Update on Jack: Jack is now in 4th grade and doing well. He is an A-B student and his reading is getting better with each passing month. He is currently envolved in Hockey and plays goalie for a local hockey club. He is doing well and loves it. He does well hearing with his helmet on and we have not hand any problems with sweat, like I thought we might. His goalie helmet fits well around is implants without any customization. So.... not the case with his regular player helmet. We had to cut out an area to fit his implant which always makes me worry about an impact because he is not protected where it has been cut out. One reason I'm happy he is sticking with being a Goalie....better pads all around, and his helmet fits well and he is able to hear well with it on.
