My dd5 seems completely ambidextrous. Since being taught how to print letters in pre-k, she has now chosen to write with her right hand (perhaps the teachers suggested it?). But when she was first starting out, she would switch hands back and forth frequently - making the big vertical line for an "E" with her left hand and the horizontal lines with her right. I'd never seen anything like it!

I think I read somewhere that being ambidextrous can be a sign of giftedness. Or maybe I made that up grin
