Help 😭😢

Amy

So tonight I was putting cream on my three month old for his eczema and he suddenly starts to Scream and cry.. So i try to calm him down then his father demands i give him. To him and makes it seem like I'm a horrible mother and when I try to say anything to him he starts to tell me to shut the fuck up . starts to hit an toss things next to him. Towards me and I feel like he's going to hurt or kill me.. I don't know what to do. I need to protect my SON !!!
