Newborn birth weight standard

Ten months of pregnancy and one day of delivery establish the deep relationship between mother and child. A major problem faced by many babies after birth is the growth of the child. Many mothers attach great importance to the birth weight standard of newborns. Indeed, the quality of the complementary food recipe directly affects the normal development of the baby in the future. Of course, we must pay attention to nutritional balance, but we need to understand the specific birth weight standard of newborns? Many people do not have a clear understanding of this. Let us now learn about the birth weight standard for newborns.

Weight standard:

Indicator rules:

1. Height (length) refers to the sum of the lengths of the head, torso and lower limbs. The proportions of the three are different in different stages of the baby.

The younger you are, the larger the ratio of your head to your upper body. As you age, your lower body will grow faster than your upper body.

The average length of a baby at birth is about 50cm.

The height (length) grows fastest in the first year, with an average monthly increase of 2.5cm from 1-6 months, and an average monthly increase of 1.5cm from 7-12 months. At one year old, the baby is about 25cm taller than at birth, which is 1.5 times the height at birth.

In the second year after birth, the baby's height growth rate begins to slow down, only increasing by 10-12 cm throughout the year.

From the age of 2 until before puberty, the baby's height increases by an average of 6-7cm each year.

2-7 years old baby height calculation formula = age × 5 + 75cm

Tips

When measuring your baby's height (length), take off his shoes, hat and socks.

It is best to measure your height (length) in the morning so that the data obtained will be more accurate.

Small and uncooperative babies can be measured in a lying position. When measuring, make sure your knees are straight and someone has their head fixed with hands.

Boys of the same age have a slight advantage in height (length) over girls. Monoparticles, such as bottle, bath, ball, drink water.

2. The normal full-term baby weighs about 2.2kg-4.3kg at birth. [1]

In the first 3 months, the baby's weight gain is 0.18kg-0.2kg per week, 0.15kg-0.18kg per week at 4-6 months, 0.09kg-0.12kg per week at 6-9 months, and 0.06kg-0.09kg per week at 9-12 months.

Calculated by weight gain multiples, the baby's weight at 6 months is twice that at birth, about 3 times at 1 year old, about 4 times at 2 years old, and about 4.6 times at 3 years old.

In the second year after birth, the baby's weight increases by an average of 2.5kg-3kg.

After the age of 2, the average annual growth rate is about 2 kg until puberty.
