It's been less than 12 hours since we gave it to him, and maybe I am speaking a little too soon but, YAY. We've had some of the quietest car time in 4 years.
Except for when he speaks. Because he does not yet understand that because there is noise in his ears, he is shouting when he talks. But I'll take it.
Ahhhhh, the sound of silence (in the car....)
