For years, attention-deficit/hyperactivity disorder (ADHD) has been defined by three core symptoms: inattention, hyperactivity, and impulsivity. If your child struggles to focus, sits still with difficulty, or acts before thinking, ADHD may come to mind quickly. But what if those aren’t the whole story?

Some children experience the world at a higher volume. Sounds feel louder, emotions feel stronger, changes feel bigger, and social experiences leave deeper imprints. These children are often described as “too sensitive,” “overreactive,” or “easily overwhelmed,” yet these labels miss what is really happening. Highly sensitive children are not broken, weak, or immature. They are wired to process information deeply and respond intensely.
