My SIL and her brood of four are expecting to come stay over half-term again. I find her very overbearing, though her partner and the kids are lovely. None of them, except the much put-upon partner lift a finger to help.
It's a few hours on a train for them and despite this last year I asked them to come for a maximum of four nights as it's quite a houseful and full-on, and not half-term for us (though my two kids love hanging out with their cousins and DH doesn't mind the chaos as much as me). No one in her family ever stands up to her, and I felt on quite shaky ground limiting it to four nights.
This year the expectation (not invitation!) is there again. But I now know for a fact her kids have nits and have in fact passed it to our family at least twice. I want to tell her that they need to be nit-free before they can stay, but she seems to have a very laissez-fair attitude to it (as she does with many parenting issues IMO), and according to my FIL her kids have had nits for over a year! They don't really try and sort it, just give the younger ones hair a comb through a couple of times a week when shampooing, and get the 8 year old to do his own
.
So. AIBU? How to lay down the law when we clearly have different values (though she never respects mine)?
