Mother in law drama

Am I crazy for being upset?

My husband has his daughters every other weekend. And his mother constantly tries to say they need to come to her house. I tell my husband you have four days with them you need to spend the time with them. But my mother in law always throws a tantrum over it. And will not talk to me when it happens. I’ve even had to cancel my plans before because my husband let her have them.

Then on Christmas ornaments she gives me one of me and my boys but gives him one with his daughter and her and him. Like why couldn’t she just do one with all of us on it?

Then now I’ve been made to where I can’t message her because I said I wanted a family night without her and she said she won’t even do Christmas with us.

Am I crazy how do I handle this?
