What we were told by the OT is that either left handed or right handed is fine, but ambidextrous is bad. An OT sees strong handedess of one sort or the other as important for neuro development / maturity. They also need a strong understanding of which is their left/right and should be dominant on the same side for hand, foot and eye.
I'd be interested to know why it would be important to be dominant on the same side for all things. I'm left-dominant eye and ear, right-dominant hand and foot, and except for using a bow and arrow (choose between weaker draw or aim with weak eye), it doesn't seem to be causing me any problems.
