You don’t need to feed the beast of hate. But what you can do is far more damaging, you can cut her I Married A Superhero Shirt out of your life. If you can coordinate this with your other brothers even better. But you need to think how this will impact your children.
You may not think it will, but it will. My grandmother always favored a few of my cousins over my siblings and myself. Suffice it to say it was very obvious and we had no relationship with her because of it. In the end nobody, including my mother (her daughter) went to her funeral except the grandchildren she thought were superior to the others, and who she left the bulk of her estate to. The best thing I can recommend is cutting her out of your life until she grows up, but I don’t think that is ever going to happen at this point.
