Solomon?

This post is primarily a question posed to all of you biblical scholars out there. I am doing some research for a series of wednesday night youth talks entitled "the beloved of God." While doing some research I came across 2 Samuel and the narrative of David, Bathsheba and the birth of Solomon. I have read that passage before but never noticed that God declared through the prophet Nathan that Solomon's name was to be Jedidiah "beloved of God." Please tell me how I got through a Christian College and even a seminary without noticing this?! Anyway, further research has shown that the name Jedidiah is not mentioned anywhere else in scripture. In fact, every time that God speaks or refers to Solomon, God uses the name Solomon and not Jedidiah. I have a couple of ideas of what could possibly be behind this. I would love some feedback though from you OT scholars out there.

Shalom.
