A Former Pediatric Nurse’s Visual Framework for Teaching Kids the Mental Side of Puberty

Mood swings and emotional volatility have often been treated as unavoidable side effects of adolescence. Yet Karen Kearsley argues that they are better understood as signals of a developmental phase that has gone largely unexamined. 

The statistics strengthen that argument, as one in seven adolescents experiences mental health problems globally. And yet, when schools sit children down for puberty education, Kearsley highlights that the emotional health component of the curriculum often amounts to little more than a warning, condensed into a conversation about hormones and moodiness. 

The gap, she suggests, may leave children interpreting normal cognitive and emotional shifts as emotional failures. 

A pediatric nurse of twenty years, and founder of We-Shirts and Keysie, Kearsley has spent years watching what happens in the gap between that warning and the reality of adolescent emotional life. “They do a great job on teaching the physical and biological aspect of puberty, but when it comes to teaching the emotional side, all they may hear is surface-level information; that’s the extent of it,” Kearsley says. This, she notes, can cascade into a growing confusion among children and teenagers, who may struggle to articulate what is happening in their own minds. 

Her response is a framework, called Mental Puberty, built around a visual map she refers to as the Inner 5. 

The model identifies five internal senses, including judgment, loss and sorrow, humor, adventure, and love. Kearsley explains that the emotions are positioned as counterparts to the five physical senses children already understand. “We all know the outer five senses. But similarly, we also have an inner five. And if children don’t learn how those work, they’re left guessing why they feel the way they feel,” she says. 

Far from abstract, each inner sense has a physical location in her visual map, which appears as a brain-shaped lobe, color-coded, and spatially arranged to indicate how they relate to one another and to emotional states. 

According to Kearsley, they are divided into “sunny” and “cloudy” regions. The sunny side, she notes, corresponds to emotions associated with curiosity, connectedness, and joy. The cloudy side reflects judgment, distress, and perceived loss. In her view, the “sunny” regions often dominate during childhood. 

Adolescence, then, she notes, marks a fundamental shift. 

“The cloudy side starts expanding,” she says. “But that’s not a problem. It’s the brain preparing itself to make logical adult decisions, to assess risk, to think about consequences. But if no one explains, it feels like something is going wrong.” 

Kearsley’s emphasis on visualization aims to address what she sees as a core limitation in existing approaches, which may rely on verbal explanation and intangible concepts. She argues that children are expected to internalize language that may not yet align with their cognitive development. “You’re asking them to process invisible ideas with no map. With our visual map, if they can point to where they are in their thinking, it could become manageable,” she explains. 

The Inner 5 framework also reframes emotional discomfort. Kearsley explains how academic pressure, social exclusion, or even the loss of free time can activate the same internal mechanism as loss. 

“A 40-page paper can feel like a loss,” she explains. “It’s time taken away from what you want to do. You can sit in that and spiral, or you can shift it, toward the adventure sense, toward reframing the paper as a project you own, toward finding the yellow side again. That’s a skill.”

Her purpose-driven work further extends into product design. We-Shirts, one of her flagship initiatives, functions as a physical tool to facilitate peer interaction. Attached to a backpack or worn on a lanyard, the device contains three customizable prompt cards: “I like,” “my favorite,” and “something else about me.” The holder, she notes, stays closed until someone asks to see it. “You have to ask,” she says. “It creates a moment where one child approaches another and starts a conversation without pressure.”

The design of the product reflects her broader critique of the social-emotional learning models that remain confined to instructions. “Trying to teach social skills without real instructions is like teaching swimming in a classroom. Kids need a setting where they actually engage, where they experience that initial awkwardness and move through it. That’s how they build a community,” Kearsley explains. 

Research consistently shows that belonging is protective. Studies have found that adolescents who reported higher school belonging and connectedness had significantly lower mental health symptoms across young adulthood. Kearsley’s work operates exactly in that space, and it operates with tools. 

Parental involvement plays another central role in her strategy. Kearsley intends to introduce the framework to adults first, positioning them as reinforcers of the model at home. Overprotection, she argues, has unintentionally limited children’s exposure to necessary emotional experiences. 

“Parents want their kids to be happy all the time,” she says. “So they remove obstacles, they solve problems. Then puberty hits, and suddenly the child has to make decisions, sit with discomfort, and figure things out. They’ve never practiced.”

Through her framework, she explains that children can be guided to recognize emotional states without immediate intervention, allowing them to build tolerance and self-direction. “They need to learn that feeling uncomfortable doesn’t mean something is wrong. It means something is changing,” she says. 

Kearsley is currently developing e-books, refining her presentation for parent-teacher organizations, and building out the Inner 5 as a framework she hopes will one day sit alongside the outer five senses in every curriculum. The goal, she emphasizes, isn’t to replace clinical care, but to give children and their parents a common shared language before a crisis ever arrives.
