Happy Tummy Nutrition
Kristen Fustos, MS, RDN, CSP, LD, CLC
I’m a pediatric registered dietitian specializing in gut health. Through my practice, Happy Tummy Nutrition, I help babies and children with gut-related issues such as reflux, eczema, constipation, and food sensitivities using a functional, food-first approach. I combine evidence-based nutrition, a gut microbiome–supportive framework, and practical, family-friendly strategies to help kids feel their best, eat better, and thrive!
