The expectant mother is pregnant for 280 days, but the fetus does not grow at a constant speed during these 280 days. Every day during pregnancy, the fetus has different changes.

The growth rate of the fetus in the mother is not always constant, and the growth of the fetus is divided into fast growth period and slow growth period. Therefore, the nutrition supplemented at different growth stages is also different.

This requires pregnant women to understand and learn pregnancy knowledge, grasp the rapid development of the fetus, increase nutrition, and avoid giving birth to premature babies and low birth weight babies.

Recently, a family in the community has added a new baby, and the only worry is that the child is too light.

It is two pounds lighter than a normal newborn. Although I didn't eat less nutrition during pregnancy, I asked my pregnant mother at the wrong time, which just missed the fastest period of fetal development.

Although children can supplement nutrition and gain weight the day after tomorrow, congenital malnutrition and low weight always worry parents.

The reason for the low birth weight of newborns may be that pregnant women do not grasp the growth period of the fetus during pregnancy, which leads to insufficient nutritional supplement of the fetus and the final weight is lower than the normal standard.

Then let's take a look. When is the rapid growth period of the fetus and when is the slow growth period of the fetus?

Division of fetal growth period

The growth and development of the fetus is a continuous stage, but this stage is unbalanced and grows at a constant speed. During the 280 days of pregnancy, the state of the fetus is different every day, and pregnant mothers also need to supplement different nutrition. Generally speaking, the fetus is divided into the following two growth periods.

Slow growth period

The slow growth period is divided into two stages: the first stage is from pregnancy to the twelfth week of pregnancy. The second stage is pregnancy 13- 14 weeks.

The first stage of fetal growth is the slowest, but it is also the key period of organ formation.

At this time, the fetus only needs to absorb some nutrients in the mother's body, which is enough for its own growth and development, so the pregnant mother at this time does not need "big supplement".

It is only necessary to maintain a balanced nutritional intake, especially to eat some foods rich in folic acid such as nuts and vegetables to promote the development of the fetal brain.

In the second stage, most tissues and organs of the fetus have differentiated, and the whole growth can be maintained only by supplementing appropriate nutrition.

Rapid growth period

In the slow growth period, mothers only need a reasonable and balanced diet and supplement basic nutrition and vitamins.

But in the rapid growth period, expectant mothers must seize the critical period of fetal growth and development. The rapid growth period of the fetus is also divided into two stages: 15-28 weeks of pregnancy and 29-36 weeks of pregnancy.

During this period, the fetus grows very rapidly and needs to be supplemented with a lot of nutrition to maintain its growth and development. Pregnant mothers can eat more high-protein foods and properly supplement trace elements such as zinc, iron and calcium to promote the baby's growth.

How to increase the weight of newborns

We have learned about the two stages of fetal development, and their growth rates are different. If the pregnant mother does not grasp the rapid growth period of the fetus during pregnancy, the newborn will be underweight.

Expectant mothers should not be too impatient, they can gain weight through their baby's diet. Let's take a look at several key points to increase the weight of newborns.

1) breastfeeding

Breast milk can enhance the virus resistance of newborns and reduce the chance of getting sick. And it is not easy to cause baby's allergies, spitting milk and constipation.

For low-weight newborns, the frequency of breast-feeding can be increased, and pregnant women can drink more nutritious soup to restore their health and increase the nutrition of milk, so that the baby can supplement enough nutrition and promote growth and development.

Although the formula of milk powder is precise, some babies can't stand the lack of natural trace elements in breast milk. Therefore, if circumstances permit, Ma Bao should insist on breastfeeding, which is also conducive to Ma Bao's physical recovery.

2) Eat more and eat less

We often hear that we should eat more meals and less food, so we can also adopt the method of eating more meals and less food for light-weight babies. Eat more and eat less, that is, let the baby feed more milk several times a day, but don't feed too much every meal. While giving the baby enough energy, it will not let the baby hold back or spit milk.

3) Add complementary food

When the baby is lighter, Ma Bao can add some complementary foods in advance to increase the baby's weight appropriately. Complementary food generally starts from the fourth month of the newborn, not later than six months.

When the amount of breast milk is too small to satisfy the baby, Ma Bao can add complementary food according to the baby's condition. The requirement of adding complementary food must be pasty and easy to digest.

Don't add too many kinds of complementary foods at first, so as to avoid baby allergies and find allergens. So at the beginning, you can add a complementary food, preferably vegetarian, and feed it with specially sterilized baby tableware.

Pay attention to the child's state when feeding, and start to feed the baby less complementary food. If the baby is not allergic and has no resistance, you can try to feed more. When the baby is familiar with the taste of this food, one or two foods can be added to the complementary food.

4) Appropriate exercise

Newborns with low birth weight may be prone to illness. Ma Bao should not only work hard on feeding, but also let the baby have proper exercise.

When the sun is good, you can go outdoors to bask in the sun and enhance your baby's physique. The baby should exercise moderately, because the content of organic elements in the baby's bones is high, which easily leads to bone deformation, so Ma Bao should pay attention to let the baby exercise scientifically.

Ma Bao can learn simple and safe exercise methods, such as baby touching baby gymnastics, to help babies exercise. You can also massage your baby's stomach frequently to help him digest and increase his appetite. When exercising, it is best to avoid the baby spitting milk half an hour after feeding.

Baby's weight is an important indicator to reflect their own health, and Ma Bao must not ignore it. Not only should we know more about pregnancy prevention, but also avoid the situation that the baby is underweight.

If Ma Bao doesn't grasp the fastest development period of the fetus during pregnancy, don't worry too much. You can consult a doctor or adjust the baby's diet properly after delivery and feeding to promote the healthy growth of the baby's weight.

Every parent wants to have a healthy baby. As long as parents know more about parenting knowledge, relax their mentality and raise their children scientifically, they will certainly make their babies grow up healthily.
