If You’re Trying to Change Your Child’s Temperament, You’re Doing It Wrong. ‘Raising Good Humans’ Explains Why

There’s no universal parenting playbook—and that’s probably a good thing. Every child shows up with their own wiring, and understanding that wiring can transform how families navigate everything from bedtime routines to social situations. On Raising Good Humans, host Dr. Aliza Pressman and developmental psychologist Dr. Koraly Pérez-Edgar dive into why temperament plays such a crucial role in how kids grow, adapt, and thrive. The key insight: Temperament isn’t something to fix—it’s something to work with.

As Pérez-Edgar explains, temperament is the “biological basis” of personality. It shows up early and shapes the way kids respond to the world, whether they’re the life of the party or the quiet observer in the corner. But biology isn’t destiny. Parents and teachers can scaffold, support, and guide children in ways that honor their temperament without trying to fight it.

Temperament sets the blueprint—parents build the house

Temperament is “biologically based…early appearing, and…relatively stable across contexts,” Pérez-Edgar explains. But that doesn’t mean your child’s path is locked in. Instead, temperament functions like a blueprint. Some children are naturally cautious and slow to warm up, while others charge ahead with little fear. Neither is better, but each requires different parenting strategies.

Think of it as building a home. The blueprint outlines the foundation, but parents choose how to construct the walls, fill the rooms, and make it livable. A shy child may benefit from smaller, scaffolded steps into new situations—practicing a presentation with a parent before facing classmates or visiting a new playground during off-peak hours first. An exuberant child might need structured, safe outlets for their energy, like sports or creative projects, so that their boldness grows into confidence rather than recklessness.

“It’s not deterministic,” Pérez-Edgar explains. “We know that parents and children tend to share traits. We can say it runs in the family. Whether we tend to be shy, we tend to be outgoing.” The foundation influences what’s possible. Parents can’t swap one blueprint for another, but they can build with intention.

There’s no “best” temperament

Parenting culture often idealizes the “easy baby”—the one who adapts quickly, rarely fusses, and goes with the flow. But as Pressman points out, “There isn’t one better temperament. There might be an easier one.” Easy doesn’t mean superior, and challenging doesn’t mean deficient. A reserved child, for instance, may form deep, lasting friendships and show remarkable empathy. A high-energy child might test limits but also grow into a resilient leader who isn’t afraid of challenges. Each temperament carries strengths and vulnerabilities, and the role of a parent is to support both sides.

What matters is resisting the urge to compare. Two siblings raised in the same home can have radically different temperaments. Rather than trying to mold them into a single “ideal,” Pérez-Edgar encourages parents to recognize the value of each. 

Why your calm is contagious

One of the most fascinating findings from Pérez-Edgar’s research is how children quite literally sync with their parents. “Our brain waves become more synchronized, our heartbeats become more synchronized,” she says, describing how biological signals align during shared activities. In studies, kids tackling stressful puzzles with their parents showed higher synchrony—especially in kids still developing their own self-regulation skills. 

This has big implications for everyday life. When a child is nervous before a school play or overwhelmed by homework, a parent’s calm presence does more than reassure—it helps regulate their biology. Your steadiness becomes a model and a resource, one your child can draw from while building those skills themselves. However, this synchrony works both ways. Pérez-Edgar cautions that syncing with an emotionally unregulated adult can intensify stress. As children grow, they need to lean less on their parent’s nervous system and more on their own.

Let go of perfection

If children bring blueprints, parents bring their own personalities to the table—and the two don’t always match. Researchers call this the “goodness of fit.” Pérez-Edgar explains that a good fit doesn’t mean being mirror images—it means being sensitive and attuned.

An outgoing parent may need to slow down and respect a child’s hesitancy, while a reserved parent may be stretched by a child who thrives on constant social activity. Neither pairing is wrong, but problems arise when parents push children to conform to their own comfort zone rather than adapting to theirs. A parent who insists, “I loved meeting new kids, so you should too,” risks overlooking what a cautious child needs to succeed. Conversely, telling an adventurous child to stop being “too much” can dim their natural spark.

When parents stop searching for the “perfect” temperament and start supporting the one their child actually has, everything shifts. The shy child learns to face the world with quiet courage, the bold child learns to direct their energy wisely, and both learn that they’re accepted for who they are.
