Sometimes when I tell people Jacob is non-verbal, they mistakenly assume he's silent. In reality, there's nothing further from the truth. He has never been a quiet boy.
In the past he's had several sounds that he uses to "speak" with us. First, when he was about 2, he'd growl. That was fun. Next, he said "ma ma ma" for everything. At 4 years old he began with the "eh-eh-eh" sound that he'd use in a conversational tone. That one lasted a few years. The past year or so the sounds of choice were "bo", Ahh-ahh", "na-na".
