Dh has a close family to say the least, they would arguably rival the Windsors.
Anyway, on Mother's Day we suggested taking his mother out for the day, which she managed to turn into the usual palava inviting one of DH's brothers, his wife and their 2 children, whose best behaviour is not the err...best. Also came was FIL's brother and wife and one of their son's and their children who are 12,9 and 7 and frankly are like hooligans.
ANYWAY, where we went was a sort of rundown castle, lots of child friendly activites etc, one of which was crossing a fairly shallow river on stepping stones. So all the children were crossing this, I was sat on the bank with my youngest who is still a baby, and DH, BIL and their cousin were helping the kids. DD got a bit panicky when crossing the stones and was dithering a bit. After around 10secs, DH cousin's eldest came up behind her and shoved her so hard she literally was thrown in the air and landed around a metre from where she was standing having banged her head pretty bloody hard on the stepping stone. Then the cousin's three kids came up and started kicking her, she was now in the river, and throwing water all over and calling her names. Dh's cousin and his wife at no point intervened, and neither did MIL or Dh's uncle and aunt. DH and myself left immediately and took her to hospital to get her checked over, no damage but she was hysterical.
Anyway, the orginal plan following the day out was to return to our house for food which DH and I were cooking. We obviously assumed given the events this would not be occuring but at 5, MIL, DH's uncle and aunt, cousin, wife and children appeared expecting to be fed. Cue massive argument as we were told that "kids will be kids"
AIBU to not want my DC around these people, this however will prove hard as such a close family
