More questions no answers

Caleb has a sensory disorder and  ADHD, well we haven't medicated him but his teacher thinks its time. He is really struggling in class and his class is specialized with only ten students. So today, we went to the drs to talk to her and I am blessed to have a great doctor but more questions are now being asked and assessed. The Dr. is not putting him on medication because she does not know what affects the medication can have on the issues he is having. Also, she wants him to see an Autism specialized Psychiatrist. She believes he needs to be reevaluated even though another psychologist stated he did not have autism or aspergers, because she is not sure if this is correct. So again, here we are I feel like back at square one but whatever is ahead of us its ok because i know we will make it through and we already have been very aware that Caleb has special needs and have been working on it. Just want some definitive answers so we can help Caleb learn and live.
