Key Takeaways

  • Studies show that untreated mental health conditions in infants and toddlers leave children more vulnerable to poor health, poor performance at school, criminal justice involvement, and even suicide.

  • Infants and toddlers may not always be able to talk about their mental health conditions, but they can show physical symptoms and behavioral changes that professionals are trained to notice.
  • There are many proven, cost-effective therapies that can help infants and toddlers recover from traumatic events and build their resilience.
Babies and toddlers can and do suffer from mental health problems caused by trauma, neglect, biological factors, or environmental situations.

Mental health is everyone's business

According to experts, around 1 in 10 children under the age of 5 experience mental health issues.

These can be the result of biological or environmental factors, or traumatic experiences such as witnessing violence, experiencing abuse or neglect, or surviving a natural disaster or accident.

Studies show that untreated mental health conditions in infants and toddlers leave children more vulnerable to poor health, poor performance at school, criminal justice involvement, and even suicide over time.

There are lifelong implications when things don’t go well, but as with physical health, positive input in these early years creates a strong foundation that can withstand storms.”

For infants and young children, mental health and physical health are intertwined, just as they are for adults.

Infants and toddlers may not always be able to talk about their mental health conditions, but they can show physical symptoms and behavioral changes that professionals are trained to notice. These symptoms can often be overlooked or dismissed, but experts are able to tell when these are early signs of something that could become a severe mental health issue in the future.

Symptoms of two common mental health issues in young children

While these behaviors tend to be present in many children, the key is to look for these signs of potential anxiety and depression in more of a collection than individually, with special attention to frequency, duration, and intensity.

Anxiety

  • Has significant difficulty sleeping, frequent night waking, bad dreams, and/or night terrors
  • Expresses frequent fears and worries around various activities (e.g., going outside, going to child care) or specific things (e.g., spiders, elevators, dogs).
  • Displays a short fuse with strong emotions—doesn’t have space between an upset and a full-blown tantrum
  • Is clingy and fussy beyond what seems typical for their age
  • Has a need to use the bathroom excessively once toilet trained, and/or other toileting struggles
  • Regresses or backslides in areas of previous skills
  • Frequently complains of stomachaches and not feeling well
  • Doesn’t meet developmental milestones as expected 

Depression

  • Lack of enjoyment in common activities
  • Sad and unresponsive facial expressions
  • Listless body posture
  • Slower physical mannerisms
  • Irritable and fussy
  • Trouble eating and sleeping
  • Unexplained physical aches and pains 

Treating mental health issues after child trauma

Even in the most challenging situations, consistent access to age-appropriate and specialized therapies can help children and their families thrive.

Because infants’ and toddlers’ brains grow so quickly, with intervention and consistent support from loving adults, they can often heal and thrive after traumatic incidents.

Success stories of trauma-informed IECMH care:

A military dad's PTSD
was impacting his ability to form a nurturing relationship with his 3-year-old after a long deployment, and his daughter was having outbursts and stopped speaking. With consistent access to specialized therapies, the relationship was restored, and the child is hitting developmental milestones once more.
After a hurricane hit her community
a 2-year-old girl was having significant nightmares that disrupt her sleep, refusing to eat, and at risk of losing a dangerous amount of weight. Her family, like many others, was dealing with profound loss. Consistent access to specialized therapy helped improve her physical health and allow her to developmentally thrive.
An 18-year-old living in a foster home
got pregnant at the end of high school. Without access to support, she experienced post-traumatic stress and depression, and self-medicated with illegal drugs. Her child was taken away and placed in foster care. Child-parent psychotherapy helped the mother and her child safely reunite and break the cycle of intergenerational trauma.
A 2-year-old was suffering from extreme neglect
– she was undernourished and had hearing loss from untreated ear infections. Her physical condition improved when she was placed with loving foster parents who wished to adopt her. But she still had night terrors and difficulty bonding with them. With specialized therapy, she was able to form healthy attachments to her new family and made the adoption a success.
A 2-year-old was sexually abused
by a family friend who would watch him while his parents were at work. His parents noticed their son would freeze around men and violently resist leaving the house. The family was given access to government-funded therapies. This allowed the child to begin to heal, helped his parents understand his distress, and restored the child’s trust in nurturing relationships.

Addressing mental health issues in young children builds healthy adults

There are many proven, cost-effective therapies that can help infants and toddlers recover from traumatic events and build their resilience.

These therapies are developmentally appropriate and focused on the needs of each child and their caregiver. Treatments include Child-Parent Psychotherapy and Parent-Child Interaction Therapy and are delivered by qualified mental health professionals. A specific focus on intergenerational trauma is often beneficial for families, as detailed by our 2024 LEARN Conference keynote speaker Dr. Mariel Buqué.

Therapies for infants and toddlers are more effective, save taxpayer dollars down the road, and are less intensive than addressing severe mental health issues later in life. Parent-Child Interaction Therapy saves an average of $1,159 per child in long-term educational, healthcare, and criminal justice costs.

We need to invest – as a country – in a specialized and diverse workforce of mental health professionals trained to work with infants and toddlers.
