Why does a 2-year-old baby like to shout and scream?

A 2-year-old child's tendency to shout loudly may be due to physiological factors, or it could result from pathological conditions such as hyperactivity disorder or tic disorder.

I. Physiological Factors

Two-year-old children have not yet fully developed their language abilities and can only use simple words. When they urgently want to express their emotions but are not understood by caregivers, they may resort to shouting as a way to release their frustration. Parents should engage in frequent communication with the child to promote language development and help alleviate this behavior.

II. Pathological Factors

1. Hyperactivity Disorder (ADHD)

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental condition. Abnormal development of the frontal lobe or asymmetrical development of the caudate nucleus can lead to emotional instability and excessive excitement, resulting in loud shouting. It is recommended to seek medical evaluation and, under a doctor’s guidance, consider psychological interventions. If necessary, medications such as methylphenidate hydrochloride tablets or atomoxetine hydrochloride capsules may be prescribed to improve attention deficits and reduce hyperactivity and impulsive behaviors.

2. Tic Disorder

Tic disorder is a type of delayed-onset neurological condition, usually caused by an imbalance of central neurotransmitters in the brain. During episodes, children may exhibit repetitive, irregular, and varied motor tics involving multiple body parts, along with involuntary vocalizations or uttering inappropriate words. Regular communication with the child to maintain a relaxed mood and avoid emotional excitement is important. If needed, under medical supervision, medications such as haloperidol tablets, paroxetine hydrochloride tablets, or tiapride tablets may be used to block dopamine receptors in the brain and help control symptoms.

In addition, epilepsy could also be a potential cause. It is advisable to visit a hospital for appropriate diagnostic evaluations, determine the exact cause under medical guidance, and receive targeted treatment accordingly.
