Children who are tactile defensive have an increased sensitivity to touch that is caused by the way in which the brain processes tactile input. Children can be over responsive or under responsive to tactile input. Children who are over responsive to tactile input can feel overwhelmed or avoid every day touch. A child who is over responsive to tactile input may avoid daily activities or items that bother them, such as hugs, walking barefoot, tags on clothing, touching dirt/grass/paint, bathing or washing hands, etc. Children who are under responsive to tactile input generally seek additional sensory input throughout their day to provide a neutral state of comfort. These children seek constant squeezes, messy play, touch/pressure, etc.
