What if one of the most important things we could do for children’s learning happens before they ever open a book?
There were students I taught who came into my classroom tired every single day.
Sometimes they put their heads down before class had even really started. Others looked awake but struggled to sustain their attention through a lesson. Small frustrations became big ones. Reading felt harder. Writing felt harder. Sitting in a classroom and being expected to think, listen, remember, regulate your emotions, ignore distractions, follow directions, and produce work for hours at a time felt harder.
And then, very often, we treated those struggles as academic or behavioral problems.
We talked about missing assignments. Motivation. Attention. Executive functioning. Grades.
We rarely talked about sleep.
I spent more than a decade teaching high school students, and over the years I became increasingly interested in the conditions we were asking children to learn inside of.
Were they moving enough? Did they have time to think deeply? Were they interested in what they were learning? How much of their day was spent looking at screens? How much autonomy did they have?
Since becoming a parent, I’ve found myself asking a similar set of questions at home.
And one of the questions I’ve come back to again and again is remarkably basic:
Are they getting enough sleep?
How sleep affects learning, and why we overlook it
Modern parenting has become remarkably focused on optimization.
We think carefully about schools and curriculum. We sign children up for activities. We worry about whether they’re reading at the right level or getting enough enrichment. We buy educational toys, download learning apps, find tutors, research extracurriculars, and spend an enormous amount of energy trying to give our children opportunities.
Somewhere inside all of that effort, the foundations can become surprisingly easy to overlook.
Sleep doesn’t look productive.
There is nothing to show for it afterward. No completed worksheet. No new skill to post on the refrigerator. No measurable enrichment.
A sleeping child appears to be doing absolutely nothing.
Developmentally, of course, that isn’t what is happening at all.
Sleep is deeply connected to the very capacities we spend so much of childhood trying to develop: attention, memory, emotional regulation, learning, physical development and executive functioning.
How much sleep do kids need?
Probably more than you think. The American Academy of Sleep Medicine, in recommendations the American Academy of Pediatrics endorsed, puts it at 12 to 16 hours per 24 hours for babies 4 to 12 months, 11 to 14 hours for toddlers 1 to 2, and 10 to 13 hours for kids 3 to 5 (naps included for all three). Children 6 to 12 need 9 to 12 hours, and teenagers 13 to 18 need 8 to 10.
Those numbers aren’t a suggestion for well-rested families. The same statement links getting enough sleep on a regular basis to better attention, behavior, learning, memory and emotional regulation, and it links falling short to attention, behavior and learning problems (which, if you read the first part of this essay, will sound very familiar).
So if your eight-year-old needs to be up at 6:30 for the bus, the math says lights out somewhere between 6:30 and 9:30 the night before, which is worth holding up against what actually happens in your house on a school night.
Which makes me wonder whether we’ve sometimes gotten the order backward.
We spend so much time asking how to help children perform better during their waking hours without giving nearly enough attention to what makes those waking hours possible.
Homeschooling changed the way I think about mornings
One of the unexpected things I’ve appreciated most about homeschooling has very little to do with curriculum.
It’s the mornings.
Our children don’t generally need to be dragged out of deep sleep because a bus is coming or because everyone has to be out the door at a particular time. When our schedule allows for it, they can wake naturally.
Some mornings that happens early. Other mornings, especially after a particularly active day, a growth spurt, travel, illness, or simply being a human child whose body apparently needs more rest, someone sleeps later.
We adjust.
That flexibility has made me realize how unusual it is that sleep is expected to conform so neatly to our institutional schedules.
School has to begin at a certain time. Parents have to get to work. Commutes exist. Sports practices run late. Homework still needs to be finished. Families are navigating systems that weren’t necessarily designed around children’s sleep needs.
I don’t say that as an argument that everyone should homeschool. For many families, that isn’t desirable or possible. Plenty of children also thrive within traditional schools.
But homeschooling has given me a different vantage point from which to see how many parts of childhood we treat as fixed simply because our schedules require them to be.
Sleep is one of them.
Sometimes the environment deserves our attention, too
This is something I think about often after my years in education.
When a child struggles, adults naturally look at the child first.
How can we improve their focus or help them regulate?
How can we make them more organized?
How can we get them to complete their work?
And while those can be worthwhile questions, we need to start looking outward.
What is the environment asking of this child?
What basic needs might be competing with everything we’re asking them to do?
It’s part of a larger shift in how I think about childhood.
Before adding another intervention, another program, another activity or another strategy, I want to make sure we’ve paid attention to the foundations.
Sleep belongs very close to the beginning of that conversation.
Protecting sleep means thinking about the entire environment
Once I started thinking this way, I also became much more intentional about our children’s actual sleep environments.
We think about keeping bedrooms calm. We pay attention to screens around bedtime. We try to protect the hours available for sleep instead of treating bedtime as something that can continually be pushed later to accommodate everything else.
And I’ve become particular about what they’re sleeping on.
A mattress isn’t a particularly exciting parenting purchase. Kids aren’t going to unwrap one and lose their minds the way they might over a new bike.
But they’re going to spend thousands upon thousands of hours on it.
That’s why Happsy has become one of those brands we keep returning to in our family.
We’ve slept on Happsy mattresses for years, and they are the ONLY mattresses we currently use in our home. So when our youngest daughter recently moved into her own room in our new home and needed her first big-kid mattress, there was zero debate about what we were going to choose.
We went with Happsy again.
We’ve had Happsy mattresses in our house for six years, and I wrote about what that’s actually been like in my Happsy mattress review.
One of the things I appreciate about Happsy is the attention they’ve paid to materials. Their mattresses carry GOTS and GOLS organic certifications for the cotton, wool and latex, along with GREENGUARD Gold, MADE SAFE and EWG Verified, and they’re made without polyurethane foam, flame retardant chemicals, fiberglass or glues, which are exactly the materials I don’t particularly want my children spending every night surrounded by.
I’m generally skeptical of the way “wellness” gets marketed to parents. There is always another product we’re told we need to optimize our children.
I don’t believe a mattress magically creates a healthy child.
I do believe environment matters.
And when something is going to be in close contact with my child for roughly a third of every day, it makes sense to me to care about what it’s made from.
What to look for in a kid’s mattress
If you’re shopping for one right now, this is where I’d start, because a lot of mattresses get marketed as “natural” or “green” without much behind it. Look for third-party certifications you can actually check (GOTS for organic fabric and wool, GOLS for organic latex, GREENGUARD Gold for low chemical emissions). Look at what it’s made without, too: polyurethane foam, chemical flame retardants and fiberglass are the big ones parents tend to ask about. And think about how long your kid will actually sleep on it, because a twin bought at five might still be the bed they’re on at fifteen.
That’s the checklist that keeps bringing us back to Happsy, and I love knowing that the place my kids spend so many hours each night is one we’ve been intentional about too.
Maybe we need a broader definition of supporting learning
For years, I watched children struggle in classrooms and saw how quickly the conversation moved toward getting them to perform differently.
Now I find myself wondering how often we could begin somewhere earlier.
Children develop within environments. Their opportunities for movement and play matter. The technology competing for their attention matters. So do the quieter foundations we rarely associate with education at all.
Sleep is one of them.
I’ve become less interested in how much we can fit into a child’s day and more interested in whether we’re creating the conditions that allow them to thrive.
Sometimes supporting learning means finding the right curriculum.
Sometimes it means letting them sleep.
Whether your kids are in school or home with you all day, start here and I’ll point you to what fits your family.
