“I want to make the evidence come alive, translating it into practical information families and professionals can use right away.”

As a writer who writes childhood nutrition and feeding articles, my learning curve has been wide and steep.

Early in my career as a childhood nutritionist, I wrote scientific research articles and textbook chapters.

Now, I translate the science into understandable tips and practical advice for parents and practitioners on my weekly blog, childhood nutrition articles, and in the books with which I have been involved.

My experiences as a childhood nutritionist and mom have shaped my vision about nutrition.

So much so, I partnered with a like-minded dietitian and wrote a comprehensive resource on childhood nutrition: Fearless Feeding: How to Raise Healthy Eaters from High Chair to High School.

Fearless Feeding breaks down nutrition and feeding for each stage of childhood, including infancy, toddlerhood, childhood and adolescence.

My book for young athletes is called Eat Like a Champion: Performance Nutrition for Your Young Athlete.

This book is for parents and coaches of young athletes aged 8 to 18. It showcases the latest science in sports nutrition for young athletes.

Not only do you get the science aimed at kids and teens, you get practical advice for how to put it into daily practice.

This book is a game changer for young athletes! 

I’ve also published my own books. The Smart Mom’s Guide to Starting Solids and Try New Food: Help New Eaters, Picky Eaters and Extreme Picky Eaters Taste, Eat and Like New Food.

Both are available on this website, as well as in print options on

I cover nutrition concepts and practical strategies.

I have also written for other sports-oriented websites, such as USA Swimming, US Rowing, the National Alliance for Youth Sports magazine, Sporting Kids, USA Field Hockey, and Golf magazine. For years, I wrote for Bundoo, a site for children ages 0-4 years,, and Wee Feed. 

You’ll also find me as the author of the nutrition chapter in ToughLOVE, a parenting anthology from Simon & Schuster.
