Functional & integrative medicine www.integrativepediatricsli.com

I am a certified pediatric nurse practitioner (CPNP) specializing in integrative and functional medicine, looking for root causes of illnesses and always thinking “outside the box.” I care for children and their families all over the country, treating the whole child, not just the symptoms. Our goal is always to provide exceptional health care while also educating and empowering parents so they can be their child’s leading advocate, and developing and delivering evidence-based treatment plans using the most cutting-edge research. I have treated Autism Spectrum Disorders, PANS/PANDAS, allergies, and mitochondrial and metabolic disorders, among many others.

Cold & flu season is here, but your child’s immune system is ready to rise to the occasion.

When it comes to preventing illness, strengthening the immune system is the best place to start. At Integrative Pediatrics, I guide families in supporting immunity from the inside out — through hydration, clean nutrition, balanced routines, and safe detoxification.

Simple, everyday shifts can make a big difference.

Let’s give your child the tools they need to thrive all season long.

💬
“We already did blood work — why do it again?”
That’s a question I hear from many parents. And honestly? It’s a smart one.

Here’s how I explain it:
You wouldn’t drive your car for years without checking the oil or wiper fluid. The same goes for our kids. Regular lab work helps us catch those invisible “check engine” lights before they become problems — so your child can feel their best and thrive in every way.

Preventive care is powerful. And sometimes, the smartest thing we can do as parents is to look deeper even when everything seems “fine.”

📲 Have questions about what labs your child might need? Call 631-314-8317. I’m happy to help!

💗 As we wrap up October, let’s continue to reflect on the importance of Breast Cancer Awareness Month. It’s a time to celebrate survivors, stand beside those still in the fight, and honor the memories of those we’ve lost. Your courage and strength remind us why awareness and early detection matter every single day.

Awareness is powerful, but prevention is where we can take action. ✅ Screenings like thermography save lives. ✅ Knowing your body matters. ✅ Lifestyle choices, from nutrition to reducing toxins, can help protect your health.

I believe in helping families take steps now to protect their health and their future. Prevention is one of the most important gifts we can give ourselves and the ones we love. 💞

Commit to spreading awareness and supporting survivors. Let's unite to raise hope, strength and awareness throughout this month 🩷

As October comes to a close, I want to take a moment to recognize something close to my heart: Down Syndrome Awareness Month. 💙💛

This month has been about celebrating the joy, strength, and unique gifts that individuals with Down Syndrome bring to the world, and that message continues long after October ends.

Brittany Schiavone, founder of Brittany's Baskets of Hope, is one of those individuals who brings joy, strength and hope to the world! Through her nonprofit, Brittany has delivered thousands of baskets to families across the US and Puerto Rico. As part of their mission, they create and deliver baskets to celebrate the arrival of babies with Down Syndrome, filled with information and guidance for parents, along with gifts of love and joy for the babies and their siblings. Brittany’s passion proves that every child’s possibilities are endless.

At Integrative Pediatrics, I believe every child has something special to offer. Let's celebrate every day with "joy that transcends differences, rises above challenges and gently reminds us that the world can be a brighter, more beautiful place when we share it with care." 🫶

🌿 Did you know that many standard allergy tests contain preservatives?

RAS tests and allergen injections often include ingredients that can actually alter your response — making results less reliable and sometimes triggering unnecessary reactions.

That’s why everything I use is preservative-free.
Clean, safe, and focused on getting clear answers.

If you or your child are dealing with allergy symptoms, let’s take a closer look — the right way.

🧠 Today is World PANS/PANDAS Awareness Day; a time to shed light on two often misunderstood pediatric conditions that can drastically affect a child’s mental and emotional health.

Sudden tics. Mood swings. OCD behaviors. Loss of appetite. Night terrors. Trouble focusing. These symptoms can appear overnight in kids with PANS or PANDAS, and too often, they’re dismissed or misdiagnosed.

❤️ You are not imagining things. You are not alone. If your child seems “off” and you can't explain why, there may be more going on beneath the surface.

🧠 Did you know high histamine levels can cause:
• Brain fog
• Fatigue
• Inability to focus
• ADHD-like symptoms

I see it all the time. Young kids are being put on medications like Ritalin, Concerta, and Abilify without anyone ever checking their histamine levels.

If we just tested instead of guessing, we might find that the issue isn’t behavioral. It’s biological.

Histamine can affect the brain, behavior, and energy. And for many kids, it’s the missing piece of the puzzle.

If your child is struggling in school, can’t focus, or seems “off,” let’s look deeper together.

🌱 “You wouldn’t plant a seed in contaminated soil and expect it to grow. The same goes for conception.”

I wish I could coach more women before conception, because there is so much we can do to support fertility and reduce the risk of miscarriage when we prepare the body early.

Toxins play a major role in infertility and pregnancy loss. But most women are never told that.

Your body deserves to be supported, cleansed, and nourished before that seed is planted so it has the best possible chance to grow and thrive 💛

If you're thinking about starting or expanding your family, let’s talk. There are steps we can take now to help you feel confident and supported on your journey.

🎤 “I test, I don’t guess.”

Whether I’m working with kids or adults, I want real answers. That’s why I run labs to check for:
🩸 vitamin and mineral deficiencies
🧬 toxins, infections, and allergies
💩 and gut health (your second brain!)

If your gut isn’t working properly, your body can’t absorb what it needs to function. That’s where deeper issues can begin.

Let’s stop guessing and start understanding.
