Patient's question:
My child weighed 8 pounds at birth and is now 110 days old, weighing 13 pounds. Is this normal? Also, I would like to ask if there is a certain period during which the heavier a child's birth weight, the heavier they should be later on? Or is it a sign of improper feeding?First follow-up question: I know a child who weighed 6 pounds at birth and is now also 13 pounds. Is this considered overweight?
Doctor's answer:
According to the formula, the weight for the first 6 months (in kilograms) is calculated as: birth weight + age in months × 0.7. Now the child is 110 days old, which is close to 4 months. Therefore, her weight should be 4 + 4 × 0.7 = 6.8 kilograms. That is equivalent to 13.6 jin. In other words, the child's current weight is within the normal range. The child's weight gain is not accelerating. That is to say, what you mentioned is "the heavier the birth weight, the heavier it should be later on." Since the child's weight is now within the normal range, it means her weight gain is normal. It suggests that your feeding is appropriate.
