This sounds so cool! I'll have to try and find that book.
I've often felt that my 3yo is more of a visual learner, though she definitely seems to be right-handed.
She loves looking at books and "reading" them to herself and others, but doesn't usually like being read to. She'll occasionally listen to stories, but often tells me to "stop talking," so of course I do. But she's really, really into pictures, and now that she's become verbal, she has a lot to say, though it takes some effort to understand sometimes.
She loves music, singing, and dancing -- but tells me to "be quiet" whenever I sing (maybe there's not such a deep reason for that, though

... she does like it when Big Sister sings to her). She's fairly tolerant of me reading/telling stories with her big sister, most of the time -- she just doesn't like for it to be directed at her. Big Sis, however, usually prefers to save reading as our "special time" that happens after Little Sis goes to sleep, so it's not generally much of an issue.
She's very cuddly (my 3yo -- but both girls, really) -- but sometimes gets very rough, and has a strong need for regular doses of rough-housing. I'm starting to see the aggressiveness as part of her need for more intense physical sensations and emotional experiences. I've always been real big on holding and showing affection -- but my younger dd needs
more. And my older dd, though not seeming to have the same issues, greatly enjoys that we're doing more rough-housing now, too.

One thing my 3yo did a while back, was to paint some pictures that looked very much like a face filling the whole sheet of paper. She said it was a Mommy crying ... then she put her hands on the picture to rub the Mommy and make her feel better.
I'm not sure what else to read ... I'm subbing to learn more!
