Colin's Tricks: Gestures and Signs

My grandson Colin only speaks a few words that I can clearly identify--his words for Daddy, Mommy, and Grandma, sounding like /da da/, /ma ma/ and possibly /na na/. Sometimes he seems to call me, his Grampa, something like /ah jah/. Amazingly, he has a larger repertoire of gestures, including a couple that are very close to American Sign Language (his own dialect of ASL!). The video above shows many of these gestures and signs.
