Hi, My son was diagnosed with ADHD when he was 7 1/2, three years ago.. He is non aggressive, just finds sitting still hard and concentrating at school even harder....things that I did that worked for me:-
Hubby and I went on a parenting course, to help us deal with his behaviour and be more positive with him.
Bought the book "Understanding ADHD" by Christopher Green.
Joined ADDIS
Removed all artificial colourings and preservatives from his diet (sugar was not really the problem). Immediate transformation.
Did some OT to help his coordination (not sure how much it helped)
Spoke to his teachers about how they could help him. Had a homework buddy/ someone to explain things to him again. Learnt to put his hand up when he missed something. Asked them to make instructions shorter, use simpler words. We also gave him a wriggle cushion to sit on at school and a ball to squeeze during lessons to help him concentrate.
Got his eyesight tested and his tracking.
Ed Psych helped by giving us lots of recommendations, but made sure we only tried a few new things every year, as we didn't want him to feel like an experiment.
Resisted putting him on Ritalin for over two years, but finally agreed and he seems to focus better. He knows when he needs to take it.
Hope some of this helps. I felt angry/frustrated a lot of the time, as there is not really one thing that works for everyone. Other people can be really unhelpful. As he gets older it will get easier. My son is now able to tell us when he can't do his homework straight away. He tells us when he needs to walk araound, when he needs to go and kick a football around for half an hour as his mind feels too busy. The parenting course made us see things from his point of view and we shout less at him in frustration.....
