Today was BILs wedding. I'm currently sitting in the hotel room with my toddler, DD and DSD trying desperately to keep DSD awake as she had a big bump to the head tonight thanks to MIL. MIL was standing in front of a concrete post and kept encouraging DSD to run into her arms, then one of the times she just moved out of the way at the last second and DSD ran into the post at full speed, banging her head, then her mouth on a nearby table on the way down. She's been too upset to let me look at her mouth properly but I think she may have dislodged one of her adult teeth
After it happened, MIL told her 'this is what happens when you get over-excited' 
At Christmas there was a family gathering and FIL was playing with DD, throwing her up a little and catching her. Then he missed, she banged her eye on a radiator and ended up with a black eye. MIL has also dropped my toddler but luckily I was able to grab her before she hit the floor.
I might be able to excuse these as accidents were it not for the fact that a) they never apologise or accept blame b) they turn it around to be the DCs fault but most importantly c) they have had copious amounts of alcohol before these 'accidents' happen.
Poor DSD has been distraught about her tooth potentially coming out as it's a front adult one and DH joined in with MILs blaming of her and said she should know not to play with people who have been drinking
I said it was MILs responsibility to not play such games if shes been drinking and in no way DSDs fault. No doubt they've all forgotten about it downstairs while DSD is still sobbing into my tummy as we watch Frozen.
PIL are supposed to be having the DCs in a few months as I'm pregnant but knowing they'll probably have a drink to celebrate the birth (and drink most days anyway) I'm feeling extremely reluctant to leave them with them. AIBU to be furious with them?
