Understanding Sensory Underresponsiveness
Research shows that sensory underresponders have a nervous system that reacts slower or less intensely to sensory input. This can manifest in children not noticing their name being called or failing to register background noises. They might also exhibit delayed responses to pain, which can be concerning for parents and caregivers.

Many families discover that sensory underresponders fall into two distinct categories: those who appear tired and sluggish, and those who are constantly seeking sensory input. The former group may seem disengaged, often sitting quietly in the corner and slow to participate in activities. In contrast, the latter group is always on the move, craving more sensory experiences throughout the day to stay engaged and alert.
