Therapy that supports externalizing behaviours in toddlers
Externalizing behaviours in toddlers — hitting, biting, throwing and intense tantrums — are best supported through parent-led behaviour therapy and positive-parenting coaching that teach warm, consistent responses, alongside play-based regulation and early communication support. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.

When a toddler hits, throws, or melts down, the right gentle support can turn big feelings into early self-control — and calmer days for the whole family.
In short
Externalizing behaviours in toddlers — hitting, biting, throwing, intense tantrums — are best supported through parent-led behaviour therapy, especially approaches like Parent–Child Interaction Therapy (PCIT) and positive-parenting coaching. These teach you warm, consistent responses that help your child learn to manage frustration and express needs in safer ways. At this age the goal is never to label a child, but to build the early skills of self-regulation through play and steady routines.
The support that helps
- Parent coaching and behaviour therapy — the core support. A therapist shows you how to praise the behaviour you want, set calm and clear limits, and respond consistently so your toddler learns what works.
- Play-based regulation work — naming feelings, calming games and predictable routines help a child handle big emotions before they spill over.
- Speech and communication support — many toddlers act out because they cannot yet say what they need; building early words and gestures often reduces frustration directly.
- Teacher and caregiver alignment — the same gentle, consistent approach at home and at daycare helps skills stick.
At 12–36 months, some pushing of limits is completely normal development. Support focuses on giving your child — and you — the tools to turn frustration into communication.
When to seek a check
If aggression or tantrums are frequent, intense, hard to settle, or affecting daily life and relationships, a developmental check helps a clinician understand what's driving the behaviour and shape the right support.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Watch for frequent or intense hitting, biting or throwing, tantrums that are very hard to settle, behaviour that hurts the child or others, or difficulties spilling across home and daycare.
In everyday life
Catch the good moments — warmly praise the specific behaviour you want ('lovely gentle hands!') far more often than you correct, and keep daily routines predictable so big feelings have less to push against.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
Is hitting and throwing normal in a toddler?
Yes — some pushing of limits, hitting and tantrums is a normal part of development between 12 and 36 months, when language and self-control are still growing. Support helps when these behaviours are very frequent, intense or hard to settle.
What is the main therapy for externalizing behaviours?
Parent-led behaviour therapy — including approaches like Parent–Child Interaction Therapy and positive-parenting coaching — is the core support. It teaches warm, consistent responses that help a toddler learn to manage frustration safely.
Can speech delay cause behaviour problems?
Often, yes. Many toddlers act out because they cannot yet say what they need. Building early words and gestures frequently reduces frustration and aggression directly, so communication support is part of many plans.
