My dd is 10y old and throughout her school life has constantly complained about not being able to focus on what the teacher is saying or concentrate on her schoolwork when there is background chatter(of normanl kind expected in primary school). She often gets very upsret about this. Prior to that she is very sensitive to certain sounds - like brushing the patio, this would physically make her teeth hurt. We have come across a programme called the listening program, an american based programme (check spelling if looking at website) and are now undertaking the programme. It aims to stimulate auditory nerves to help re-set any sensory difficulties that have not ser during development for whatever reason. It is basically classical music which has been altered in pitch, tone etc to achieved desired results. My dd listens twice a day for 15mins and really enjoys it i think we a re beginning to notice changes in her, as she actually brushed the patio this weekend without any problem. we will continue with it for another month and see how we go.
