Amazingly talented 2 year old

I may be biased because I gave birth to him, but Hayden is the smartest 2 year old. He learned to play my iPod today. He can play the music and listen to the ear buds in his non-implanted ear. I'm really curious to learn when he's older if he can hear anything in the implanted ear. He's supposed to be deaf, but could have some residual hearing. He will truly be the smartest kid when he asks for his own!
