The biology beneath the behavior

Find what’s actually driving it

The meltdowns. The sleep. The food battles. The stomach aches. They may not be separate problems.

A 30-day guided group where we look underneath all of it together. You come away with a plan built for your child, and someone who knows what they’re looking at beside you the whole way.

Most families have a part of the day the whole house braces for.

You know roughly when it’s coming. You’ve moved things around it, planned around it, apologized for it. And somewhere along the way you started wondering whether a better parent would have solved this by now.

I want to tell you something it took me a long time to understand about my own son: you’re not looking at a behavior problem that happens to show up at the same time every day. You’re looking at a body that runs out of what it needs at the same time every day.

That’s a different problem. And it has a different answer.

Why the things you’ve tried didn’t hold

You’ve probably already tried something. A diet you read about. A supplement a group swore by. Cutting sugar. Cutting dyes. Maybe it did nothing. Maybe it worked for two weeks and then stopped, which is somehow worse.

These things usually don’t hold because of order. A child’s system has a sequence to it. What you steady first determines whether the next thing works. Take a food away before the foundation is set and you remove a small part of the load while the rest carries on. Add a probiotic to an unsettled gut and it can make things harder rather than easier. Change three things at once and it either helps or it doesn’t, but you’re left with no way of knowing which one to keep.

You weren’t wrong to try.
It was the right idea in the wrong order.

Where we start, and why there

We work on three things first: sleep, blood sugar and digestion. Not because those are the problem, but because in most of the children I see, they’re what’s producing the problem.

A child who slept badly, who’s running on a blood sugar crash, and who’s physically uncomfortable can’t regulate. Not because he won’t. Because the machinery isn’t available to him.

These three are also the fastest-moving things we have, and the safest to work on together. Steady them, and everything after works better.

Every week works on four things, not just food

This is the same foundation I use with families in my full program, shortened to what can be done well in a month.

Nutrition
What goes on the plate, when it goes there, and what it’s paired with
Supplements
Two or three, introduced one at a time, in the right form and dose
Lifestyle
Rhythm, timing, and when the hard things get asked of your child
Environment
Morning light, screens, movement, and the sensory load around them
1
Steady the fuel
Working toward calmer mornings and energy that holds, instead of a crash a couple of hours later.
2
Settle the evenings
Working toward easier afternoons, smoother transitions and a bedtime that isn’t a battle.
3
Make it the new normal
Making the changes stick through school days, busy weeks and real life, without it feeling like more work.
4
See what moved
Seeing what changed in your own notes, and knowing exactly what comes next for your child. Most parents are surprised.
The part most parents don’t expect

We start by identifying, not overhauling.

Right from week one, we identify two or three foods that may be contributing, and find better versions of the same foods your child already knows. Then we add protein, fat and fiber where the day needs it, so energy holds instead of crashing.

What we don’t do is clear out the pantry or hand you a list of forbidden foods. If your child eats six foods, I’m not going to ask you to make it five. Every change is chosen for your child, made one at a time, and you make it with me alongside you, not on your own.

What’s included

The Biochemical Balance Pattern Assessment
The questions that show me what’s driving it. I read every one myself.
Your personalized 30-day plan
Written for your child by hand, including what not to do yet, and why.
A live session with me every week
Wednesdays at 10am Pacific, 60 minutes. Bring your questions and I’ll answer them with your child in mind. Plus a short video and email each week telling you exactly what to focus on.
A Q&A channel
Ask between calls. Read what everyone else is asking. It’s often the thing you hadn’t thought to ask yet.
A one-page tracker
A few minutes a day, so you can see what you’d otherwise miss from inside it.
Every call recorded
Posted within a day if you can’t make it live. Send your question ahead and I’ll answer it.
30 days inside the Functional Nutrition community
My established community, with families a few weeks in and families a year in who remember what week two felt like. Plus the resource library: food lists, swaps, meal ideas, and the guides I’ve built over the years. Included for your 30 days, and you’re welcome to stay on afterwards.
ABOUT SUPPLEMENTS
Your plan includes a short protocol, usually two or three items, and around $100 with the discount code everyone in the group gets. Not included in the fee. Apart from the multivitamin they last well beyond the 30 days. I’ll tell you exactly what form and dose to look for so you can buy them anywhere.
New starts are limited, because I read every assessment myself and write every plan by hand.

