This is totally normal in my experience. I have talked to a lot of other women about this and I think men are generally timid around kids that are under two because they feel inadequate because the whole process comes more naturally to us as women and they don't want to mess something up.
I got my hubby more involved by giving him tasks like bathing the kids, entertaining them while I showered, that sort of thing. Then I would be sure to compliment him on how awesome he was with the kids. Over time his confidence grew and he was more involved.
I think men just assume that we got it all handled so they don't help out. I don't think it's intentional, but I do think they are intimidated by babies, even if they don't admit it. I would just recommend giving him some jobs, without letting him know what you are doing, and then praising him for it that way you don't end up feeling resentful.
Good luck!
