Question
What is the normal height for a 44-month-old baby boy?
Answer
The height of a 44-month-old baby boy can be estimated using the following formula: Height (centimeters) = Age × 7 + 70. If the baby has normal appetite, good immunity, and does not often catch a cold or have oral ulcers, and has dark hair, there is usually no need for detailed checks of trace elements. If any of these symptoms are present, a thorough examination is needed, and nutritional supplements may be selectively provided based on the situation.
