Around the age of 8, children's growth slows down compared to their early years. On average, an 8-year-old weighs approximately 57 lbs for boys and 57 lbs for girls based on CDC growth charts1. At this age, boys and girls might start showing more noticeable differences in weight and height, influenced by factors such as genetics and hormonal changes.
