Is It Laziness or Something Else? What Parents Should Know About Executive Function by Age

After looking for your child’s favorite hoodie for the umpteenth time, you’d swear that they would lose their head if it weren’t attached to their body. But sometimes, a kid can’t help that they find it hard to start their homework or forget that they have band practice after school. And in your kiddo’s case, there may be a name for it: executive function.

Since it affects so many areas of your child’s life, it’s important to know what executive function is (and isn’t) and what you can do as a mom to help support the development of this very specific skill set.

What Is Executive Function?

Your child insists that their Girl Scouts meeting is on Sunday, when it was actually on Saturday. Their room is always a mess — and their focus? Forget about it. (Ha.) Keeping everything functioning is something many kids struggle with, and more often than not, it’s an executive function issue. 

“Executive function is a set of mental skills that help individuals manage their thoughts, actions, and emotions,” explains Brooke Sundin, LMFT, a Licensed Marriage and Family Therapist at Light Minds Child and Family Therapy Inc. “It can be thought of as the brain’s ‘project manager’ by helping you organize, prioritize, and guide how tasks are done.” While executive function doesn’t do the heavy lifting for you, it can offer the best way to manage the mental load.

Executive function skills include your working memory (like being able to remember and retain the name of the class mom), impulse control (i.e. not getting lost in a show when you’re supposed to be loading the dishwasher), and cognitive flexibility (such as being able to suddenly switch gears when necessary—i.e. bolt out of a meeting when the school nurse calls and says your kid puked in class).

Your child might have certain goals — like completing a reading challenge at school — but it’s their individual executive functioning that determines if they can achieve them. “When executive function is working well, kids can pause, think, choose, and follow through; when it’s lagging, they often know what to do but can’t consistently do it,” explains Amanda Armstrong, M.Ed., an educator and founder of Insight Education Academy. And the glue that keeps it all together — being able to manage their emotions. “Self-regulation is a crucial area of executive functioning because it links all the skills together.”

How Does Executive Function Vary By Age?

Executive function stems from the prefrontal cortex. As its name suggests, the prefrontal cortex is located in the front part of your brain that sits right behind your forehead. But executive function isn’t static or set in stone — it continuously develops as your child gets older. “The prefrontal cortex is one of the last parts of the brain to fully mature,” says Sundin. “The development of the prefrontal cortex begins during toddlerhood and continues into the mid-twenties.”

Since it’s ever-evolving, EF greatly varies by age, but it still focuses on the themes of organization, decision-making, time management, and emotional and behavioral regulation.

“Executive function develops slowly from early childhood through the mid‑20s, with huge variation between children,” says Sundin. 

How Executive Function Varies by Age

Here are some ways in which executive function varies based on age:

• Early childhood (3–5): At the onset of executive function, skills include understanding and following simple directions. “We’re looking for beginnings, not mastery,” says Armstrong. “A child should be able to wait a short turn, follow a simple two‑step direction, or shift from playtime to cleanup with help.”
• Early elementary (6–8): Building on the skills they’ve learned in early childhood, kids continue strengthening their executive function skills. “At this stage, executive function looks like organizing materials, completing homework, and transitioning between activities.” Armstrong adds that kids may begin using strategies to help them create next steps or using visual schedules to keep themselves on task. 
• Upper elementary (9–11): Consistency is key for this age group, where kids become more independent and need less parental input on how and when to get things done. “We expect more consistent follow‑through on multi‑step tasks, basic time awareness (‘i.e. ‘I have 10 minutes left’), and the ability to start homework with some prompting.”
• Middle school (11–14): Here’s where your child’s executive function skills start to shine. School projects are planned over days — and not the night before it’s due. Says Armstrong: “They should also have the ability to keep track of assignments, break projects into pieces, and switch between classes with many different expectations.”
• High school and beyond (14+): Independence is the skill that defines this age group, according to Sundin. “We refine long‑term planning, prioritizing, and self‑monitoring (noticing when a plan isn’t working and adjusting),” she says. “Even into college and young adulthood, these skills are still very much under construction.”

What Are Some Signs That Your Child May Have An Issue With Executive Function?

