Functional and integrative pediatric care for complex concerns across Florida, plus local newborn home visits and membership-based primary care.

Lumira Pediatrics is a pediatric practice led by Dr. Irissa Rosario, a physician double board-certified in general pediatrics and pediatric hospital medicine. We provide functional and integrative medicine consultations for children with complex, persistent, or interconnected concerns, including eczema, allergies, digestive symptoms, feeding difficulties, frequent illness, and more. Consultations are available by telemedicine throughout Florida and in person for families in Central Florida. Lumira Pediatrics also offers local in-home newborn visits, feeding and weight support, tongue-tie evaluation and release, newborn circumcision, and limited-enrollment primary care memberships. Our approach combines conventional pediatric medicine with thoughtful, evidence-informed care that looks at the whole child rather than treating each symptom in isolation. I do not contract with insurance. Visits are direct-pay, and I can provide a superbill for out-of-network benefits. Please avoid sharing private medical details via Facebook messages. For urgent concerns, call your child’s pediatrician or seek urgent/emergency care.

Let’s work through this together. Maybe you’ve had a work up and everything was normal. You have been referred to therapy, but things are still so hard. You wonder about if an OAT test, MitoSwab, FRAT test and others people mention could help you understand how to better understand your child. I’m here to listen to you and to guide you to understanding your child’s symptoms and how to help them.

A note on new enrollment 💛

Beginning November 1, new enrollment in my primary care membership will pause, and I’ll be moving to a waitlist. My ongoing primary care panel is nearing capacity, and I want to keep giving every family the time and attention they deserve.

If you have already met with me, your spot is secured. Nothing changes for you.

Please note the practice is currently only enrolling infants and babies due early 2027.

Please schedule a virtual meet and greet now if you’re expecting and want Lumira to be your baby’s pediatric home, link in my bio. ❤️

If you have a pediatrician, but want a visit or two at home, nothing has changed. I’ll still see your baby! 🥰

You have a child with symptoms that no one has figured out how to treat and you want a deep dive. I’ll get to the root of the issue and heal your child, I’m still taking consults and would be happy to help! 🤗

Lumira Pediatrics is a pediatric integrative practice. Dr. Rosario is a board-certified pediatrician that practices holistically. Instead of just prescribing a medication to treat a symptom or brushing off parental concerns as normal, she thinks outside of the box to look deeper. Her goal is to help families understand the triggers and the factors that keep the symptoms coming back.

Common complex concerns
- Eczema
- Rashes
- Frequent illness
- Frequent cough and wheezing
- ADHD
- Autism work up
- Tummy pain and bloating
- Constipation
- Infant colic and reflux
- Neuroimmune concerns
- Any so much more

Are you supplementing with Similac Sensitive? it may not be the best choice for most babies‘ gut health. Here’s why. 👇

It has almost all the lactose removed and replaced with corn syrup and sugar. But lactose is the main sugar in breast milk and the largest solid component. It’s what babies are designed to digest, and true trouble with lactose is rare in infants.

All US formulas meet FDA nutrition standards, so your baby will grow on any of them. But the ingredients used to get there aren’t equal when it comes to gut health. Your baby’s microbiome is built over the first 1,000 days, and the first 6 months are the most sensitive window.

What I look for in a formula:
✅ Lactose as the main carbohydrate
✅ Prebiotics

If your baby needs a specialty formula, that comes first. Don’t switch for gut health alone. There are other ways to support the microbiome, so talk with your pediatrician before making any changes. 💛

Save this for your next trip down the formula aisle.

If you’ve been told to “wait and see” while your child is still struggling with eczema, reflux, constipation, gut issues, ADHD, POTS, or other complex symptoms — you’re not alone.

At Lumira Pediatrics, we take a functional + integrative approach to pediatric care by looking at the full story: symptoms, history, environment, nutrition, labs, and the child as a whole.

The goal is a clearer path forward for your family.

The MAPS conference experience reminded me a lot of my first weeks as a new medical student, a new pediatric resident, and a new pediatric attending. At each stage of growth in my career, there’s a period of overwhelm and uncertainty. Imposter syndrome shows up.

I will always remember a conversation with my mother at the end of my first semester of medical school, when I thought it was too hard and didn’t think I could do it. She reminded me that if I wasn’t meant to do this, I wouldn’t have been chosen to do this.

I was a single mom when I went to medical school. I am the mother of two autistic children. I am the mother of twin NICU graduates. I am the mother of a transgender child. I am the wife of an immigrant. I am an entrepreneur who walked away from corporate medicine to practice the way I want to. I am the woman who learned how to be her true self — no longer afraid to be different, no longer afraid to ask questions and step outside the box that was created for me.

I am Dr. Irissa Rosario, MD, Founder of Lumira Pediatrics.

A new chapter. 🤍

This week I’m in Philadelphia at the MAPS conference, beginning my training toward becoming a MAPS Fellow through the Medical Academy of Pediatric Special Needs and expanding the care I can offer the families I serve.

I’ve always been drawn to the questions that don’t fit neatly into one box: neurodevelopment, inflammation, the gut-brain-immune connection, and the medical concerns that can sometimes be overlooked once a child has a diagnosis like autism.

As both a pediatrician and a mom of two children on the spectrum, this work is deeply personal. In many ways, it feels less like I chose this path and more like it kept finding me.

I feel incredibly blessed to be here, grateful for the opportunity to keep learning, and excited about what this next chapter will allow me to bring back to the children and families I serve. 💙

Once a child has an autism diagnosis, every symptom or behavior starts getting explained by the autism.

The fatigue. The constipation. The night waking. The new tremor. The skill that disappeared after an illness. It all gets folded into the diagnosis, and nobody looks any further.

But autistic kids get everything other kids get. Iron deficiency. Low B12. Thyroid problems. Celiac etc. And sometimes something metabolic or genetic that nobody ever went looking for.

When we find those things and treat them, your child feels better. That’s the whole point. A comfortable kid sleeps better, learns better, and gets more out of everything else you’re already doing for them.
