At 9 years old, children's bodies are still growing and adapting. The average weight for a 9-year-old typically ranges from 63 lbs for boys and 64 lbs for girls based on CDC growth charts1. Children at this age may experience variations in weight due to differences in metabolism and physical activity levels. Encouraging a supportive and non-judgmental environment can help children develop a healthy relationship with their bodies and promote a positive attitude towards their well-being.
