An interesting aside- my early walker/climber is very visual and though she was diagnosed with mild myopia (near-sightedness) at age six, she is eight now and her eyes have gotten much, much worse. I was so upset when we came home from her eye exam last week, I said to my husband, "What does it mean to be visually oriented and not be able to see?" He was quick to remind me that he is almost legally blind in one eye and is also a visual person... the apple doesn't fall far from the tree.
