Child Nutrition Guidance You Can Trust
Jill Castle, MS, RDN
Pediatric Dietitian | Author | Founder of The Nourished Child®
I’m Jill Castle, a pediatric registered dietitian with more than 35 years of experience helping children and families navigate nutrition, feeding, growth, and eating.
I’ve worked with children from infancy through adolescence in clinical care, private practice, education, and family nutrition. I’m also the author of six books about child nutrition and feeding and the host of The Nourished Child podcast.
My goal is simple: to translate nutrition science and decades of pediatric experience into practical guidance parents can actually use.

The Nourished Child Blueprint
Philosophy
Our Approach to Raising Healthy Eaters
Healthy eating isn’t about perfection. It’s about patterns over time.
At The Nourished Child®, we focus on:
- Positive feeding relationships
- Balanced nutrition (not restriction)
- Supporting growth in all body sizes
- Raising confident, self-regulated eaters
- Supporting development, movement, sleep, and emotional wellbeing
Because healthy kids are more than what they eat.
