At what height and weight is normal for a one-year-old and two-month-old boy?

Patient's question:

No

Doctor's answer:

There are two methods to determine if a baby's weight is normal: age-weight and height-weight. The former is mainly based on the baby's actual age or month, using a calculation formula to determine the weight, or estimated according to the baby's growth rate, such as in the first 3 months after birth, the weight increases by 180-200 grams per week, from 3 to 6 months, it increases by 150-180 grams per week, and from 6 to 9 months, it increases by 90-120 grams per week.
