Nervous about circumcision

Hey everyone, I'm 30 and 18 weeks pregnant with my 4th child, my first boy. I am so freaking nervous about circumcision. Any moms of boys with any advice is well appreciated. I watched a video of an infant circumcision the other night and I'm absolutely traumatised. My husband wants him circumcised so this is going to happen so please don't try and say negative things , I need support here. I don't want my baby to feel pain😥
