Children's Nutritionist
Is Your Child Struggling With Energy, Digestion, or Development? I Help Families Decode What’s Really Going On.
As a children’s nutritionist in Sydney, I work with families who feel like something just isn’t right. Their child is constantly tired, irritable, or uncomfortable — struggling to keep up with school, sports, or everyday life. And despite trying different foods, supplements, or advice, nothing seems to stick. That’s because these challenges aren’t just behavioural or emotional — they’re often rooted in deeper nutritional imbalances.
I support children facing a wide range of issues: colic, reflux, constipation, and irritable bowel syndrome (IBS); carbohydrate intolerances like lactose, fructose, and sucrose malabsorption; and gut health concerns that affect mood, immunity, and absorption. I help manage food allergies (like milk and egg), coeliac disease, inflammatory bowel disease, and iron deficiency.Â
I work with fussy eaters, children who are underweight or failing to thrive, and those navigating overweight or obesity. I also provide tailored nutrition support for vegetarian diets, autism, ADHD, sports performance in young athletes, and children with special needs such as cerebral palsy or muscular dystrophy.
Finally, The Last Nutrition Plan You’ll Ever Need For Your Child
Children's Nutritionist: Children’s Initial Nutrition Consultation
This Is Not Your Standard Nutrition Consultation — It’s Personalised, Paediatric, and Purpose-Driven
This isn’t a generic nutrition appointment or a one-size-fits-all meal plan. As a children’s nutritionist, I offer a highly personalised consultation designed for families who are serious about supporting their child’s energy, digestion, growth, and overall wellbeing.
Together, we implement a clinically formulated, holistic, and sustainable nutrition and lifestyle strategy tailored to your child’s unique needs — whether they’re struggling with gut health, fussy eating, allergies, iron deficiency, ADHD, or growth concerns. I take the time to understand your child’s medical history, behavioural patterns, and daily routine, so every recommendation is practical, evidence-based, and built for long-term success.
This is about more than food — it’s about helping your child feel better, function better, and thrive in every area of life.
First 45 Minutes: Comprehensive Paediatric Nutrition & Wellbeing Assessment
In our first 60 minutes together, I’ll take a deep clinical dive into your child’s nutrition, growth patterns, and overall wellbeing. This includes a full analysis of their macro- and micronutrient intake, daily activity levels, sleep quality, and lifestyle habits. I’ll also explore behavioural, emotional, and environmental stressors that may be impacting their energy, digestion, mood, and development.
Whether your child is dealing with fatigue, gut issues, fussy eating, or growth concerns, this session is designed to uncover the root causes — not just manage symptoms. Together, we’ll set clear short- and long-term goals tailored to your child’s age, medical history, and unique nutritional needs. You’ll walk away with clarity on why previous diets, supplements, or advice may have fallen short — and a clear roadmap for what needs to change.
Final 15 Minutes: Your Child’s Personalised Nutrition Blueprint
To close the session, I’ll deliver your child’s personalised nutrition blueprint — a clinically formulated, holistic, and sustainable plan designed to support energy, digestion, growth, and emotional wellbeing. This includes tailored recommendations around food choices, nutrient timing, lifestyle adjustments, and sleep strategies that align with your child’s developmental stage and health goals.
As a children’s nutritionist, I don’t just offer advice — I build strategic, evidence-based plans that empower families to take control of their child’s health. This blueprint isn’t just about eating better — it’s about helping your child feel better, function better, and thrive in every area of life.

Children's Nutritionist: My Key Areas of Expertise
Irritable Infants (Colic & Reflux): Infant colic and reflux can be incredibly distressing — not just for babies, but for parents who feel helpless watching their child in discomfort. I offer compassionate, evidence-based support to help families navigate these early challenges with confidence. Through gentle dietary adjustments, feeding techniques, and a deep understanding of infant physiology, I help reduce symptoms and improve feeding outcomes. My goal is to bring calm back to your household and comfort to your baby.
Irritable Bowel Syndrome (IBS) & Low FODMAP Diet: When a child is dealing with IBS, every meal can feel like a gamble. I specialise in paediatric IBS management using the clinically proven Low FODMAP Diet — tailored specifically for growing bodies. I guide families through the process step-by-step, ensuring nutritional adequacy while reducing bloating, pain, and unpredictable bowel habits. With the right strategy, your child can enjoy food again without fear or discomfort.
Gut Health: Gut health is the cornerstone of paediatric wellbeing. From nutrient absorption and immunity to mood and behaviour, a balanced gut microbiome plays a critical role in how children grow and thrive. I help families nurture digestive health through targeted nutrition, lifestyle adjustments, and gut-friendly foods that support resilience from the inside out. Whether your child struggles with constipation, frequent illness, or poor appetite, I’ll help restore balance and vitality through the gut.
