All that reading finally pays off....

Here you see Amara's anatomically correct drawings of her veins and arteries (in red and blue), and on her knee please notice the knee cap (black). If I'd taken a picture of the rest of her body, you'd see her lungs and a lovely red heart drawn on her chest. I've forgotten now what other body parts were included, but I think you get the idea.
We did recently check out an anatomy book from the library, as well as a magic school bus book about the body. She's pretty into how all that works right now. We kind of skipped the reproduction section for now, then had to return the book anyway. Is 4 too young to go there? Sigh.
