If it has to do with kids and nutrition, I can help...

You Want to Raise a Healthy Child

And you want to feed him right.

But here’s the challenge: You’re not exactly sure how to do it.

What makes your job even more challenging? A difficult eater or a medical concern.

A Pediatric Nutritionist Can Help

You’re looking for advice because your toddler is picky, your baby is starting solid foods, or your child is not making healthy food choices.

Maybe your teen is gaining weight, losing (too much) weight, or is falling short of her athletic potential.

You’ve searched the internet, looking for help but nothing feels right.

I Help Parents Like You Raise a Healthy Eater

Because healthy eaters are more likely to turn into healthy adults.

It doesn’t matter if your kid is picky, an overeater, unhealthy eater, or living with a medical concern like food allergies, ADHD, or extra, unhealthy weight.

I’m Jill Castle, MS, RDN: A Registered Dietitian & Pediatric Nutritionist

I am a 27+ year veteran ing the field of pediatric nutrition.

I’ve had years of training and experience in this specialized field. I am knowledgeable and experienced with infants, toddlers, children and teens.

I’ve worked in a variety of settings.

I started as a clinical dietitian at Massachusetts General Hospital (I also did my dietetic internship training there), working with children from birth through adolescence who were hospitalized for various medical concerns such as cystic fibrosis, gastrointestinal challenges, diabetes, eating disorders and more.

After obtaining my Master’s degree in pediatric nutrition, I moved to Boston Children’s Hospital where I worked exclusively as a pediatric nutrition support dietitian using intravenous nutrition for kids undergoing bone marrow transplantation, gastro-intestinal diseases, cardiac surgery and intensive care.

Motherhood Made Me a Better Pediatric Nutritionist

Then, I had my own kids.

I took several years off of work to focus on raising them.

Boy, did I learn a lot about the day-to-day grind of cooking, snacks, meals, eating, feeding and all the stuff that goes into raising healthy kids who eat in a balanced way.

As a Pediatric Nutritionist, I Can Help

Raising healthy eaters isn’t easy. I know, because I have raised four of my own kids.

And, yes, I’ve had my own ups and downs.

C’mom, what parent hasn’t?!

I believe raising healthy kids is one of the hardest jobs of parenthood.

I talked about this in my TEDx talk.

Think about it: You have to deal with fussy eating, unhealthy weight, food allergies, sports nutrition, eating disorders, specialized diets for medical problems, and more, day in and day out.

Plus, you have to figure out how to get meals on the table, what to serve at snack-time, and the daily doubt about what to feed your kid.

I Can Show You How to Feed Your Child

During my experiences as a pediatric nutritionist, I developed a system and a strategy for feeding them good food in a loving way.

As a result of working with me, or using my nutrition classes and nutrition books, you will have a system and strategy for feeding your child in a balanced, nutritious way so you can live guilt-free and stress-free, while your child grows up healthy, inside and out.

Child nutrition is my passion. Helping parents like you is my purpose.

I believe your instincts are golden. You know that good food is important to the health of your child.

But it isn’t always easy to get it on the table, or get your child to eat it.

There’s more to the story, and you know it.

Bowl of fruit - Jill Castle, MS, RDN - Pediatric NutritionistYet, if you comb the Internet, flip the pages of any parenting magazine, or ask your neighbor, you’ll hear the same advice: try this food…or get rid of that food…

In other words, the message you get is:

Fix your child’s problem with food.

That doesn’t always work.

You’ll hear a very different message from me.

I know it takes more than changing the foods your child eats, or trying out some new, healthy recipe or fad diet to raise a healthy child.

Use a Modern Approach to Child Nutrition

Raising a healthy child requires a different approach. Good food isn’t enough.

Enter the blueprint of modern childhood nutrition, which includes:

  • Food and nutrients
  • Nurturing feeding practices
  • Childhood development

I feel strongly about what I call the “trifecta of child nutrition,” and it shows up in everything I do with, and for, parents like you.

