Why Is There a Standard for Baby Weight Gain?

Question

What is the standard for baby weight gain in pediatrics?

Answer

For babies between 1 to 6 months old, the weight calculation formula is the birth weight plus the age multiplied by 0.7. For instance, if the birth weight is 3 kilograms, according to this formula, a four-month-old baby should weigh around 5.8 kilograms. The height of a newborn at birth is typically 50 centimeters, and by one year, it reaches 75 centimeters. A four-month-old baby’s height does not have a fixed value, but the younger the baby, the faster the growth in height. Nutrition includes seven essential elements: protein, fat, carbohydrates, vitamins, water, fiber, and minerals; none can be missing. It is recommended that mothers consume more lean meats such as pork, chicken, and fish, and ideally drink a cup of prenatal milk powder in the morning and evening to increase the nutrition in breast milk. It is advisable to avoid consuming greasy and hard-to-digest foods like lard, pork feet, potatoes, taro, and soybeans.
