I can only reiterate what Hissy wrote earlier to you.
Re your comment:-
"Thanks for reply. It was the sil that threatened violence not mil. Mil is just a pain in the arse but she not toxic for dd- dd is 10 mo ths and mil adores her and very good with her. When dd older and capable of userstamding the crap she can talk i would then ask her to not do so or there would be no contact. At te moment that just seems a bit ott. Dh would be distraught too if his mum couldnt see her.
I wan dd to have a gran in her life as i mever did, but mil is going to need to change big time of dd is going to be around her when old enough to understand her martyr behaviour"
You are unfortunately wrong re your MIL; she is toxic and her DD your SIL is out of the same mould as her mother.
Your DD is 10 months old now, you want to entrust your precious child at all with such awful people?. You simply cannot do that to her. She is not repeat not just a PITA.
Re this part of your comment from the above:-
"When dd older and capable of understanding the crap she can talk i would then ask her to not do so or there would be no contact"
That would not happen because you cannot stand up to her now and nor can your H. Your MIL could well ignore you then if you did say anything and would likely do so, also the damage by MIL is then done. I realise that you yourself did not have a grandmother in your life and I am sincerely sorry but that is not a reason for your DD to have any contact with her grandmother now. Your DD needs decent positive role models, not a woman who does you both down at any opportunity. She herself is not decent grandmother material because she cannot treat her son or you at all with any shred of decency. Emotionally healthy people never act in the ways your MIL has done.
Some grandparents really shouldn’t be allowed access to their grandchildren.
A percentage of the general population is dysfunctional and/or abusive. That percentage, like everyone else, has children. Then those children grow and have children of their own. The not-so-loving grandparents expect to have a relationship with their grandchildren. The only problem is, they’re not good grandparents.
Many adult children of toxic parents feel torn between their parents’ (and society’s) expectation that grandparents will have access to their grandkids, and their own unfortunate first hand knowledge that their parents are emotionally/physically/sexually abusive, or just plain too difficult to have any kind of healthy relationship with.
The children’s parents may allow the grandparents to begin a relationship with their children, hoping that things will be different this time, that their parents have really changed, and that their children will be emotionally and physically safer than they themselves were.
Unfortunately, this is rarely the case, because most abusive people have mental disorders of one kind or another, and many of these disorders are lifelong and not highly treatable. (Others are lifelong and treatable; however, many people never seek the necessary help.)
The well-intentioned parent ends up feeling mortified for having done more harm than good by hoping things would somehow be different — instead of having a child who simply never knew their grandparents and who was never mistreated, they have an abused child who is now also being torn apart by the grief involved in having to sever a lifelong relationship with the unhealthy people they are very attached to.
Do not let yourself be that well intentioned parent.
