I reaad this thread with interest and then a little bit of concern. Coppertop, if you're there- please reassure me that this proabvbly doens't apply to my dd1 ( also aged8).
She is quite aggressive too - for no apparant reason will lash out at her siblings. Yesterday she put a note through my ds bedroom door saying "you are a poo"(about the biggest insult that can be delivered in our house) for no reason and then laughed when he cried.
She is very affectionate towards her siblings when babies but this changes as they get older ( about one and a half ish).
She also always has to be told to do everything - brush her teeth and hair otherwise she'd forget. She's also excessibvely shy and nervous - school always comments. Doesn't always know appropraite behaviour - when soemone says hello in playground she'll often turn away. I've explained to her that that is considered rude and that even if she is feeling shy or tired etc she must still at least smile, but she doesn't.
Aside from this she's bright. Used to be top in her class in receoption but as years gone by work has decreased in standard. Her writing has always been but noticeably more so now she's older very messy and she doesn't take care wit her work - will often hand in something dog eared. Taking ages to complete work for Brownie badge as she seems incapable of understanding or planning her artwork in that it must be of a certain standard and not just any old thing.
She used to be very popular in reception - a happy little girl with many friends. Became more quiet and shy and introverted as years went on and now only has a few friends.
On up side ( and against diagnosis of anything "wrong" so to speak) is fact that she is still fairly bright ( half way up class), plays nicely with friends she has, is responsive and emotional and enjoys touch and cuddles and is not distant or unreachable or anthyibng like that.
Probably just prickly and difficult personality right?
BTW sorry for hijack.
