My son is HOH wears aids. He begged to go to karate so I let him. He has a one on one who gives him direct instruction and theres is a group leader. He was hurt last week. I asked him what happened he said that te boy was blocking his view. He's not allowed to wear his aids in class or fights and I worry he will be hurt. I spoke to the teacher and he asked me if he was a hearing child would I be so worried? I had no answer anyone care to comment...
