My Dn is 7. He is a very precocious child (in the positivie sense)and as a result can be very demanding. about 18 months ago there was a discussion and consultation as to whether he ahd ADHD or not, no firm diagnosis was made Ritalin was tried but DB and SIL stopped it as he ahd side effects. He has done well over lat few moths with strict behaviour regime but now is constantly tapping his hands, scratching himself and pulling his hair and obviously distressed. MY DB and SIL need help any suggestions?
