This study helps parents of kids who survived cancer learn how to prevent and reduce obesity in their children. Obesity means having too much body fat. This study has two groups: NOURISH-T+ and Brief NOURISH-T+. Both groups will learn online through video calls. The **NOURISH-T+** group has six weekly sessions, each 1-1.5 hours long, and two shorter sessions with the child. Parents will also talk to a dietitian for nutrition advice. The **Brief NOURISH-T+** group has one session, plus they receive helpful brochures. Kids aged 5-14 who have finished cancer treatment at least 6 months ago and are overweight can join. Parents must be 18 or older, the main meal preparer, and speak English or Spanish.
- **Length of Study:** Sessions last 6 weeks, with follow-ups at 2, 4, 8, and 10 months.
- **Visits Needed:** Online visits only, no in-person required.
- **Compensation:** Learn skills to improve your family's health.
