my DD8, has always been "quieter" and I guess you might even say withdrawn. Even in a group of friends...she just does better one on one or two...she also prefers jeans and tshirts...like she would just prefer to not be noticed. She doesn't like to "perform" and now that she's older, it's obvious to me that it's about relationships and who she feels more comfortable with.
He IS still a preschooler, after all...remember, he needs to know that you love him for him, not maybe what he can do (not that I am saying YOU do that, just something I read recently about self esteem). Sometimes we unconciously put more pressure than we realize on them, you know?
My DD was and STILL IS like that, not very forthcoming unless something REALLY exciting happened...and it better be REALLY exciting, kwim?
On the other hand, my DD4.5 can rattle off in minute detail every moment of the 6 hours I wasn't with her *sigh*
