The Impact of Childhood Instability on Early Brain Development

Too Small to Fail

Young children need nurturing and stable environments in order to thrive, but many experience instability and high levels of stress as a result of sudden family changes like divorce or job loss. In this factsheet, we outline the ways in which instability can be damaging to a child’s early development, and provide concrete suggestions for how parents can lessen the impact and support their kids through tough times.

Childhood instability, as defined by the Urban Institute’s recent important report on the topic, refers to sudden and involuntary disruptions in a child’s life that cause a negative change.1 Instability can manifest in many overlapping ways. For instance, a child may experience instability from a job loss in the family as well as the subsequent financial hardships that it brings. 

Why is it important?

Early childhood experiences form the building blocks of a child’s lifelong health and development. The science tells us that: 

In the first two years, a child forms an average of 700 neural connections per second, and by the age of 6, her brain will have already reached about 90 percent of its adult capacity.23

Nurturing environments and secure, stable relationships with adults help children thrive and contribute to their cognitive, social, and emotional development.4

Young brains are like sponges: they absorb an incredible amount from their environment. The technical term is “neural plasticity,” and while some level of plasticity exists in adulthood, early childhood is when the brain is most malleable.5 The presence of negative stimuli in a child’s environment – such as poverty, emotional or physical abuse, and violence – can be damaging to a child’s long-term development.6

Is all instability damaging?

Not all instability is damaging. According to the Center on the Developing Child at Harvard University, whether or not an event has long-term effects on a child depends in part on the level of stress it introduces:

Positive stress is normal and even necessary. We experience this type of stress response routinely. For a child, this may be the anxiety that arises before receiving a vaccine at a doctor’s visit.

Tolerable stress arises out of more serious circumstances. For a child, this could mean coping with the loss of a family member. It is tolerable when the child is supported by nurturing, caring adults.

Toxic stress occurs when a child experiences extreme adversities without an adequate buffer. It arises from frequent exposure to violence, abuse, or neglect. Stress from other sources, like chronic financial hardship, can also become toxic if the child is not adequately supported by an adult.

Children who face stress equipped with a supportive environment and stable relationships are likely to develop a healthy stress response system. Children who are unsupported by a consistent adult and who experience extreme and prolonged stress are at risk of long-term damage to health and development. Children exposed to toxic stress are at a greater risk for poor health outcomes such as heart disease and depression in adulthood.7

What can parents do?

Families are often confronted with stressful challenges that are beyond their control. But there are many ways parents can ameliorate the impact of stress and instability on children and support critical early development.

  • Reassure your child

What is most helpful to your child during tough times is your reassurance and extra attention so that they can feel secure. Even a small act like hugging your child more or saying to your child “Everything will be O.K” can provide that reassurance.8

  • Take a breath

Children pick up on parental stress, using that sponge brain of theirs. Recognizing and managing your own stress not only helps you cope better, but it also minimizes the stress your child will feel.

  • Bond with your child

Children with strong bonds to their parents have an advantage when stressful situations present themselves. As children develop, how their parents respond to their needs shapes their emotional, mental and social well-being.9

  • Establish routines

Routines and consistency facilitate your child’s learning and development, and contribute to a stable environment that will help your child thrive. A standard bedtime, for example, has been shown to have positive benefits for cognitive development and health.10