What you’ll have on day 30

Not a guess, and not a stack of things to try. Here’s what you’ll actually walk away with.

A clear read on what’s driving the hardest parts of your child’s day
A plan built for your child, and the things I’ve told you to leave alone for now
Four weeks of data you collected yourself, so you can see what moved
A clear direction for what comes next, and why that’s the right order for your child
And the part that’s usually missing
Most parents aren’t short on information. They’re short on someone who knows what they’re looking at, standing beside them while they work it out. That’s the real thing you’re getting here: expert eyes on your child’s situation every week, and a group of families going through the same thing alongside you.
You won’t be figuring this out alone.
What we’re working toward is calmer digestion, easier sleep, and smoother going through the hardest parts of the day. Many families notice the mornings first. Every child is different, which is exactly why your plan is built for yours.
This is for you if
Your child struggles with behavior, focus, sleep, digestion or eating, diagnosis or not, and whether or not you’re still waiting on one.
You’ve tried things and watched them not hold.
You sense there’s a connection between what your child eats and how your child feels and acts, and you want someone to help you make sense of it.
This isn’t for you if
You’re looking for a single supplement to try on its own.
You need medical care for an acute condition. That belongs with your pediatrician, and I’ll tell you so.
You’re hoping for one quick fix rather than a clear place to start.

Nobody asked why my son was carrying all of this at once

I didn’t come to this work through a textbook. I came to it as a mom.

I took my son to four doctors and came home with four labels and four plans. The allergist handled the allergies. The gastroenterologist looked at his stomach. The pediatrician focused on his behavior. Nobody asked the question that kept me up at night: why was one child carrying all of this at once?

Then someone finally looked at the whole picture instead of one symptom at a time. It wasn’t five problems. It was one fire, burning in different rooms.

That afternoon redirected my career. I earned a master’s in human nutrition and functional medicine so I could turn clinical language into something a parent could actually use at the kitchen table at midnight.

Symptoms are clues, not the whole story. My job is to help you see what they’re pointing at and figure out where to start, not hand you another stack of disconnected ideas.

EDUCATION
Master’s in Human Nutrition and Functional Medicine
EXPERIENCE
Nearly 20 years working with families
If something isn’t working, tell me.
Early, not at the end. In a group this small I can almost always adjust something, like the order, the pace or one of the actions, and I’d far rather do that than have you quietly drift. If it turns out this isn’t the right fit for your family, I’d rather know that too, and we’ll talk about it honestly.

Start Monday

New families start every Monday. Join by Wednesday and your Day 1 is the following Monday. That gives me time to read your assessment and write your plan, and gives your supplements time to arrive. Live sessions are Wednesdays at 10am Pacific (1pm Eastern).

Questions parents ask me

Do I need a diagnosis?
No. Many families I work with are waiting on an evaluation, or have decided not to pursue one at all.
Will this replace my child’s therapies or medication?
No, and I wouldn’t want it to. This works alongside them. Please keep your pediatrician in the loop, especially about anything new you give your child.
My child only eats a few foods.
Then this was built for you. We start with the foods your child already eats, upgrading them and building on them rather than taking them away, and I’ll help you choose which changes to make first.
How much time will this take me each week?
A 60-minute call on Wednesday mornings, a few minutes a day on the tracker, and two or three small changes at home. It’s designed for a tired parent, not a spare afternoon.
What if I miss a call?
Calls are Wednesdays at 10am Pacific (1pm Eastern) and every one is recorded and posted within a day. You can also send your question in writing beforehand and I’ll answer it live.
What happens after the 30 days?
You’ll know what the next layer looks like for your child. You’re welcome to stay on in the community, and some families carry on working with me directly. There’s no obligation either way.

If the last few years have taught you to be careful with hope, I understand that better than most.

This is thirty days, a plan made for your child, and somebody who knows what they’re looking at, right beside you.
