He is so interested in it that we put this Beleduc 5 Layer Puzzle on his Christmas List and his Tita Elizabeth (the physical therapist, go figure! :)) got it for him!
He knows all about bones, cartilage and joints from The Skeleton Inside You, and has a pretty good grip on the concepts of digestion thanks to The Magic School Busy Goes Into The Human Body. I mean, the kid knows what villi are. Seriously? A three year old? I'm pretty sure I learned that word in Medical Terminology my senior year in COLLEGE! Ok, maybe it was Anat & Phys my sophomore year, but I was no A&P whiz and things seemed to fly out on my brain as fast as they went in.
I had the boys at the pediatrician today to check on Ian's ears (he's been battling an EI for who knows how long) and he had his Magic School Bus book with him. He started talking to the nurse about, you're never believe this... BLOOD VESSELS. She was floored, as was I, I haven't heard him talk about them before!
So now here is my wondering... do I encourage this and keep searching for new (age appropriate) books to expand his knowledge? I don't want him to be some super weird Dugie Howser when he's 10, but it's probably just a passing phase, don't you think? He's doing very well with knowing all his letters and we're now working on writing letters. He's great at counting and just starting to graps the concept of adding really small numbers together when we're counting objects. So I think if I just make sure he's not falling behind on normal stuff like that, it should be ok. Or maybe I should really push it and then I can retire early and he can support his parents! HAHA, I can dream, ;-)
