Frequent crying, tantrums, or sudden mood swings in children do not mean they have a bad temperament. These behaviors are often signs of an immature emotional regulation system.
The Brain Behind Emotions: Prefrontal Cortex & Amygdala
Emotional stability depends on the coordination between the prefrontal cortex (responsible for rational thinking) and the amygdala (which governs emotional responses). When these connections are still developing, children tend to react more strongly to minor triggers.

Common Causes of Tantrums
Several factors can make children more prone to emotional outbursts:
- Poor sleep or irregular routines
- Daily stress or sensory overload
- Weak attention and ongoing brain development
- Tense family atmosphere
- Lack of essential brain nutrients like omega-3, lutein, and B vitamins
Why Ages 0–12 Matter
The first 12 years are critical for the development of the brain’s emotional system. With proper nutrition, support, and guidance, children can gradually learn self-regulation and manage their emotions more effectively.
Supporting Your Child’s Emotional Growth
By understanding how the prefrontal cortex and amygdala work, parents can approach tantrums with patience and scientific strategies, helping their children develop emotional resilience and confidence.
