I've namechanged for this just in case as DH knows my usual nickname, this is something I have discussed with him but it's quite a sensitive subject as you can imagine.
MIL is perfectly lovely to me when we visit but a couple of things are concerning me a bit, particularly since DS was born at the beginning of this year.
She seems to take pride in having no patience and being quick to lose her temper. She brags about it. She is absolutely vile to FIL and humiliates him in front of other people. She freaks out about any mess (she physically beat FIL for spilling some tea on the carpet) and DH wasn't allowed toys out as a child, he was allowed to play with one at a time even though they bought him every single toy on the market at the time apparently. She jokes about how when DH was little, she once got so angry with him she strangled him round the neck and kept him off school until the bruising from the fingerprints had gone. DH says he was a very naughty child and was always being screamed at and he must have deserved it.
Maybe I'm being unreasonable but the above things have made me wary of her and reluctant to let her babysit DS on her own when I go back to work soon.
But the thing that has unsettled me the most is something she said at the weekend. I was telling her how DS won't nap during the day at the moment. She told me that DH wouldn't nap when he was the same age (6 months) and she used to (she did an 'angry face' at this point) wrap him up so tightly that he couldn't move then shake him and shake him until he went (she did a 'eyes rolling, tongue out and floppy head' impression) then put him in the cot.
This upset me so much, I couldn't sleep last night for thinking about poor DH as a 6 month baby with her as a mother.
This has made it clear in my mind that I do not want her looking after DS.
I'm not sure how to navigate this diplomatically - she has already arranged to retire early at the end of this year so she can be available to look after DS when I go back to work. She is always perfectly lovely to me (apart from a comment about breastfeeding being disgusting and a couple of mucky looks when I try to start a conversation with FIL).
I know there are people on here with far worse MIL issues but I just don't want her spending time with DS on her own.
Does anyone have any ideas what I can do? I think DH would support me, he knows I'm uncomfortable with her temper and abusive relationship with FIL (I also wonder how I can protect DS from the way she is with FIL - I don't want him to think it's OK to treat people like that but at the same time I don't want him to think it's OK to just take the abuse like FIL does. I also want to be careful how I deal with this subject when DS is older as I'm sure he'll love his grandparents to bits).
This has turned into a bit of a long ramble. I guess I just wanted to talk really and seehow others might feel in the same situation?
