I thought that being ambidextrous was a positive thing.
At least I've never heard associated with any sort of disorder.
I used to think so too! And we have a few ambidextrous folks in my family, including me
But it is associated with fine motor dysgraphia. Not everyone who is dysgraphic is ambidextrous and not everyone who is ambidextrous is dysgraphic, but the two occur together frequently. Dysgraphic kids also sometimes have issues with directions, knowing left from right etc. I think it all ties into the concept of cerebral dominance that was mentioned... but I'm not an expert or a psychologist or anything like that. I do remember very clearly though, sitting in a neuropsychologist's office when ds was 7 and hearing "he's ambidextrous" and thinking "Hey! That's cool!" until in her next breath the neurospychologist said "and that's not necessarily a good thing"....
FWIW, what "ambidextrous" meant for my ds is that he had no strong/dominant hand for any kind of fine motor task, from handwriting to tying his shoes and those types of fine motor tasks never became automatic or "easy". Not the same impact as my ambidextrous college prof who would start writing a fast pace with his left hand on the left side of the board while he was talking and then without skipping a beat switch hands mid-board to his right hand and keep on writing at that same fast pace.
