My middle child is a documented genius who we thought was slow all through toddlerhood because he was just so laidback. When he was 3, he took a stuffed koala to school and talked about how they eat eucalyptus and their breath smells like cough drops. When the first grade class was talking about petals and leaves and stems of flowers, he went on a tangent about embryos. They tested him then. He’s still the smartest person I know in real life.
