My 11 year old son was premature (1 month) ruptured lung, he has problems when people talk loud, or when someone is speaking to him loudly, he blocks them out, which is not good when it is the teacher. If you whisper, he gets upset. He seems to lose his temper with his younger sister and parents more so than with his friends(he appears to hold it in). He has trouble focusing on things that do not interest him. He has trouble doing his homework, because he is easily distracted, so it will take him a lot longer to do it. We went out on the river with about 25 children his age, using "duckies" to paddle down, and he was the very last one by a long distance, he had trouble coordinating how to use the paddles, and he is physically not very strong. any suggestions.
