Today’s question comes from a parent of a 6-year-old whose teacher raised concerns about possible ADHD during a parent–teacher conference. I love this question because it centers on supporting the whole child rather than immediately jumping to labels, diagnoses, checklists, or medications. Let’s walk through it together.

Listener Question
Hi Dr. B, my son is six and in first grade. His first grade teacher has indicated that she thinks he could potentially have ADHD. He’s not hyperactive nor disruptive, but he does daydream a lot and kind of loses focus, starts doodling on his pages. He’s also younger for his age — a late July birthday — and we didn’t pull him back. We don’t have a formal diagnosis yet but were hoping to implement dietary changes to help with his focus.
Wondering if you think omega supplements for kids are beneficial. He’s not one to eat salmon or much else besides chicken nuggets, so just looking for alternatives to get omega-3s into his diet. And we’re wondering what you think about supplements for a 6-year-old. Thanks.
Why Age Matters More Than We Often Realize
This comes up a lot, especially in early fall after those first parent–teacher conferences — and especially with younger kids in the grade.
There are tons of studies showing that younger children in a class are significantly more likely to be diagnosed with ADHD, simply because they’re being compared to kids who might be 6–12 months older.
To me, that’s entirely unfair.
If their birthday had been a little earlier — or if they’d been held back — they likely wouldn’t be on the receiving end of an ADHD label. This speaks to a gap between developmental expectations and classroom demands.
Not all six-year-olds are the same developmentally, even if they’re in the same grade.
What You’re Describing Is Extremely Common
A limited attention span in first grade is normal. Honestly, as a 40-year-old, I have a limited attention span too — and a six-year-old’s natural attention span is five to ten minutes for tasks that aren’t deeply interesting.
A little bit of daydreaming? Doodling? Especially if it’s not interfering?
That’s developmentally typical.
Part of being six is learning how to direct attention, redirect attention, and notice, Hey, I’m off task — what am I supposed to be doing? These are executive functioning skills that grow dramatically between ages 6 and 9.
Our goal is to support curiosity and learning without harming confidence.
If a child keeps hearing:
“Get back on task.”
“Why can’t you focus?”
“Stop doodling.”
They start thinking:
“I’m stupid.”
“Why do I always do this?”
“Other kids don’t get in trouble like this.”
We don’t want that. Not at six years old. Not ever.
The Three Big Areas to Check Before Even Thinking About ADHD
Before jumping to a diagnosis, I always look at three major foundations:
1. Sleep
Are they:
Falling asleep easily?
Sleeping soundly?
Waking refreshed?
Are there issues like:
Snoring
Sleep apnea
Chronic late nights
Screens before bed
A tired brain cannot sustain focus — especially during boring tasks (which, let’s be honest, a lot of first-grade work is).
2. Movement
Movement is huge.
Kids this age should be moving constantly. Movement improves dopamine release and dopamine sensitivity — both things that help with focus.
If a child is struggling in school, I ask:
Can they stand at their desk?
Can they use a standing desk?
Can you put a resistance band around the chair legs for foot bouncing?
These are incredible tools for increasing attention without medication and without constant correction.
3. Food and Blood Sugar
Most children eat more ultra-processed foods than ideal. We know these can increase inattention and hyperactivity in many kids.
Some children react to food dyes, too. Not all — but some.
You don’t need to go to zero. But if you notice a clear pattern (“red dye turns them into a tornado”), respect what you’re seeing.
Breakfast matters a lot:
High-protein + healthy fat = stable blood sugar
Cereal + carbs = crash + hunger + distractibility
Stable blood sugar equals stable focus.
Supplements: Iron, Magnesium, Omega-3s
Once sleep, movement, and nutrition are addressed, supplements can be incredibly helpful — and they often fill in biological gaps that make attention harder.
Here are the three I always consider:
1. Iron (Ferritin)
I like to test first.
Not just a finger poke for anemia, but a ferritin level.
Ferritin shows iron stores, which influence:
Dopamine synthesis
Dopamine transport
Executive functioning
A child can have normal hemoglobin but still low ferritin — and low ferritin can absolutely affect attention.
2. Magnesium
Many kids with ADHD symptoms have low magnesium.
Magnesium supports:
Calmness
Focus
Sleep
Nervous system regulation
You can check an RBC magnesium level, but many families supplement based on symptoms alone.
3. Omega-3 Fatty Acids
As this mom asked about — yes, omega-3s can help.
They’re important for:
Neurotransmitter synthesis
Neuron health
Reducing inattention
Reducing hyperactivity
And yes, they come in gummies.
Most six-year-olds aren’t loving smoked salmon.
My Vitamin Philosophy
If a child is doing well academically and behaviorally — no big concerns — they likely don’t need a multivitamin. Their development shows they’re getting enough biologically.
But if challenges are present, supplements can fill real gaps that are working against the behavior we want to see.
And Finally: Watch the Schedule and the Screens
Kids need:
Outdoor time
Downtime
Time to move
Time to reset
And with screens:
The litmus test is simple —
Can they turn it off without a battle?
If turning off the iPad is a meltdown every time, that means:
Too many screens → dysregulated nervous system → harder to focus → harder to behave → harder to sleep.
A Slow, Thoughtful, Whole-Child Approach
I love helping families with ADHD concerns because the typical approach is so rushed:
Symptoms
Checklists
Diagnosis
Medication
But before we even get close to those steps, there is so much we can do to support a child biologically, emotionally, and developmentally — especially at age six.
I hope this helps.
