Early childhood
Early childhood (3–6 years) is a period where learning environments, social-emotional skills, and independence rapidly expand. This page provides an orientation to the stage and links into the topics library as it grows.
What matters most
At ages 3–6, the goal is skill building: repeated practice in real-life contexts (not “perfect performance”).
