I felt exactly the same way. I wonder if it might have been sort of a psychologial defense mechanism or something to deal with the image of all the NICU stuff. Or, it may be just the result of such unnatural circumstances: c-section, mom on mag, no immediate bonding, etc. I can remember watching my son grow the first year in amazement that he even came out of me. I wasn't even in maternity clothes yet when I had him.
My advice to you would be to try to get the nurses to let you be more involved in his care. He seems like he's doing well enough that they would. Comfort him, change his diaper, feed him (if he's taking bottles yet), take his temperature, and the biggest thing is to hold him, skin to skin if possible. Talk to him and let him hear your voice. He knows it. And even now, he's got a little personality... once you see it, you'll be hooked.
On a side, maybe related, note, when my son came home, swaddling would not comfort him. In fact, he would get more mad. We were like HUH? But the baby book says...? He was used to the isolette, and being flat, generally without any stimulation. He was never big enough to be scrunched up in the womb, and the doctors say that explained it. But I had to comfort my baby and turn it around (crying = low oxygen), so I studied baby wearing and through that things changed. In fact, my carrier became the only thing that got us through colicky evenings. I still use carriers a lot and he's now 2. He's not overly attached to me (I worried about that), in fact he's NEVER ONCE cried being separated from me. He's such a happy, fiercely independent little guy. I wonder if the NICU had an effect on that?
