Therapy techniques that help a child who bites

Biting is rarely about defiance — it is communication a child cannot yet put into words, and the right techniques translate that message into safer skills.

In short

Biting in young children is most effectively addressed through functional behaviour analysis — identifying why the child bites (sensory input, frustration, communication breakdown, teething or escape from demand) — and then teaching a replacement skill that meets the same need. Evidence-led techniques combine antecedent strategies, functional communication training, oral-sensory regulation and consistent caregiver coaching. The goal is never punishment but to give the child a safer, faster way to express what the bite was trying to say.

The techniques that help

• Functional behaviour assessment (FBA) — observe and chart antecedents, behaviour and consequences (the ABC framework) to establish function: sensory-seeking, communicative, escape/avoidance or self-regulatory. Every other technique flows from this.
• Functional communication training (FCT) — teach a developmentally matched replacement: a sign, a picture exchange, a single word or AAC output for stop, help, more or break. Reinforce the replacement immediately and densely so it out-competes the bite.
• Antecedent modification — adjust the environment to reduce triggers: shorten waiting, signal transitions, reduce crowding and proximity-related frustration, and pre-empt demand fatigue with built-in breaks.
• Oral-sensory strategies (OT-led) — for sensory-driven biting, offer appropriate chewable input (chewy tubes, textured foods, vibration) and a sensory diet so the child's proprioceptive oral needs are met proactively rather than through skin.
• Differential reinforcement (DRA/DRO) — reinforce alternative or incompatible behaviours and acknowledge intervals without biting, building a robust schedule of positive feedback.
• Caregiver and educator coaching — consistency across home and setting is the single strongest predictor of generalisation. Teach calm, low-affect responses that avoid inadvertently reinforcing the bite with dramatic attention.

When to refer

Refer for structured assessment when biting is frequent, intensifies, causes injury, persists beyond the toddler stage, or co-occurs with delayed expressive language, marked sensory differences or wider social-communication concerns. Sudden behavioural change, regression or biting alongside developmental loss warrants prompt paediatric review.

The Pinnacle way

AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app or checklist. Our clinician-administered structured assessment maps the function behind the behaviour and the child's communication and sensory profile, then shapes a plan delivered through behaviour and developmental therapy and, where indicated, speech and language therapy for the communication piece. Learn how the AbilityScore® is formed, and explore the wider network at Pinnacle Blooms Network.