You drop your child off at school and see that they left their water bottle in the cup holder — again. Or your kiddo constantly starts playing with the cat when they’re supposed to be taking a shower. It’s normal to sometimes be distracted or struggle with starting an assignment, but when your child repeatedly experiences these issues, they might have executive function difficulties. 

“Your child may have trouble starting tasks, repeatedly losing items, or have challenges with perspective taking,” says Sundin. And time management is one of the top indicators of executive function. “They may have difficulty managing time effectively and struggle with multi-step directions that peers their age handle more easily.”

Signs Your Child May Struggle With Executive Function

If you’ve noticed your child exhibiting some of these signs, executive function struggles can be the cause, according to Armstrong:

• Chronic “forgetfulness”: repeated lost items, missed assignments, or incomplete tasks despite reminders.
• Big gap between verbal ability and output: a child who can explain their ideas but can’t get them on paper or turn work in.
• Trouble starting tasks: “staring” at homework, cleaning, or projects, even when they know what to do.
• Meltdowns around transitions or multi‑step directions.
• Constantly running late or underestimating how long things will take.
• Rooms, backpacks, or digital spaces that are relentlessly disorganized, even after organizing “resets.”

But executive function isn’t just about your child missing their math assignments — feelings also accompany EF challenges. Anxiety may also be a sign of something deeper.

“Executive function struggles are often accompanied by increased anxiety,” says Sundin. “For example, a child who avoids starting homework may appear disorganized but may also be worried about making mistakes or getting a bad grade,” she says. 

And it’s not about laziness, either. “These patterns, especially when they show up across settings such as home and school, are more about brain wiring than willpower,” says Armstrong. “If a child consistently cannot do what peers can — even with support — it’s a sign to look more closely at executive function rather than assuming they’re unmotivated.”

What Interventions Can Help With Executive Function Issues?

Helping your child spruce up their executive function skills isn’t as simple as telling them to remember their rugby schedule or complain when they don’t load the dishwasher. Building executive function skills should be age-based in order to create a solid base. 

Younger children often learn through play, so naturally, games are a great way to get them learning without even realizing it. “Games and structured activities build executive function skills in a fun, low-pressure way, so it doesn’t feel like work,” says Sundin. “Through play, children practice skills such as planning, working memory, and cognitive flexibility.”

For example, games like Red Light, Green Light, and Freeze Dance encourage your kid to stay focused as well as suddenly switching from staying put to running.

With older children, developing strategies that include your child’s natural strengths is important. “The most effective approaches combine environmental supports with skill‑building,” says Armstrong. “Use visual schedules, checklists, color‑coding, alarms, and written routines, so children don’t have to hold everything in their heads.”

Here are more ways to help your child enhance their EF skills: 

Break Tasks Into Concrete Steps: 

Instead of “clean your room,” use a three‑step checklist. Instead of “do your project,” co‑create a timeline with mini‑deadlines.

Use “When–Then” And Time Chunking:

“When you work for 15 minutes, then we’ll take a 5‑minute movement break.” Short, predictable work blocks help kids who struggle with sustained attention.

Model Planning Out Loud:

Narrate your own planning and problem‑solving (“I have 20 minutes, so I’ll do X first…”) so kids can internalize that process.

Teach Emotional Regulation Alongside EF:

Many kids can’t access planning skills when they’re overwhelmed. Brief regulation strategies (movement, breathing, sensory tools) unlock executive function.

Find Support if You Need It

At some point, you might need some professional support. Speak with your child’s teacher, since they may offer insights into the academics that your child finds stressful, such as adapting when the class schedule changes. “Occupational therapists, psychologists, and executive function coaches can provide individualized strategies, school accommodations, and parent training so the environment matches the child’s brain, not just the average expectation,” says Armstrong. “Done well, interventions don’t just demand more effort from kids; they change the supports, routines, and expectations so executive function skills can grow over time.”

Executive function is an integral, ever-adapting part of your child’s life, which is why it’s important to understand how it works and identify any potential issues. Now, your child may be the type of person who’s perpetually late, but with some coaching — and encouragement — they might surprise you and not just hand in their writing assignment on time, but even the day before.
