Why your child covers their ears — understanding sensory processing

Your child isn't being dramatic when they cover their ears at a hand dryer or refuse to wear socks with seams. Their nervous system is processing sensory input differently — and for them, that experience is genuinely intense. This is called sensory processing difference, and understanding it can transform how you interpret your child's behavior.

Every brain takes in sensory information — sight, sound, touch, taste, smell, movement (vestibular), and body position (proprioception). Most brains filter and organize this information automatically. But some children's brains turn the volume up on certain inputs (making them hypersensitive — they feel too much) or turn it down (making them hyposensitive — they seek more input to register it).

This explains so many puzzling behaviors. The child who crashes into furniture may be seeking proprioceptive input their brain isn't registering well. The child who gags at mashed potatoes may have oral hypersensitivity. The child who spins endlessly may be seeking vestibular input. The child who has meltdowns in crowded places may be overwhelmed by simultaneous visual, auditory, and tactile input.

An occupational therapist can create a sensory diet — a personalized schedule of activities designed to keep your child's nervous system regulated throughout the day. This might include things like jumping on a mini-trampoline before school, using noise-canceling headphones in loud environments, or offering crunchy snacks for oral input. Small accommodations, enormous impact.
