Doctor's answer (1)
Dr. Xie Zixing
A premature infant typically gains about 2 to 3 jin (1–1.5 kg) in weight per month, depending on feeding methods. With breastfeeding, a premature baby usually gains around 2 jin (1 kg) per month, as breast milk contains abundant high-quality proteins and various trace elements that support the growth and development of preterm infants. It also provides natural antibodies that enhance resistance. When formula feeding is chosen, a premature infant generally gains about 3 jin (1.5 kg) per month, which can also adequately meet their growth and developmental needs.
