Question
How tall and heavy should a 3.5-year-old baby be considered normal?
Answer
The weight of a 3-year-old baby should be between 12.6-16.1kg, with a height of 90.0-98.1cm. However, a baby’s height and weight may vary slightly due to seasons and sleep duration. In summer, due to shorter sleep hours and reduced appetite, weight gain may be slower; while in winter, with better appetite and more abundant sleep, weight gain may be faster. As long as the baby’s height and weight are not significantly different from the normal range, and they maintain adequate nutrition and sufficient sleep, this is acceptable. However, due to genetic factors, some children may grow slower than others.
