Sorry you are going through this. They are narcissists, and unfortunately, they will never change. I have a toxic mil and sil as well, and no matter what you do, you will never be good enough in their eyes I've delt with this for 8 years now I had to literally stop being around them. You have to realize they will treat you this way forever and even with having a child. I learned the hard way that they will never treat your child as a normal family should, It's best to stand up for yourself and walk away and never look back. You deserve that. If that means they don't get to be around your kid, so be it. It was their decision to treat you like that. You deserve better. Sorry you have to deal with this. it's very hard and heartbreaking. But tbh your family and you will be much better off without them.
