DS2.5 watched that and loved it too. He wasn't into the crocodile dissection (viewed that portion as mucking up a perfectly good dinosaur show, LOL). DS seems to really get some great brain chemicals out of remembering information and naming things he knows, it seems to make him happy. Its not so much wanting to understand how things work for him, as wanting to have factual info about everything. The last little while he wants to learn what all the dinosaur names mean and then makes different words with them. The cat steals his broccoli and he says its a broccoli-lestes. He's suddenly also into what everything is made of or what produced it. I'm not sure I understand why he cares -- I don't mean that in a mean way, there is just so much else that seems like it would be more pressing for a 2 year old to ask, like "why can't I have another brownie?".
What do you think it is in your DD that motivates her?
