Not what he expected

I'm currently 21 weeks pregnant with my husband and I's first child. We found out last week that we are having a girl! I couldn't be more excited! My husband is very happy to have a baby coming but still isn't too sure about having a girl. He was really looking forward to having a boy, so we have been disagreeing on how to set up the nursery and what we should name our baby, etc. He feels like he just won't know how to bond with a girl like he knew he could with a boy.

I want to help him feel more comfortable with being a new dad to a baby girl but I'm not sure how to do that. His dad walked out on him when he was young, and his mom has been married 5 times so far in his life so he has never really had a good male role model in his life. I'm very thankful for my own dad to be around, who has 2 little girls (including me) and was a single dad, so I suggested to him to reach out to him and talk to him about his concerns and stuff, but my husband does not know how to feel comfortable to ask another person for help. My dad would be more than happy to do anything for him! My husband and my Dad get along very well! I always joke with my husband that hes the new favorite child now that he is in the picture lol. They have so much in common and really enjoy being with each other when they can.

I'm just not sure what I can do, as his wife and best friend.

Maybe I just needed to vent it out.
