How much should a four and a half month old baby weigh?
Answer
According to the baby weight estimation formula for the first 6 months, the baby’s weight should be approximately 9 jin and 6 liang, indicating a slightly overweight condition. Baby growth is rapid within the first 6 months, so there is no need to worry excessively. You can observe the baby’s weight changes and consult a hospital if you are concerned.
