It sounds like there's a lot of background.
I had dinner with 5 other women on Saturday and were discussing in-laws. We came to agreement that at some point, immediate family of spouse and kids has to come before parents/in-laws and boundaries need to be drawn. My parents have always been very sensitive to "intruding" on our family. DH's father and step-mother have always been sensitive. DH's mother and sister have no boundaries. There were a couple of borderline incidents that DH and I discussed but they went by. All it took was one really crossing the border incident and DH spoke to both of them and laid out the guidelines. I'm sure I was not popular as the witch who made him stand up to them, but it had to be done.
It sounds like you may need to press DH to finally stand up to them. Even if it means that you declare that you are no longer comfortable with your children in their care and they cannot visit unless you are either supervising or give full approval. And make it DH's responsibility to convey that to your inlaws.
