Kids’ sensory processing issues change gradually, starts at the age when they are toddlers from when they are high-schoolers. Babies and preschoolers have very fussy sensory processing issues and often they are over-sensitive. When they are grade-schoolers they feel uncomfortable in different social situations and transition phases, while this feeling turn into impulsiveness when they are middle-schoolers. Finally they start to come to a steady mood when they are teenagers, but still feel uncomfortable to find out personal space.
