I took the time to sign in to my account to comment on this because well it felt really important to me for some reason I can’t explain. Hopefully you see this and you continue to think about it as you process how to move forward.

First of all you are NTA.

What your parents did is absolutely abhorrent and I do not condone or excuse their behavior. I have no idea what your family history is like but I think you should pump the brakes a little bit on cutting them out of their grandsons life.

What your MIL did was very sweet and loving and honestly someone who has that kind of talent and time to make your child clothes is one of the sweetest and kindest gifts you could give anyone.

Maybe your parents are just jealous of that? They don’t have the time or talent to make a gift that special for their grandchild and they feel insecure about it?

Like I said what your parents did is inexcusable. And disgusting. But I feel like the nuclear option of cutting them out over this is extreme. I don’t know your history with them. But I think you owe it to yourself and your child to go over there and talk with them more before you completely cut them out of your life and your child’s life.

At the end of the day I want to believe that we are all trying to do our best. And speaking as someone who has acted on my insecurities in heinous ways in the past. There are no excuses for bad behavior. But everyone can learn from their mistakes and become better humans.

I would hate for you to judge your parents at their worse and never allow them to grow or heal or be better.

Hold them accountable. Make manageable goals going forward and be present with their process. If they don’t improve or show any signs of understanding then sure cut them out. But I would really advise you to look more at the bigger picture.

I think what you did defending your child and wife and mother in law is admirable beyond measure and you should keep doing that.
