Symptoms of a baby's tummy being pressed

In our opinion, babies are a vulnerable group because their defense capabilities against any external attacks are very weak. It can even be said that babies can only use crying to attract the attention of adults so that adults can help solve the problem. The baby's body tissues are not fully developed, and their bones and muscle tissues are very soft. So what symptoms will occur if the baby's stomach is accidentally pressed?

First observe whether the baby has any abnormal reaction. If the baby does not cry constantly or has a painful expression, it should not be a big deal. Because babies are very sensitive, they will cry to express their discomfort if they feel a little uncomfortable.

Infants are children under 1 year old. Babies grow and develop particularly rapidly at this stage, which is the most rapid growth and development stage in a person's life. Their weight is approximately 9,000 to 10,000 grams.

Babies born at full term already have good sucking and swallowing functions, and have thick fat pads on their cheeks that help with sucking activities, but premature babies have poorer abilities. Sucking is a complex natural reflex. Serious illness can affect this reflex, making sucking weak and powerless.

① The body weight can reach three times that at birth, which is about 9,000 to 10,000 grams.

② The height is about 50 cm at birth, and generally increases by 3 to 3.5 cm per month. It increases by 10 to 12 cm at 4 months, and can reach about 1.5 times the height at birth at 1 year old.

③The head circumference is about 34 cm at birth, increases by 8 to 10 cm in the first six months, and 2 to 4 cm in the second six months, reaching an average of 46 cm at one year old. The growth rate slows down afterwards, reaching about 56 to 58 cm in adults.

④ The chest circumference is 1 to 2 cm smaller than the head circumference at birth. By the end of 4 months, the chest circumference is basically the same as the head circumference.

⑤ The baby's brain is still in a period of rapid development for a period of time after birth, and the number of brain nerve cells continues to increase. It needs sufficient, balanced and reasonable support of nutrients (especially high-quality protein), so the demand for calories, protein and other nutrients is particularly strong.

The stomach capacity of a newborn is about 30 to 60 ml, which increases with age, to 90 to 150 ml at 1 to 3 months, and 250 to 300 ml at 1 year old. Due to the small stomach capacity of newborns, newborns should be fed in small amounts and multiple times, and the number of feedings should be more than that of older children. The baby's stomach is in a horizontal position, which changes to a vertical position when walking begins. The gastric smooth muscle is not yet fully developed, making it easy for the stomach to expand when filled with liquid food. Due to the low tension of the cardia muscle, the well-developed pyloric sphincter, and poor autonomic nervous regulation, pyloric spasm and vomiting are easily caused.
