Toddler Tantrums: Why They Happen & Montessori Strategies for Expat Parents

When your child throws themselves on the supermarket floor or screams until they turn purple, it feels like the world is judging you. But toddler tantrums are a normal part of brain development. They’re not manipulation or a lack of discipline: they’re how an immature brain processes emotions it can’t yet regulate.
Key Points
- Tantrums are a sign your child is feeling something they can’t manage alone.
- The frontal lobe, responsible for self-control, doesn’t mature until age 25; before that, the brain relies on the limbic system.
- Validating the emotion isn’t “giving in”: it’s teaching them their feelings matter.
- In Montessori, we accompany without rescuing or punishing: we observe, name, and wait.

What Really Happens in the Brain During a Tantrum
A tantrum isn’t a conscious decision by the child. When the brain’s amygdala detects a threat (not being able to eat cookies before dinner is a threat for a three-year-old), it activates the fight-or-flight response. The body floods with cortisol and adrenaline. The neocortex, which reasons, disconnects.
That’s why “reasoning” with a child in mid-explosion doesn’t work. They literally can’t hear you: their reptilian brain is in charge. The only thing that gets through is your calm presence, your tone of voice, and physical contact if they accept it.
The Window of Tolerance and Overwhelm
Psychiatrist Daniel Siegel explains that each person has an emotional “window of tolerance.” Outside of it, the nervous system becomes dysregulated. In young children, that window is narrow: anything can knock them out of it. Your job as an adult isn’t to close the window, but to accompany them until their body calms down again.

Why Tantrums Change with Age
A tantrum at 18 months is different from one at 5 years. At 18 months, the child is hungry, tired, or in pain and has no words to say it. At 3, they want autonomy: “I do it myself!” is their battle cry. At 5, there may be school or social frustration.
Understanding the age gives you the key to responding better. With a baby, you prioritize meeting physical needs. With a 4-year-old, you can start naming emotions and offering alternatives.

Toddler Tantrums at Age 2: The Peak Intensity
Between 18 months and 3 years, toddler tantrums reach their peak. The child discovers they are a separate person from mum, but they don’t have tools to manage that separation. They want everything and they want it now.
At this stage, daily tantrums of 10-15 minutes are normal. If they regularly last more than 25 minutes, consult your pediatrician to rule out sleep, feeding, or developmental issues.
What to Do During a Tantrum
Stay calm (I know it sounds impossible, but your regulation is their regulation). Get down to their level: squat, make gentle eye contact. Validate with few words: “You’re so angry because you wanted to stay at the park.” Don’t explain, don’t reason, don’t threaten.
If the child hits or bites, stop the action firmly but without violence: “I won’t let you hit. I’m here with you.” Offer physical alternatives: a cushion to hit, a hug if they accept it. If they don’t accept it, simply stay nearby in silence.

The Montessori Approach: Accompanying Without Rescuing or Punishing
In Montessori, we don’t use punishment or rewards because both externalize motivation. Instead of “I’ll take away the TV if you keep this up,” we say “I see you’re very sad. When you’re ready, we can talk.”
In the Children’s House classroom (ages 3-6) at IMS Sotogrande, guides do exactly this: they approach, name the emotion, and offer choices. The child learns that feeling angry is legitimate, but hitting isn’t. That distinction is the heart of Montessori emotional education.
Preparing the Environment as Prevention
Many tantrums are avoided before they start. In Montessori, we design environments that reduce the “no”: shelves at their height, accessible materials, clear routines. If the child can pour their own water, there’s no conflict over water.
At home, apply the same: put washed fruit on the low table, let them choose between two t-shirts, establish a visual morning routine with pictures. Every “yes” you build is a “no” you avoid.
How to Handle Tantrums in Public
The scenario that generates the most stress: your child screaming in the supermarket while other parents watch. First, remember no one is judging you as much as you think. Second, prioritize your child over strangers.
If you can, take them to a quieter place (the car, an empty aisle). If not, stay there with them. Don’t give in to the original demand (“buy the candy”), but don’t threaten consequences either. Simply accompany until it passes.
Later, at home, you can talk: “Today in the supermarket you felt very bad. What happened?” That later conversation is where real learning happens.
Common Mistakes That Worsen Tantrums
Punishing the emotion (“stop crying or go to your room”) teaches the child that feeling is dangerous. Giving in to the demand (“here, just stop”) teaches that screaming works. Both paths create more tantrums long-term.
It also worsens things to say “it’s nothing” when clearly something is happening. For a 3-year-old, their block tower falling down is something. Respecting that perspective is the first step to connecting.
When to Worry and When Not To
Tantrums are normal until age 5-6, though they decrease in frequency and intensity. If your child self-harms, has episodes lasting more than 30 minutes several times a day, or tantrums increase in frequency after age 4, consult a specialist. There may be anxiety, sensory regulation difficulties, or other needs.
If they’re simply having a bad day and screaming more than usual, breathe. Tomorrow will be different.
Frequently Asked Questions
Toddler tantrums are normal at age 2
Yes, tantrums are completely normal between 18 months and 4 years. The child is developing their identity and emotional regulation capacity. What they don’t have tools to manage, they express with their body: crying, screaming, meltdowns. It’s not a behavior problem; it’s a sign of healthy development.
Should I ignore my child’s tantrums
No. Ignoring a tantrum teaches the child their emotions don’t matter. What you should do is accompany without giving in to the original demand. You can say: “I’m here with you. When you calm down, we’ll talk.” The adult’s calm presence is what regulates the child, not punishment or indifference.
How do I know if my child has too many tantrums
If after age 4-5, emotional explosions are still daily, last more than 25 minutes on average, or include self-harm, it’s a good idea to consult a pediatrician or child psychologist. Also if they appear suddenly after a major change (move, birth of a sibling, separation). It’s not about alarming, but observing carefully.
Key Takeaways
Toddler tantrums are not a problem to be eliminated. They are an opportunity to teach your child that all emotions are valid, that you are there to support them, and that boundaries can be respected without violence. That’s the foundation of healthy emotional intelligence.
