Delivery

Ok I know it's kind of early to talk about this but I'm five months pregnant now. My boyfriend I were talking about who would be in the delivery room. I said I wanted him and my mom...he said she shouldn't be there because it's an intimate moment between him and I. I get it but this is my mom's first grandchild and she's been there for me since day one. Making sure I'm eating right and even going to ultrasound appointments with me when my boyfriend couldn't. She's super excited and I feel like I would want both of them to share the moment with me. What are your thoughts?
