Do You Have a Child Growing Up in a Larger Body?
Join Jill Castle, MS, RDN
for an 8-week Parent Group Program
If you’re like many parents, you worry about your child’s health – and their happiness. Especially if they’re growing up in a larger body.
Perhaps, you’re seeing habits that concern you. A body that’s growing bigger or faster. Or, maybe you’re noticing a change in self-esteem.
If your child…
- likes to eat too many sweets and treats or prefers carbs
- eats too fast
- sneaks snacks or eats in secret
- overeats at parties or never seems satisfied
- eats everything in sight
- gets emotional about food or you get emotional about your child’s reactions
- causes drama or distress at mealtime
…then watching your child head down an unhealthy path is likely causing worry, frustration, helplessness, and guilt.
Here’s the truth: You’re not a bad parent. And your kid is not a bad kid.
But you haven’t figured out how to create an environment that supports your child’s health and wellbeing…yet.
An environment that…
- models lifestyle habits and attitudes that support health and wellbeing
- uses proven, science-backed routines that promote good health
- cultivates positive body image, worthiness, and self-esteem
- celebrates food, eating, bodies, and health without shame or restrictive diets
- produces a child who is both healthy and happy no matter their size
I help parents create the home environment children need to grow up healthy, inside and out (without restrictive dieting or hurting their self-esteem).
The truth is, creating an environment that capitalizes on health and wellbeing now is a gift that keeps on giving. Because your child learns how to live healthfully as they grow up, rather than relearning and changing old habits as an adult.
Even more critical, if your child carries more body fat, preventing health conditions is paramount.
The good news is you can support your child through a “Whole Child Healthy” approach, promoting their health while simultaneously protecting their self-esteem.
That means no diets. No pressure. No shame.
Just an environment that makes healthy living easy…and enjoyable.
How will you do this exactly?
By joining my group parenting program, Raise a Child Who Thrives. In this 8 week program, I teach you how to tailor the environment at home using 8 key health behaviors all children need to grow up healthy and happy.
You’ll learn to cultivate structure, routines and a positive culture in your home around:
- food
- mealtime dynamics
- eating
- sleep
- movement
- screentime
- self-care
We cover family dynamics, the family culture, sleep, movement, food balance, feeding kids, eating behaviors, screen time, and how to support your child in the body they have… all of this without shame or harm.
If your child is…
- growing up with a larger body
- choosing (or eating) too many sweets, treats, or less-than-healthy foods
- overeating, sneaking, or eating due to boredom or emotions
- engaging in too much screen time
- resisting sleep routines
- skipping breakfast and snacking after school and all night
- fixating on food (what, when, how much…)
- showing signs of diminished self-esteem or body image
- dealing with out-of-whack lab values
- or anything else that concerns you about your child’s health and wellbeing…
I’d love to ease your worry and help you understand the many ways you can support your child’s health without harming their emotional wellbeing.
Here’s how this works…
- Raise a Child Who Thrives group parenting programs run several times throughout the year. Our next cohort will begin on July 8, 2026. Get on the waitlist here.
- We will meet on Zoom every Wednesday from 12 to 1 pm ET for 8 weeks. (A Zoom link will be provided to you and recordings of the sessions will be available for the duration of the program.)

I wrote Kids Thrive at Every Size to empower parents to implement healthful habits and raise healthy, happy kids — without shame or guilt.
I also wrote it for parents and caretakers of children who are in a larger-sized body, who may have a high weight, or who may be on a path to health concerns. I know the home environment has a powerful influence on children’s health and I want to help families optimizes that environment, so their kids can thrive at every size.
This experience isn’t about diets. Or forced exercise. My “Whole Child Healthy” approach nurtures health and wellbeing through lifestyle habits while being sensitive to the “danger zones” when kids have larger bodies.
You’ll get my tailored advice from 3 decades of expertise and experience as a pediatric dietitian who works with real life families. My goal is to help you establish a home environment that will promote your child’s health and wellbeing.
If this feels like a good next step for you, I’d love to have you join our next cohort!
After completing Jill’s program, I feel free! Free of the constant worry and guilt — I now have a focus and the tools to help my overweight child become healthier.
