I noticed a few weeks ago before half term my son pick pick picking a scab on his arm , when I asked him how he got it he said he caught it on a loose piece of fence wire . Explained you would think until the weeks goe by and more and more of these similar sized scabs appearing up his arm , again I questioned him and he didn`t know how they appeared . Curious and naughty I know but i searched his room one day while he was at school , found a fishing hook in his bed made sense the size of the scabs the spacing of them . I spoke to some one close to me who worked in social services for a long time with kids who said it could be self harm due to his low esteem with adhd failing him at school ect. he also has asd and complex learning difficulties and after 2 weeks of his new special ed school he said he now likes his lessons as he doesn`t feel like the class `daftie` was how he put it . Was just wondering if anyone has experienced something similar is it the adhd/asd affecting him or purely his old school geting to him that much hurting himself was taking the pain away that he was feeling from his school ?
