YOUR QUESTION. A CLEARER NEXT STEP.
Is It Normal My Toddler Has No Externalizing Behaviors?
It is normal for a toddler not to show externalizing behaviours like hitting, biting or big tantrums — their absence is not a problem. Many children are simply easygoing or well-regulated. What matters more is steady growth in connecting, communicating, playing and exploring. Seek a developmental check not for absent tantrums, but if your child shows very little emotional expression of any kind, seems withdrawn, or has delays in talking and social connection. Early support, when needed, works beautifully.

If your toddler isn't pushing, hitting or having big outbursts, that's often a calm, settled sign — not something missing.
In short
Yes — it is completely normal for a toddler not to show externalizing behaviours like hitting, biting, throwing or big tantrums. These behaviours are common at this age, but their absence is not a problem; many children are simply easygoing, well-regulated, or express big feelings in quieter ways. Externalizing behaviours are something we watch when they appear and become intense or frequent — not a milestone your child must reach. What matters far more is steady growth in connecting, communicating, playing and exploring.
The science, gently
The word "externalizing" simply means feelings shown outwards — through actions like hitting, shouting or defiance. Between 12 and 36 months, the brain's self-control systems are still very young, so some outbursts are typical as words and emotions race ahead of regulation. But there is a wide, healthy range: a child who rarely melts down may have a gentle temperament, good early self-soothing, or a calm home rhythm. None of that is a concern.
Rather than counting tantrums, watch whether your child is moving forward overall:
- Connecting — seeking you out, sharing smiles, enjoying back-and-forth play.
- Communicating — using words, gestures, pointing, or responding to their name.
- Exploring — curious play, trying new things, showing preferences and protest in some way.
When a check is wise
Reach out for a developmental check not because tantrums are absent, but if you notice very little emotional expression of any kind, no protest or excitement, flat or hard-to-read responses, or delays in talking, social connection or play. A child who seems unusually withdrawn or unresponsive deserves a calm, early look.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
The absence of tantrums or outbursts is not a concern in itself. Seek a check if you notice very little emotional expression of any kind, no protest or excitement, flat or hard-to-read responses, an unusually withdrawn child, or delays in talking, social connection or play.
In everyday life
Notice how your toddler shows big feelings in their own way — a quiet pout, turning away, or coming to you for comfort all count as healthy emotional expression, even without loud outbursts.

Bring your questions to a first visitQuestions families ask
Should my toddler be having tantrums by now?
Not necessarily. Tantrums are common as self-control develops, but many easygoing or well-regulated toddlers have very few. Their absence alone is not a concern — what matters is overall growth in connecting, communicating and playing.
What are externalizing behaviours?
They are feelings shown outwards through actions — like hitting, biting, throwing, shouting or defiance. Some are typical in toddlers because emotions develop faster than self-control, but they are not a milestone every child must reach.
When should I be concerned about my toddler's emotions?
Reach out if your child shows very little emotional expression of any kind, rarely protests or shows excitement, seems unusually withdrawn or hard to read, or has delays in talking, social connection or play. These are reasons for a calm, early check — not a diagnosis.
