Patient's question:
My child weighed 8 pounds at birth and is now 110 days old, weighing 13 pounds. Is that normal? Also, I would like to ask if there is a certain period during which the heavier a child is at birth, 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 that 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. Currently, the child is 110 days old, which is close to 4 months, so her weight should be 4 + 4 × 0.7 = 6.8 kilograms, or 13.6 jin. This means the child's current weight is within the normal range.A child's weight gain does not increase at an accelerating rate, which is what you referred to as "the heavier the birth weight, the heavier the weight later on." Since the child's current weight is within the normal range, it indicates that her weight gain is normal, suggesting that your feeding is appropriate.
