For every parent who’s worried about their child’s weight or size, Kids Thrive at Every Size offers an approach to health that focuses on the whole child—not just the growth chart.

All children deserve a future free of health concerns and one full of self-esteem and wellbeing, no matter their size. Yet, given the rise in childhood obesity, there’s enormous pressure on parents to raise fit, thin kids – even if their kids aren’t designed to be that way. So, what does a healthy, fit child look like, and how can parents actually raise one, especially in a world of abundant food, busy lives, toxic diet culture, and societal pressures? Pediatric nutritionist Jill Castle offers parents a roadmap for navigating the ins and outs of raising children who are larger, smaller, or in-between. Drawn from science and experts in medicine, psychology, exercise, sleep, media, and nutrition, this book helps families establish healthy habits with a heightened awareness of the social issues, health concerns, and psychological impact of growing up in today’s culture, especially when larger or smaller. Kids Thrive at Every Size is a holistic, whole child approach to health—focusing on physical and emotional wellness—and empowers parents to create a positive culture of health and self-esteem in their kids, no matter their size.
