Brain size

Eli is very very obsessed with dinosaurs these days. All he wants to do is play with his dinosaur figures or read books about dinosaurs. We get lots of library books about dinosaurs, and many of them discuss their brain sizes. An apatosaurus, for example, has a brain the size of a walnut. Suprising, given it is one of the largest dinosaurs that ever lived. Anyway, I am not sure that Eli understands exactly what a brain does or is. But he likes to talk about brains and brain sizes. When we wear helmets for riding bikes, he says he is protecting his brain. Today, on our way to Toddler Time, Eli told me to run. Mama: Oh, Mama can't run today. Eli: Why? Mama, pausing because she is so tired. Eli: Cuz why your brain is too small?
