How big is a baby's stomach?

Sometimes babies spit up milk, sometimes because of air mixed in, and sometimes because the baby's stomach capacity is limited. If they are fed too much milk, it will cause milk reflux. Children do not have the ability to express themselves, and it is often difficult for parents to tell whether they have eaten enough, which is related to the children's health. So, how big is a baby's stomach? Let's take a look below.

Before feeding a newborn, it is necessary for young parents to understand the characteristics and capacity of the baby's stomach. The stomach is located on the left side of the abdomen, unlike the vertical adult stomach. The baby's stomach is in a horizontal position until the child begins to walk, at which point the position of the stomach gradually changes to a vertical position. The upper opening of the stomach is the part connected to the esophagus, which is medically called the cardia. The lower opening of the stomach is the part connected to the duodenum, called the pylorus. The gastric muscle layer of infants is poorly developed. An empty stomach shrinks, and taking in liquid food tends to cause the stomach to expand. Because the cardia is wide, the muscles there (medically called sphincters) are not fully developed and the closing effect is not strong enough; especially after swallowing too much air, milk regurgitation is prone to occur. The muscles at the pylorus are well developed, but due to the immaturity of the infant's neural regulation function, pyloric spasm and vomiting can often occur.

Young parents should give their children an appropriate amount of food according to their stomach capacity to avoid unnecessary regurgitation of milk or even vomiting, thereby ensuring the baby's nutrition and allowing the baby to grow more healthily.

A newborn (one day old) is 5-7, about the size of a marble. A few teaspoons of colostrum is just the right amount for your baby's first few meals.

3 days 22-30, equivalent to the size of a large glass ball. Small, frequent feedings ensure your baby gets the amount of breast milk he or she needs.

7 days 44-59, equivalent to the size of a ping-pong ball. Continued frequent feedings are best for the baby's appetite and for stimulating the mother's lactation.
