What is the stomach capacity of a newborn baby?

The stomach of a newborn baby is very different from that of an adult, so we must be extra careful when feeding. If breast milk is not sufficient, it is best to feed the baby with artificial infant formula as soon as possible to ensure the baby's nutritional supply. When feeding a newborn, pay attention to the quantity and timing, and do not let the child eat one meal and go hungry the next. The stomach capacity of a newborn changes day by day. Here we will introduce the stomach capacity of a newborn.

In China, a newborn is defined as a baby from birth to one month old (30 days old). The neonatal period is a transition period from the fetal period when the child depends on the mother to the independent life of the child. Knowing the stomach capacity of a newborn can help you know the amount of milk you feed each time, and can also indirectly tell whether the baby is full or has been overfed. The stomach capacity of a newborn is about 20 to 45 ml, with an average of 30 ml. It increases significantly after the second week after birth. There is also increasing variability in intake among infants. The stomach capacity of premature babies is smaller than that of full-term babies, and the lower the weight, the smaller the stomach capacity. For example, if the birth weight is 2000 grams (4 jin), the stomach capacity is 10 to 25 ml, with an average of 15 ml; if the birth weight is 1500 grams, the stomach capacity is only 6 to 14 ml, with an average of 9 ml.

A one-day-old baby's stomach capacity is about 5 to 7 ml, or the size of a marble. Interestingly, the researchers found that the stomachs of one-day-old newborns do not stretch to accommodate more. Because the newborn's stomach lining remains tight, excess breast milk will be spit out. The amount of colostrum is just what your baby needs for the first few meals.

Through the above introduction, I believe everyone has a certain understanding of the stomach capacity of newborns. The stomach of a newborn is very delicate, so don't feed too much when feeding, otherwise it will easily cause indigestion in the child. Also, pay attention to read the instructions carefully when purchasing milk powder. Be sure to buy milk powder for newborns, otherwise it will be difficult for the child to digest after eating it, and the nutrition will not be supplemented.
