I just recently discovered "StumbleUpon" (thanks Lindsey!) and I came across a video tonight that is too amazing for words... it left me in tears. Maybe it's because I'm a mom, but watch for yourself. This is a video showing the activation of a cochlear implant on an 8 month old baby, who was born deaf. How sweet to see his reaction to him hearing his mother's voice for the first time.
If that doesn't make you smile, I don't know what will.
