Is 9 stones good for a very tall 12 year old girl?

A weight of 9 stones (approximately 126 pounds or 57 kg) can be considered healthy for a very tall 12-year-old girl, but it ultimately depends on her height, body composition, and overall health. It's important to consider growth patterns and individual differences, as each child develops at their own pace. Consulting with a healthcare professional or pediatrician can provide tailored guidance and ensure she is within a healthy weight range for her height.
