Right, Left, Right...

Suddenly, out of the blue, Zoey is differentiating between like and love by assigning both to different sides of her brain. That's right...

Z: Mummy, I love things on this side of my brain, pointing (right), and just like things on this side (left).

M: (speechless)

So now that Zed's thinking in terms of left brain, right brain, I'm not really sure where we go from here? Quantum Physics?

Where does a four year old find the inspiration for left brain, right brain discussions? All she watches is Wild Kratts, My Little Pony, and Sesame Street ad nauseum, so where does an idea like that take root?
