Hi sammum,

I feel that being shy and being self confident are two different things.  One can be very self confident and have high self esteem, but prefer not to be in crowds or be the center of attention.  There's nothing wrong with that, it's just the way they are and their preference.  

Don't worry!  You said he is very loving and I can tell that you are a very thoughtful, concerned parent, so I don't think you have anything to worry about.

Continue to show him love, attention and praise his work and good deeds.  Remind him how handsome and loving he his and reassure him that you love him, no matter what-this will keep his self esteem high, don't force him to join in a crowd that he had rather not be a part of or place him "on the spot" that could lead to embarrassment and crush his self esteem.  He'll be fine.

As he matures he may become more open to people, but he may not ever really want to have attention focused directly on him.  He can still be outgoing and achieve wonderful things.  Shyness is an endearing quality that can be a blessing, shy people are more likely not to get into as much trouble as those that put themselves in other situations.  From my own experience, I stayed out of trouble because I didn't want the attention that it would bring.  Shy people tend to look at friendships for quality more so than quantity and they are much more attentive to others needs instead of their own, which leads to better overall relationships and a more committed, focused lifestyle.  So look at it as a blessing.
