You have a folder. Maybe it is a real folder, maybe it is a photo roll full of lab results and after-visit summaries. In it is every specialist you have seen, every test that came back normal, and every strategy somebody told you to try. And your child still isn't okay.
You've done everything right. You've shown up, you've pushed for answers, you've tried the strategies. And something is still being missed. You've been told he'll grow out of it. You've been told to give it time. But you are the one who lives with this child every single day, and you already know something doesn't add up.
Hear this clearly: there is no judgment in looking for more answers. Wanting a fuller explanation doesn't mean you distrust your pediatrician. It means you are paying attention.
What do parents ask me most about this?
Short answers first. The full reasoning is below.
Am I wrong to want more answers?
No, and there is no judgment in looking for them. Wanting a fuller explanation does not mean you distrust your pediatrician. It means the account you have does not yet explain your child.
My child's labs were normal. What does that actually mean?
That the number landed somewhere inside a range built from a lot of other children. It does not mean your child is doing well. I look at where a number sits inside the range, not only whether it squeaked in.
Should we pull dairy and gluten?
I do not do blanket eliminations, and there is no one-size-fits-all on that. If you suspect a true allergy, that belongs with an allergist, because allergy has a defined workup.
Why does the gut come first?
Because if the gut cannot handle whatever else is going on, you will get nowhere. The loud signs are easy, but the quiet ones fool people: eczema, picky eating that keeps narrowing, restless nights.
Where does testing fit?
Foundations first, testing second, anything targeted third and last. Never the other way around.
What pediatric functional medicine actually is
Functional medicine is a way of asking why. Regular pediatric care is very good at naming what is happening and managing it, and that matters. Functional medicine takes the same child and works backward. Why is this stomach hurting. Why won't this skin settle. Why is this kid wired at 10pm and impossible at 7am.
I am not a replacement for your pediatrician, your therapist or your specialists. I work in conjunction with them. I don't hand out diagnoses and I don't take them away. My job is the medical layer underneath the behavior and the symptoms. Testing, not guessing.
I'm also honest about limits. I don't have all the answers, and some children need something I don't offer. If that's your child, I'll say so and point you toward who I think can help.
Why normal labs are not the end of the story
Normal on a lab report means your child's number landed somewhere inside a range built from a lot of other children. It doesn't mean the number is good for your child. A ferritin that is technically normal can still be too low for a kid who kicks all night. A blood sugar that looks fine at 8am tells you nothing about what happened at 3pm.
So I read labs differently. I look at where a number sits inside the range, not only whether it squeaked in. And I read it next to what you're telling me about your child at home, which is information no lab will ever produce.
I start with the Foundational Five
Before any testing, and before anything from a bottle, I look at five things: sleep, airway, nutrition, hydration and movement. I call them the Foundational Five. If those five aren't in place, none of the rest of it matters much. That order is not negotiable in my practice.
Sleep
Sleep is where the body does its repair work, and it's also where the immune system does a lot of its learning. Researchers who reviewed this describe sleep and immune function as a two-way conversation: poor sleep changes immune signaling, and immune activation changes sleep.1 So a kid who is sick constantly and a kid who sleeps badly are often the same kid. There is more on this on my sleep page.
Airway
How your child breathes at night is its own subject and it gets missed constantly. Snoring, mouth breathing, night sweats, grinding, restless flopping, a head tipped way back on the pillow. None of that is normal. A child who can't breathe well at night doesn't act tired the way an adult does. He acts wired and oppositional at 10am.
Nutrition
Food is medicine, and it does most of the heavy lifting in my plans. When researchers pooled the studies on children and teens, better overall diet quality was associated with better mental health, and poorer diet quality with worse.2 That is a pattern, not a promise, but it is a strong enough pattern to build on.
Practically, that means protein and fat at breakfast instead of juice and cereal. It means looking hard at artificial dyes, hidden sugars, seed oils and heavily processed food. It means meal timing that doesn't leave a child running on empty by mid-afternoon.
Hydration
Under-drinking shows up as constipation, headaches, an afternoon crash and shorter tempers. Water in the morning, water in the backpack, water before screens. This one is free and most families see something within a week.
Movement
Daily movement, and ideally outside. Movement helps sleep, helps mood, helps the gut move and helps a nervous system settle. It only works if your child doesn't dread it, so pick what they'll actually do.
The gut usually comes first
If your gut can't handle whatever else is going on, you're going to get nowhere. That's why I work in phases and start with the gut. Your child's gut, immune system and brain are closely linked. When the gut is out of balance, the ripples show up everywhere else.
The research is going the same direction. What a child eats shapes the community of microbes in the gut, and that community influences the signals traveling to the brain.3 It isn't magic and it isn't a cure-all. It's plumbing and chemistry.
The loud signs are easy: stomach aches, constipation, diarrhea, bloating. The quiet ones fool people. Eczema. Picky eating that keeps narrowing. Mood swings. Restless nights. Trouble with toilet training long after you expected it to be done.
Skin is worth a paragraph of its own. You can see eczema and skin problems as almost a first symptom, because skin is the largest organ and it shows you right away. Allergy researchers describe eczema in early childhood as often the first step on a longer path that can include food allergy and asthma.4 So when a parent tells me about rough patches behind the knees, I don't file it under skin. I file it under whole child.
What I won't tell you to do
You have probably read that you should pull dairy and gluten. I don't do blanket eliminations. There is no one size fits all on that, and I tell families no. Cutting foods out of a child who is already a narrow eater can cost you more than it gains you, in nutrition and in dinner table peace.
If you suspect a true allergy, that belongs with an allergist. Cow's milk allergy in particular has a defined workup, and expert groups have written out how it should be diagnosed and managed rather than guessed at.5 Guessing is how kids end up on three years of a restricted diet they never needed.
Food sensitivity testing is a different tool, and I use it when the picture calls for it. It helps separate a true pattern from a coincidence. Testing here means fewer foods come out of the diet, not more.
Where testing fits
Foundations first. Testing second. Anything targeted third and last. Never the other way around. A test run on a child whose body hasn't slept in two years mostly tells me about exhaustion.
When testing does earn its place, what I order depends entirely on the child in front of me. It might be iron and ferritin. It might be a basic metabolic panel with a fasting glucose. It might be stool and gut microbiome testing, or organic acids testing when the picture calls for it. I don't order a fixed panel, because there isn't one. There is your child. And when a family's budget means choosing one test over another, I'll tell you honestly which one I'd choose first.
About supplements
A lot of functional medicine practices get a bad rap because they layer in twenty or thirty supplements at once for a kid. I don't work that way, and I understand why you'd be skeptical. Healthy skepticism is welcome here.
Food does the heavy lifting. Everything else is chosen for your child specifically, guided by what their testing actually showed, for as long as they need it and no longer. I never hand a family a supplement because of a headline or a parent group post.
What working together looks like
The first visit is a free Happy Kid consult. We check in and ask one question: are we a good match for each other. I'll tell you honestly whether I can help. If I think somebody else is a better fit for your child, I'll say that instead. You can read more about me and how I work if you want to know who you'd be talking to.
If we do go forward, we work in phases. Gut first. Once that's in good alignment, we move to the next phase. It is guided, not a protocol, and it flexes to your child and to your capacity as a parent. That part matters, because the plan relies on you too.
What I will never do is tell you this is just how it is. More often than not, that's not true.
