Can I ask anyone whose DC have PDA how their DC cope in school and through the diagnosis process? I know children with ASD in general can hide symptoms in some settings but is this common with PDA too? Advice I have had so far is that when they are very little and don't go to school much they can more easily hide it at school than when you ramp up the pressure. Will DS be able to hide his symptoms during the 6 week assessment center? DS is only three but is making me feel like I am imagining things after three amazing days in preschool acting like head boy.