I use this whole-child approach to educate, support and guide you to be the best food parent you can be. My systems and strategies are based on the research we have to date and my professional experience with real families like you.

Having a blueprint with a step-by-step system and strategy will help you feel more confident, at ease, less frustrated, on the right track, and fulfilled as you feed and raise your child.

[If you’re curious about what it takes, I’ve developed this checklist to show you.]

The Nourished Child® Path

I had to learn how to feed my kids in a way that honored their food preferences, while helping them expand their food repertoire.

I developed a food system and a nurturing feeding strategy to help kids tune in to their hunger and fullness signs so they could better manage their appetite.

I call it The Nourished Child® Path. It’s my method for assessing where you might need more support and help for your child.

I often do speaking engagements and workshops with professionals on this topic.

I learned so much more that I share with parents like you in my counseling, programs and books.

I’ve developed many practical, doable ways to shepherd your child through growth and development, eating and a healthy relationship with food.

Jill Castle, MS, RDN - Pediatric Nutritionist

I partnered with a like-minded colleague and wrote Fearless Feeding: How to Raise Healthy Eaters from High Chair to High School and hopped on the TEDx stage to propose a completely different (and modern) way of preventing childhood health problems.

Those nine years of being a stay-at-home mom were invaluable to my current practice style and my ability to see the big picture.

Let’s Use a Stress-Free, Guilt-Free Approach

In everything I do, my goal is to give you more insight and understanding about childhood nutrition and feeding kids.

Coupled with my extensive pediatric nutrition knowledge and experience, I’ve been able to help many kids and their families, no matter the challenge or concern.

Since 2008, I’ve had a private pediatric nutrition practice helping kids and their parents with weight and growth problems, picky eating, eating disorders, food allergies, sports nutrition for young athletes, gastrointestinal problems, and more.

Wait…What is a Pediatric Nutritionist?

A pediatric nutritionist is a nutrition professional (RD which stands for registered dietitian) who has been extensively trained in the science of nutrition, generally obtaining a B.S. from a university or college in nutrition.

The individual has completed extensive training with children which has qualified him or her to sit for a national registration exam. After passing, ongoing education and requirements must be completed every 5 years to stay knowledgeable, up-to-date and effective.

P.S.S.: 10 things you don’t know about Jill Castle, MS, RDN:

  1. I’m a mid-Western girl, born and raised in Indiana.
  2. I didn’t like broccoli until I was in my early 20’s. (Believe me, my parents offered it over and over.)
  3. I played basketball from 5th grade through my Junior year in high school. I wanted to be a cheerleader my senior year, so I gave up basketball. Big mistake. I didn’t make the cheerleading squad. (sad face)
  4. Mentally, and to this day, I’ve always considered myself an athlete. Physically, I was never more than a recreational, mediocre one. (But I still go for it!)
  5. I truly believe being a good parent is a lot of thoughtful work, and probably one of the hardest (and often, thankless) jobs on the planet. But, there is no other job that is quite as powerful or rewarding.
  6. I love a man who can cook (and who’s not afraid to do laundry and clean a bathroom…and a dirty diaper). Luckily, I snagged one.
  7. I’m a sucker for self-improvement and self-actualization. I read Atlas Shrugged by Ayn Rand when I was 18. I’m a big fan of Brene Brown and Oprah.You could say I’m a thinker. I like to figure out why people do what they do and how to be better.
  8. I’m very, very afraid of heights and speed. I generally avoid these situations. However, I zip-lined in Costa Rica and that was HUGE for me. Did I really do that?!
  9.  I do my best work very early in the morning, but I love a good, long sleep. So, basically, I fight with myself to get out of bed every morning. I love that snooze button!
  10. I have a super soft spot for children. I love, love, love them. Everything about them. They inspire me and make me laugh. I love to look at the world through their eyes.
