My DS is 7 and recently diagnosed with ADD being predominantly inattentive. OT and speech therapist spotted it before the Peadiatrician. There are heaps of things they can do to help out in class, and if they don't work perhaps medication could be another option. You could ask the teacher (or school learning advisor if they have one) to write a letter including the report form the OT's in the classroom and take that with youth the GP or try to get a referral to a Peadiatrician to see what they recommend. Good luck - it's a long road with little people with extra needs but so worth it when you see the results coming through.
