Why even babies and children can become depressed

While it’s mostly adults who suffer from mood disorders, even babies and children can experience depression. However, it may display itself differently than in grown-ups.

Depression in young children often manifests through behavioral and emotional changes rather than verbal expressions of sadness or despair, as they may not yet have the language or self-awareness to describe their feelings.

Signs of depression in babies and toddlers:

1. Persistent sadness or irritability

• • Frequent crying or fussiness without an obvious cause.

• • Seeming withdrawn or less responsive to stimulation.

2. Changes in appetite or sleep patterns

• • Trouble sleeping or snoozing too much.

• • Loss of appetite or feeding difficulties.

3. Loss of interest in play or exploration

• • Reduced engagement with toys, games, or people.

• • Appearing inactive or uninterested in the environment.

4. Flat affect

• • Lack of emotional expression, such as rarely smiling or laughing.

5. Delayed developmental milestones

• • Slower progress in language, motor, or social skills.

Signs of depression in children (preschool age and older):

1. Mood changes

• • Persistent sadness, irritability, or misery.

• • Frequent temper tantrums or disproportionate frustration.

2. Social withdrawal

• • Avoiding friends, family, or social activities they previously enjoyed.

3. Physical complaints

• • Frequent stomachaches, headaches, or other unexplained physical symptoms.

4. Changes in sleep and appetite

• • Sleeping too much or too little.

• • Changes in eating habits, such as eating too much or too little.

5. Low energy or fatigue

• • Seeming tired or lethargic, even after seemingly sufficient rest.

6. Difficulty concentrating

• • Trouble focusing on tasks, schoolwork, or activities.

7. Self-destructive behaviors

• • Engaging in risky behaviors or talking about wanting to hurt themselves (in older children).

8. Academic or behavioral problems

• • Declining school performance or increased behavior issues.

Causes and risk factors of depression in children:

Depression in children can result from a combination of genetic, biological, environmental, and psychological factors, just as it can in adults.

Stressful life events, family conflict, trauma, or a family history of mood disorders can increase the risk of becoming depressed.

1. Biological factors:

• • Genetics

• • • A family history of depression or other mood disorders increases the likelihood of a child developing a mental illness.

• • • Specific genetic predispositions related to neurotransmitter regulation, like serotonin or dopamine.

• • Brain chemistry and neurodevelopment

• • • Imbalances in neurotransmitters such as serotonin, norepinephrine, and dopamine.

• • • Disruptions in brain regions that are associated with emotion regulation (the amygdala, prefrontal cortex).

• • Prenatal and perinatal factors

• • • Maternal depression, anxiety, or stress during pregnancy can affect fetal brain development.

• • • Birth complications, low birth weight, or premature birth could increase vulnerability.

• • Chronic illness or pain

• • • Children with chronic medical conditions (asthma, diabetes, epilepsy) are at higher risk due to the psychological strain and limitations imposed by their condition.

• • Hormonal changes

• • • Though more relevant to older children and adolescents, hormonal shifts (during puberty or due to endocrine disorders) may influence mood.

2. Psychological factors:

• • Attachment issues

• • • Insecure or disrupted attachment to caregivers, especially during infancy, can lead to emotional dysregulation and depression.

• • • Early neglect or inconsistent caregiving can result in feelings of insecurity or mistrust.

• • Temperament

• • • Babies and children with a naturally sensitive or anxious temperament are more prone to internalizing stressors and experiencing depressive symptoms.

• • Trauma or adverse childhood experiences (ACEs)

• • • Physical, emotional, or sexual abuse.

• • • Witnessing domestic violence or substance abuse within the household.

• • • Experiencing or witnessing a traumatic event, such as a natural disaster or car accident.

• • Grief and loss

• • • Death of a parent, sibling, or close caregiver.

• • • Loss of a pet or an important figure in their life.

• • Low self-esteem

• • • Repeated experiences of failure or rejection, even in early childhood, can make us feel inadequate and cause depression.

3. Environmental and social factors:

• • Parental mental health

• • • Living with a parent who has untreated depression, anxiety, or other psychological issues.

• • • Exposure to inconsistent or unpredictable parenting due to mental illness or substance abuse.

• • Stressful life events

• • • Moving to a new location, starting a new school, or separation from a primary caregiver.

• • • Parental divorce, custody disputes, or family instability.

• • • Financial hardship that creates stress in the household.

• • Peer relationships

• • • Bullying or social rejection at school or daycare.

• • • Difficulty making or maintaining friendships.

• • Cultural or social pressures

• • • Socioeconomic disadvantage or living in a marginalized community.

• • • Exposure to systemic racism, discrimination, or prejudice.

• • • Pressure to conform to cultural or familial expectations.

• • Environmental stressors

• • • Living in a chaotic or unstable environment (overcrowded housing, unsafe neighborhoods).

• • • Experiencing displacement or living in a refugee or migrant situation.

4. Developmental and behavioral factors:

• • Delayed development

• • • Developmental delays in speech, motor skills, or social skills may lead to frustration and failure.

• • • Conditions like autism spectrum disorder (ASD) or ADHD increase vulnerability to depression due to social challenges and misunderstandings.

• • Parent-child relationship issues

• • • Harsh discipline, excessive criticism, or lack of emotional warmth from caregivers.

• • • Overly high expectations or perfectionistic parenting.

• • Overexposure to negative media

• • • Frequent exposure to distressing news, violent content, or age-inappropriate material may affect a child’s sense of safety and emotional well-being.

5. Physiological and sensory factors:

• • Sensory processing difficulties

• • • Overwhelming sensory environments (loud noises, bright lights) may lead to chronic tension and emotional withdrawal in children with sensory sensitivities.

• • Sleep disruptions

• • • Chronic sleep deprivation or poor sleep hygiene can influence emotional regulation and aggravate mood disorders.

• • Dietary factors

• • • Nutritional deficiencies (vitamin D, iron, omega-3 fatty acids) have been linked to mood disorders.

• • Exposure to toxins

• • • Lead poisoning or exposure to environmental pollutants can upset brain development and increase the risk of mood disturbances.

How these genetic, biological, environmental, and psychological factors interact:

Depression in children often results from a combination of the above factors, rather than a single cause.

For example:

• A child with a genetic predisposition to depression might be more vulnerable to the effects of parental divorce or bullying.

• A stressful environment can degrade an already sensitive temperament.

What to do:

This is what to do if you suspect a baby or child is showing signs of depression:

1. Consult a pediatrician

Rule out underlying medical issues and get the necessary guidance.

2. Seek a child psychologist or therapist

A mental health professional can assess and provide therapy or interventions if needed.

3. Offer supportive parenting

Maintain a nurturing, stable environment, and encourage open communication.

4. Monitor changes

Keep track of behaviors, sleep, and eating patterns to share with professionals.

Conclusion

Quick action, whether through therapy, parenting support, or environmental changes, aids in mitigating the long-term impact of depression on a child’s emotional and social development.

That’s why early recognition and intervention are so important in helping young children overcome depression and build emotional resilience.
