Question
What should be the height and weight of a 3.5-year-old baby to be considered within the normal range?
Answer
For a 3-year-old child, the weight typically ranges from 12.6 to 16.1 kilograms, with a height of approximately 90.0 to 98.1 centimeters. Generally, at this age, the height is around 91.1 to 98.7 centimeters, and the weight is between 13.0 to 16.4 kilograms. For girls, the height is generally between 90.2 to 98.1 centimeters, and the weight is from 12.6 to 16.1 kilograms. However, due to seasonal and sleep patterns, there can be differences in a baby’s height and weight. In hot summers, with shorter sleep durations and reduced appetite, weight gain may be slower; in winter, with increased appetite and sufficient sleep, weight gain may be faster. As long as a 3-year-old’s height and weight are not significantly different from the normal indicators, maintaining adequate nutrition and sufficient sleep time is sufficient. Some children may develop later or grow slower due to genetic factors.
