Question
The anterior fontanelle of a newborn is approximately 1.5cm×1.5cm to 2cm×2cm in size at birth and slightly increases in size over time. What are the weight growth standards for newborns?
Answer
Newborns may experience a temporary weight loss within the first week after birth, known as physiological weight loss. This usually reaches its lowest point around 3-4 days after birth and then gradually recovers. By 7-10 days after birth, the newborn’s weight should return to the birth weight. If the weight loss exceeds 10%, or if the weight has not recovered within 10 days after birth, it may be a pathological condition, and the cause needs to be analyzed, such as improper feeding after birth, factors affecting intrauterine development, or diseases in the newborn. In summary, newborns should gain 1-1.5 kilograms in the first month after birth.
