Understanding and Managing Biting Behaviors

How can parents help their child overcome biting behavior?

By Dr. Divina Lopez, MD

Children with autism often bite, and this behavior can leave parents feeling overwhelmed, concerned, or even helpless. Seeing your child bite others or themselves can be distressing, and the reactions from caregivers, teachers, or peers can add to the stress.

However, biting is not a behavior without reason; it is a form of communication. Children with autism may bite for various reasons, and with the right strategies, parents and caregivers can address and manage it effectively.

Once families understand the cause of the behavior and what they can do to prevent it, they can support their child in developing healthier ways to express themselves.

Why autistic children bite

Parents must understand why biting happens to address it effectively. Biting is not random; it is usually a response to an internal or external trigger. Here are common reasons autistic children may bite:

Sensory processing differences

Many autistic children’s brains interpret sensory input differently, causing sensory processing challenges. Some children bite for oral sensory

stimulation, while others may do so because they are overwhelmed by their environment.

Loud noises, bright lights, or certain textures might cause distress, and biting becomes a way to cope.
