified as he had said nothing of the sort.
I am more than happy to spend some time with them, but I know she wants my DC to 'entertain' hers, no problem with that, but not to the detriment of the relationship with PIL.
