Why does my child bite other children?

I know that this can be really embarrassing for parents. Many times the child who bites is the victim and not the aggressor. A child who is being overpowered by other children physically often times bites in self-defense. Also, when language is delayed a child may bite out of frustration. Lastly, children teach each other to bite as well. The best thing to do is to absolutely forbid biting. If your child is being bullied you may want to talk to the teacher, send your child to karate, or if there's lack or supervision, change schools. If your child bites because he or she has difficulty expressing themselves you can help them express themselves. Phrases such as "I don't want you to do that", "I don't want to play right now", or any "I" message will help empower you child. He or she won't feel the need to bite.

Lastly, sometimes some children just feel like chewing or biting. Biting and chewing waxed lips, sugar free gum, or even a mouth guard can help with the desire to chew or bite.

Age-Appropriate Strategies for Responding to Biting

When biting occurs, gentle and consistent responses help your child learn alternative ways to express themselves:

Offer language: Kneel to your child’s level and calmly say, “You wanted that toy. You can say, ‘My turn, please.’” Giving them the words empowers them to communicate without their teeth.
Provide sensory alternatives: Keep teething rings, crunchy snacks, or chew necklaces available. Many toddlers bite simply because they crave oral sensory input.
Observe and redirect before it happens: Watch for signs of frustration, overstimulation, or hunger. When you notice tension building, gently guide your child toward a calming activity like water play or playdough.

Understanding the Developmental Context

Biting is a remarkably common behavior in children between twelve months and three years of age. During this stage, children experience intense emotions but have very limited verbal skills to express them. In Montessori philosophy, we recognize that the child is not being “bad” — they are communicating a need. With patience, modeling, and a prepared environment, most children move through this phase naturally as their language develops.

When to Seek Help

If biting persists beyond age three, increases in frequency or intensity, or is accompanied by other aggressive behaviors that disrupt your child’s daily life and relationships, consider consulting your pediatrician or a child development specialist. There is no shame in seeking guidance — it is simply another way of honoring your child’s needs.
