I join you in your observation that it doesn't seem doctors/professionals like to diagnose sensory issues. My daughter was in a special ed preschool with a highly experienced teacher for children with disabilities and where she was evaluated by a PT twice and had twice a week speech therapy. Twice a year for two years they kept telling me about her "issues" but no one every suggested sensory issues until the final team meeting when she was moving up the kindergarten. During that time we were struggling with potty training so we saw a urologist, who after finding nothing physically wrong, referred us to a child behavioral psychologist. We saw him for eight months--also no mention of potential sensory issues. I asked him at two appointments if he thought she should be evaluated for autism because my day care suggested it, believing she had some mild symptoms. He replied, "no, she clearly isn't autistic. If she was evaluated they would likely say she had PDD of uncertain origin, and you would just continue doing what I'm already advising." So we kept on following his "prescription" for potty training, with no change for 8 months. Finally, we decided to see a psychotherapist thinking maybe she had some unresolved trauma from neglect by her birth mother. She saw her twice and told us she couldn't put her finger on anything wrong and didn't think it would benefit her to come back. My husband and I have finally given up on being angry at all these professionals who were either ignorant of SPD or couldn't be bothered to advise us to get her evaluated. Now we're just thankful we know what's wrong and pursue treatment. I know it seems scarey that he will be labeled, but it will open up opportunities for him to get the services he needs, especially during his school years.
