What should i do??

My husband disagrees with me on almost EVERYTHING. We have a newborn and Everytime he changes her diaper he’ll walk away from the changing table and I always tell him not to do that because she can roll over at any point now. He’ll then respond like “oh my god she’s not gonna roll over she’s been stationary this whole time it’s okay” so now Everytime he changes her I have to watch them like a hawk and run over to the changing table to make sure she doesn’t fall off. 🤦🏼‍♀️ it could be something so blatantly obvious and he would still disagree with me. No matter how much I try to convince him he always says I’m wrong on almost everything. Then he’ll get mad and storm off and go play his video games or something. How tf do I deal with this 😐
