My SIL probably says exactly what the op does to any and all who will listen 
However what she probably doesn't mention:
My family call me to arrange to pop up and make all the effort to come to see us. (Well except for right now, we are living at my parents while waiting for a bathroom to be fitted)
Whereas she rarely speaks to me. She occasionally contacts dp, once including a long drunken Facebook rang where she essentially said I was ruining his life and making his family unwelcome. She never visits, dd doesn't really know who she is. On top of that she has made it clear she dislikes me. Why would I leave dd with her?
I arrange to see my family. I don't see why it is my jobs to arrange our family visits with do's family. That's his job, but naturally I suppose it's easier to blame me than to realise maybe do just can't be bothered to visit them or organise anything.
One of the main reasons dear SIL dislikes me is that I helped dp get over and stop his problem drinking which was destroying him and our family (alcoholic, as is most of his family)
SIL sees this as me spoiling dp's life, to the point that she drunkenly ranted at dp's 40th birthday party that 'He should just have a fucking drink, he's so fucking boring without a drink' loudly in front of him and everyone there. Tried to 'sneak' dp a drink ( poor dp was not happy) and then gave up and say on FIL's lap throwing me daggers and mumbling about what a fucking bitch I am.
Oh and has gone out of her way to not congratulate us on our healthy pregnancy this week.
Gosh reading all that I just can't see why I don't throw dd at her at every opportunity!
