In laws not listening

We visited my in laws yesterday. I kept having to tell them to hold my baby's head. Hes 8 weeks old today. My mil was apparently upset about that. She told me that he can hold his head up by himself. Shes obviously wrong cause his head fell when she was holding him. Which i told her. I just took him back and held him myself. I dont have time to play politics with my child's safety. Mil or not when it comes to my son i have zero tolerance.

I know shes upset but thats her problem. My husband asked me if I said anything to her and I told him that I had to tell her AND his aunts to hold my son's head. They are upset. As if thats gonna stop me from being my son's mother.
