That's really interesting nickle730 and Zazou, I just had a quick look at the wisc-iv test.
The Paed did not elaborate on what sort of testing she was thinking about. This appointment was the first time she mentioned further testing as we initially went for his day time incontinence.
She had mentioned it based on how he is at the appointments and me bringing up the what went on at the meeting with his Teacher.

I read in another thread about the sensory cushion, at one stage the teacher mentioned DS2 had asked (he had seen another little boy with them) if he could wear headphones to block out noise. She gave them to DS2 and said that he actually sat and did his work withing minutes.

He is the sweetest funniest little boy, so in some ways this has come out of the blue to myself and DH.

All very helpful..Thankyou.