Carbohydrate Intolerances / Malabsorption (Lactose, Fructose, Sucrose): Children with carbohydrate intolerances need careful dietary management to avoid discomfort and support proper nutrient absorption. As a children’s nutritionist, I work closely with families to navigate these restrictions while maintaining balanced nutrition. By identifying suitable carbohydrate alternatives and implementing practical meal planning strategies, I help children thrive despite their dietary limitations.
Allergies (e.g. Milk and Egg): Food allergies can significantly impact a child’s diet and overall wellbeing. I provide families with clear, actionable guidance to manage these allergies safely and confidently. From allergen avoidance to nutritional substitutions, I ensure children receive the nutrients they need while enjoying a varied and satisfying diet—without fear of adverse reactions.
Fussy Eating: Picky eating can turn mealtimes into a daily struggle. I help families transform these moments into opportunities for growth and connection. By introducing new foods gradually, involving children in meal preparation, and creating a supportive eating environment, I guide families toward overcoming fussy eating habits and building a healthy, lifelong relationship with food.
Iron Deficiency: Iron deficiency can have profound implications for a child’s growth and development. As a children’s nutritionist, I design iron-rich meal plans and offer supplementation guidance to address deficiency and promote optimal health. By incorporating iron-rich foods into a child’s diet and optimising absorption through strategic dietary pairings, I help families ensure their children receive the nutrients they need for vibrant energy, focus, and growth.
Constipation: Constipation is a common issue in children, often with multiple underlying causes. As a children’s nutritionist, I provide tailored dietary and lifestyle recommendations to relieve constipation and support regular bowel movements. Through hydration strategies, fibre-rich foods, and gentle lifestyle modifications, I empower families to address constipation effectively and restore digestive comfort.
Coeliac Disease: Children with Coeliac Disease require strict adherence to a gluten-free diet to prevent symptoms and long-term complications. As a children’s nutritionist, I offer comprehensive support—from gluten-free food choices and label reading to meal planning and nutritional adequacy. I equip families with practical tools and confidence so their child can enjoy a varied, nourishing diet while safely avoiding gluten.
Inflammatory Bowel Disease: Managing Inflammatory Bowel Disease (IBD) in children requires a multidisciplinary approach, and I’m proud to be a trusted part of that care team. As a children’s nutritionist, I collaborate with healthcare providers and offer specialised nutrition plans to help manage symptoms, support gut healing, and optimise nutritional status. Through personalised dietary recommendations and ongoing support, I empower families to navigate the complexities of living with a chronic digestive condition.
Underweight / Failure to Thrive: Children who are underweight or experiencing failure to thrive need targeted nutritional support to promote healthy weight gain and development. As a children’s nutritionist, I address underlying deficiencies and design calorie-dense, nutrient-rich meal plans that support growth and vitality. With regular monitoring and compassionate guidance, I help families nurture their child’s health and build a strong foundation for lifelong wellbeing.
Overweight and Obesity: Childhood obesity is a complex issue that requires a thoughtful, evidence-based approach. As a children’s nutritionist, I support families in making sustainable changes through dietary adjustments, lifestyle strategies, and behaviour-focused guidance. My goal is to help children achieve and maintain a healthy weight—not through restriction, but through balance, movement, and positive habits that last a lifetime.
Vegetarian Diets: Vegetarian diets can be incredibly nourishing when thoughtfully planned. As a children’s nutritionist, I help families ensure their child’s vegetarian diet meets all essential nutritional needs. By focusing on plant-based proteins, iron-rich foods, and nutrient-dense alternatives, I create balanced meal plans that support optimal growth, development, and long-term wellbeing.
Autism / ADHD: Children with autism or ADHD often have unique nutritional needs, sensitivities, and behavioural patterns around food. As a children’s nutritionist, I offer personalised guidance to support their health and development. By addressing dietary triggers, optimising nutrient intake, and promoting balanced nutrition, I help children with autism or ADHD thrive—physically, emotionally, and cognitively.
Sports Nutrition for Children and Adolescents: Young athletes need more than just energy—they need strategic nutrition to fuel performance, support recovery, and protect long-term health. As a children’s nutritionist, I design sports-specific nutrition plans tailored to each child’s training load, goals, and growth stage. From hydration strategies to nutrient timing, I empower young athletes to perform at their best and build resilience from the inside out.
Special Needs Children (e.g. Cerebral Palsy, Muscular Dystrophy): Children with special needs often face unique dietary challenges that require thoughtful, individualised support. As a children’s nutritionist, I provide tailored nutrition plans that address deficiencies, support growth, and accommodate physical or behavioural limitations. My goal is to help families feel confident in nourishing their child’s health—no matter how complex the journey.
