What is the "Terrible Twos"? Symptoms, Causes, and Advice for Parents

The "terrible twos" is a term used to describe a developmental stage, typically occurring between 18 months and 3 years of age, when children begin to express their own desires. It is not a medical condition or a psychological disorder.

During this period, children begin to realize they are individuals and want more control over their environment. However, because their ability to manage their emotions and express themselves verbally is not yet fully developed, they may occasionally exhibit temper tantrums, crying spells, and stubborn behavior.

What Are the Symptoms of the Terrible Twos?

Every child experiences this process differently. While symptoms may be mild in some children, they can be more pronounced in others.

The most common symptoms include:

  • A tendency to constantly say "no"
  • Stubbornness
  • Temper tantrums
  • Crying spells
  • Throwing themselves on the floor when they don't get their way
  • Throwing toys or objects
  • Impatience
  • Wanting to do everything by themselves
  • Wanting to make choices regarding clothing, food, or play
  • Testing the boundaries set by parents

These behaviors are, for the most part, a natural part of the developmental process.

What Causes the Terrible Twos?

During this period, children's brain development and social skills advance rapidly. While children want to make their own decisions and act independently, they still require adult support for their safety and development.

The primary factors contributing to the emergence of the terrible twos are:

  • An increased desire for independence
  • Underdeveloped ability to express emotions
  • Language skills not yet sufficient to fully communicate needs
  • Changes in routine
  • Hunger, fatigue, or lack of sleep
  • Overstimulating environmental conditions

How Should Temper Tantrums Be Managed During the Terrible Twos?

Temper tantrums are one of the most common behaviors during this period. A calm and consistent approach from parents helps manage the process more easily.

The following approaches are recommended during a tantrum:

  • Make an effort to stay calm.
  • Avoid shouting or using physical punishment.
  • Ensure the child's safety.
  • Give them the opportunity to express their emotions.
  • Do not engage in long arguments during the tantrum.
  • Communicate with love once the tantrum has ended.

Trying to understand the intense emotions the child is experiencing contributes to maintaining a sense of security.

How Should Parents Behave During the Terrible Twos?

A consistent and patient approach is of great importance during this period.

Recommendations for parents:

  • Establish clear and understandable rules at home.
  • Ensure that all caregivers apply the rules in the same way.
  • Offer your child age-appropriate choices. For example, asking "Would you like to wear the blue t-shirt or the green one?" can help support their decision-making skills.
  • Notice and praise positive behaviors.
  • Maintain daily routines as much as possible.
  • Give your child the opportunity to take on age-appropriate responsibilities.

What to Avoid During the "Terrible Twos"

Certain attitudes can cause behaviors to intensify.

Behaviors to avoid include:

  • Yelling or making threats
  • Using physical punishment
  • Constantly saying "No"
  • Giving in to every request
  • Changing rules frequently
  • Comparing the child to other children

Inconsistent approaches can make it difficult for a child to understand boundaries.

How Long Do the "Terrible Twos" Last?

For most children, this is a temporary developmental phase. Symptoms often begin around 18 months, become more pronounced around age 2, and gradually decrease by age 3 or 4.

The duration can vary depending on the child's developmental characteristics, temperament, and parenting approach.

When Should You Seek Professional Help?

It is recommended to consult a pediatrician or a child and adolescent psychiatrist in the following situations:

  • Temper tantrums that are very frequent and long-lasting
  • The child harming themselves or others
  • Significant delays in speech and developmental milestones
  • Experiencing serious difficulties in social communication
  • Behaviors significantly impacting daily life
  • Parents struggling to manage the process
