I need to find someone who has experience of dealing with a child who has the following symptoms.....at first we just thought our little boy was naughty, then we thought he was hyperactive.....now two years down the line we are slowly coming to the end of our tether. ADHD has been assessed but paeds cant fit him neatly into a box. He has difficulty sitting still, difficulty sitting at all, he tends to sit on his heels. He licks his hands constantly, licks other children in his class and licks walls etc. he is a loving little boy and we adore him but he is struggling at school and i need help. The last opinion mentioned "sensory issues" but ive no idea what that means......HELP!!!!!!
