Question
A 5-year-old 2-month-old boy is only 103 cm tall, has a limited appetite, and has difficulty falling asleep at night. The parents are concerned about whether his height and weight are within the standard range.
Answer
According to the standards, the weight range for a 5-year-old boy is between 13.50 and 27.85 kilograms, with an average weight of 20.40 kilograms; the height range is between 98.7 and 124.7 centimeters, with an average height of 113.86 centimeters. For girls, the weight range is between 12.93 and 26.87 kilograms, with an average weight of 19.37 kilograms; the height range is between 97.8 and 123.4 centimeters, with an average height of 112.54 centimeters. After the age of 5, children’s growth rate slows down, and their monthly growth rate also slows. This is because children in this stage have basically reached their full potential, and their growth and development speed is relatively slower, and with increased physical activity, weight gain will no longer be rapid.
