How many pounds does a newborn baby gain in one month?

When a baby is born, it has excess fluid in its body that it loses within a few days, and it also passes black meconium. Most babies lose 10% of their birth weight within the first 5 days of life, and regain it within the next 5 days, so that within 10 days the baby can regain their birth weight. After regaining their birth weight, most babies grow very quickly, especially during the growth spurts between 7 to 10 days and 3 to 6 weeks. The average newborn gains 20 to 30 grams of weight per day, and will weigh 4 kilograms by the time he is one month old. During the first month, he gains 2.5 to 4 centimeters in length. Boys gain slightly more weight than girls and are also slightly longer than girls. The average head circumference of a newborn is 35 centimeters, which increases to 37.75 centimeters by the time he is one month old, with boys being slightly larger than girls. During the first month after birth, the baby gradually stretches out from the curled-up position that was formed in the womb at the end of pregnancy. He begins to stretch his upper and lower limbs and back from time to time, and his legs and feet may continue to rotate inward, giving him a bow-legged appearance, which usually corrects itself over the next 5 to 6 months.

How many centimeters does a newborn grow in one month

From birth to one year old, the baby's height generally grows 25cm; in the first 6 months, the average monthly growth is 2.5cm, a total of about 15cm; in the next 6 months, the average monthly growth is 1.5cm, a total of about 10cm. In the first three months after birth, the baby's weight increases by about 700-1000g per month, from March to June, the average monthly increase is about 600-800g, and from July to December, the average monthly increase is about 350g.

One month development standard for newborn babies:

Boy baby: height 48.7-61.2cm; weight 3.09-6.33kg; head circumference 33.3-40.7cm.

Baby girl: height 47.9-59.9cm; weight 2.98-6.05kg; head circumference 32.6-39.9cm.

There are individual differences between babies

Newborn baby weight gain standard

Newborns will experience temporary weight loss in the 2 to 3 days after birth due to the excretion of meconium and absorption of vernix caseosa, as well as water loss. In addition, their sucking ability is relatively weak at this time and they eat less milk. Some babies may even weigh less than when they were born, which is clinically called "physiological weight loss."

Newborns will also lose weight on the 3rd to 4th day after birth, which is about 6-9% lower than the birth weight. For example, if the birth weight is 3700 grams, it may decrease by about 222-333 grams in the 3rd to 4th day after birth. As the baby's milk intake increases, the body adapts and the weight will slowly increase. If the decline exceeds 10%, it is abnormal and the cause should be found to see if the feeding is correct and the milk supply is sufficient.

The baby's weight gain can also be used to measure whether the breast milk supply is sufficient. In the first week after birth, the weight of the newborn will decrease. As the baby grows, the weight will increase by about 115-200 grams per week in the first few weeks if the breast milk supply is sufficient. In the first 3 months, the weight can increase by 180-200 grams per week, 150-180 grams per week for 4-6 months, and 90-120 grams per week for 6-9 months.

Newborns can be weighed at 2, 4, 6, 9, and 12 months after birth; 1-3 years old can be weighed once every six months; 3-7 years old can be weighed once every twelve months. If the weight curve is parallel to the standard weight curve, it is normal.
