Bf doesn’t want me taking pics of him and our baby

My bf and I are expecting a baby and we were talking about the baby and stuff and he goes “if you try to take pics of me holding the baby I’m gonna be p*ssed” he hates pictures in general, but I think it would be nice to have pictures of him and the baby to look back on. Any advice?

Update: I honestly don’t think he’s cheating or that there is someone else. He’s really sweet and I figured if there is someone else he would be acting differently towards me. He has hated pictures ever since he was a kid. I think it’s more of an insecurity thing than anything else. He always says he hates the way he looks in pictures and he doesn’t like his teeth so he doesn’t like smiling in them which he honestly has a great smile I just wish he would see that. I really hope he gets over this when the baby comes. He did agree to do maternity pics with me so I think we’re making some progress. He was like this both years for our prom he just gets frustrated during pictures. He also said he didn’t think he’d be able to cut the umbilical cord because it would gross him out but I’m still working on that one. I understand that it is kind of out of a comfort zone but that’s like the tradition and I want him to feel involved with everything and I think it would be kind of cool, but we’ll see how that goes. I still have a ways to go so maybe his feelings will change when The time gets closer.
