Welcome to the Forum and thank you for sharing your dream, which I do not perceive as bizarre
I like to share what arose while I entered your dream, and I trust you know that in the end you are
your own dream expert.
You have given birth to part of yourself and you are giving it every effort to take care of it.

http://dreamhawk.com/pregnancy-childbirth/the-baby-in-your-dream/The father in the dream is present, although his presence is vague. I see it that your dream expresses
with a different symbol that this male principle in your life still needs some healing, and then its (his) presence will become less vague.

http://dreamhawk.com/dream-encyclopedia/archetype-of-the-animus-jungs-view-of-the-male-in-the-female/It is not uncommon that when we give birth to a new part in us, that we are faced with some unhealed aspects of ourself. Although these unhealed aspects of us can have their roots in our babyhood, we can meet them as an adult again so it can be healed when we are ready for it.
To me the dream shows that you ARE ready for it.
See
http://dreamhawk.com/dream-dictionary/half/I feel that the response from both the doctor and your baby son in your dream, are those parts in you which have grown to a point at which you do not make a big deal out of this aspect not being whole (yet), and it also shows that you can allow the healing forces inside you to work towards becoming whole again.
It is like the baby communicating to you without words:"I am aware that I am not whole yet and I can smile at it" and if you can look at it that way too, the "healing forces" will take care of it.
A loving dream!
