Dd11 was somewhat ambi when younger, but is a right handed person now. She and I can both use our left hands and do for things like eating, but we both write right handed. We had an OT who evaluated dd at the suggestion of the GDC tell us that her lack of preference for one hand over the other in stringing beads, for instance, indicated a pathology/dyspraxia at age 7.5. I'm not tremendously convinced of that, though. Dd is probably HG, but not PG.
