I don't think you're strange. I feel pretty much exactly the same way. I feel very excited about getting to know DS as he grows and develops. I wonder what he will be like at 1yr, 5yrs, 7yrs, 13yrs, 18 yrs old. I don't think I have many expectations of him at all in the sense you are talking about. I do kind of expect that he will be a 'good' person according to my definition of good (care about himself and others, not intentionally hurt people, be generous etc etc) but that's because I plan to try and instill those qualities and values in him. My expectations of him I guess are all intangible things - inner qualities that have nothing to do with personality or things like introversion/extroversion.

I actually get a bit annoyed when I hear others express their expectations of him - that he'll be good at sport or intelligent or become a doctor and I have always responded that as long as he is following his heart and he is happy without harming others I don't care what he does.

You're not strange (or at least, if you are, there's two of us ).

ETA - I don't think I "expect" him to be happy - I do hope that he finds in life and in himself reasons to be happy though.
