I got an idea to try take a picture of him with Treo, and asked the little guy to smile. It worked, he smiled and began to actively played again. I'm glad that I was able to connect with my cousin's son, although the pictures are no good since he kept moving around. It may looked trivial for some people, but I'm sure plenty of parents out there know how precious it is to see a smile of their little ones. Priceless.
