Would appreciate anyones advice on this confusing subject. My son has always been described as 'hyper' but lately he seems even worse. Has become very rude and arrogant and even though he has never been one for doing as hes told, lately hes even worse. He has always been VERY active, hardly ever sits down unless sometimes when watching tv, but even then is normally fiddling with things or kicking things round. He is not aggressive, never has been and is very intelligent, but the school always say that he needs to concentrate. Dont no if this is normal 8yr old behaviour or something else. Have a little girl whos nearly 1 and she is COMPLETELY different to him, very calm and relaxed especially compared too him at this age. Not sure if I should take him to the doctors or not.
