I am the mother of a 16 year old boy that has been diagnosed with Severe ADHD, Asperger’s, Pervasive Development Disorder and Sensory Processing Disorder. I can attest that he has done much better in calm, quiet classrooms especially during his Elementary years. I believe that I too have some Sensory issues myself. Our family has been quite open about these issues regarding my son which I believe has really helped him at school. Regarding telling your colleauges, if you are concerned about their reaction then don’t tell them. It is your business and it doesn’t seem to affect your ability to help your students or to perform your job. Instead it is a bonus and you completely understand where these children are coming from and why they react the way they do. Keep plugging along – you will find more strategies as you continue on your path!!!
