What is the standard weight for newborns?

Some women have a big belly during pregnancy, but the baby they give birth to is very small. At this time, the mother is more worried about the health of the child and wonders whether their weight is normal. There are also some premature babies and multiple births, and their weight is generally lighter. What is the standard weight for a normal newborn? Mothers must want to know. Let's take a look at the answers given by experts.

Weight is an important indicator reflecting the maturity and nutritional status of newborns. The lighter the weight, the poorer the intrauterine development and the more immature the baby is, and the greater the risk of illness and death. The birth weight of boys in my country is 3.21±0.37 kg and the birth weight of girls is 3.12±0.34 kg (according to the results of a nationwide epidemiological survey in nine cities in 1985). Weight gain during the neonatal period should be greater than 600 grams, and the weight at one month is generally 4.60~4.90 kilograms. Newborns who gain less than 600 grams at the age of one month should be classified as weak children. It is necessary to find out the cause with the help of a health care doctor and take targeted measures.

● Physiological weight loss: Newborns may experience physiological weight loss due to changes in the external environment after birth and low intake in the first few days after birth. The weight loss usually does not exceed 8% of the birth weight and the baby will recover in 7 to 10 days. After that comes the fastest period of weight gain in life, with daily weight gain reaching more than 50 grams.

● Low birth weight babies, normal weight babies, and macrosomia. Low birth weight babies refer to newborns with a birth weight of less than 2500 grams. Most premature babies born between 28 and less than 37 weeks of gestation belong to this category. Some full-term infants may also suffer from low birth weight due to developmental delay in the mother's womb. Normal weight babies refer to newborns with a birth weight of 2500 to 4000 grams. Usually, full-term babies born between 37 and 42 weeks of gestation fall into this category. Macrosomia refers to a newborn baby with a birth weight greater than 4000 grams. It is more common in pregnant mothers with diabetes or who overeat in the late stages of pregnancy.

Weighing newborns:

1. Take off all your clothes

2. The reading is accurate to 50 grams.

After reading the newborn weight standards introduced by the experts above, I believe all mothers have a general understanding. The weight of newborns is different. Some children are very heavy when they are born, but may become very small as they grow older. Therefore, for expectant mothers, as long as they are healthy and have adequate nutrition, their babies will generally not be very small when they are born.
