If you learn to talk to your baby, he will try different voices to answer you.

Human appearance and growth and development: at the end of the fourth month, close the rear chimney door; The head still looks big, because it grows faster than other parts of the human body, which is normal; His body can keep up quickly. At this stage, the baby's growth rate is slightly slower than that of the first three months.

The resting weight of the male baby is 4.7-8.5 kg and the body length is 58.3-69. 1cm.

The resting weight of the baby girl is 4.5-7.7Kg, and the body length is 56.9-67. 1cm.

Exercise: This month, when it is supported by elbows, it can stick out its head and breasts. This is a key training, so that he can be free to look around according to his own intentions. You can find that the child bends and straightens his legs independently, but it actually seems to stand up by himself (except for maintaining balance). Then he will try to bend his knees and realize that he can jump. Prone can look up 90 degrees; Keep your head steady when holding vertically; You can stand under your arm for a while; With the help of parents, the baby will change from supine position to prone position. You can hold your clothes, pants and a small quilt tightly; Shake your eyes and stare at the bell; Hand-eye coordination posture has just begun to emerge; When you lie flat, you will look up and see his feet. When you lie down, you will straighten your legs and gently stretch your hips. You can't sit still by yourself yet. I am very interested in the objects around the single bed, so I must grasp and touch them.

Development of cognitive ability of 4-month-old children

Vision: At this time, he will be able to track all the objects of fitness exercise in front of him. In addition, the coordination of eyes can also make his vision worse when he tracks the approach and end of his object. Flexible vision, can move from one block to another; Head-eye coordination is good, his eyes move left and right with the moving object 180 degrees, and he can follow the object. If the ball slips from his hand and falls to the ground, he will look for it with his eyes.

English Listening and Phonetic Pronunciation: Children at this stage develop rapidly in language growth and emotional communication. When you are happy, you will laugh loudly and laugh like a silver bell. When many people talk to him, he grunts with joy, as if talking to you. I am very interested in my own noise, and I will pronounce some monosyllabic sounds and repeat them constantly. Can make a loud cry or make a nice sound. The eyah tone is lengthened.

The growth and development of emotion and social media: It is not easy for a child to be very friendly to everyone. Of course, he loves his parents most. By the fourth month, he will like other children. If he has brothers and sisters, you will be happy to see him when they talk to him. If he hears children's voices in the street or on TV, he will turn around and look for them. As the child grows up, his love for the child will also increase. In contrast, he always looks at passers-by curiously or smiles. It can be seen that he has just begun to identify people in daily life. There is no doubt that he is very dependent on the people closest to him. He will learn to express his happiness by shaking his head and other gestures; At first, there was a fear or unpleasant mentality. In bed, I went to play by myself. Suddenly, the baby's posture slowed down, and his eyes stopped looking around, just staring at an area. After a while, everything returned to normal. What the baby wants to express is that I was joking happily, but I suddenly remembered something while playing. I paused, couldn't think clearly, so I played. Sit in front of the bathroom mirror opposite the door with the goods, let the goods face the bathroom mirror, and then knock on the laminated glass to attract the goods' attention to their image in the mirror. He can firmly stare at his back, smile at himself in the mirror and "talk" to him.

How to nurse the development of a 4-month-old child

1, Abdominal distension: When the abdomen swells, the baby's abdominal cavity will appear very obvious, especially when the baby is pregnant, the abdominal cavity will appear very relaxed. Massage can be used to relieve the baby's bloating.

2, rotavirus: the symptoms of rotavirus diarrhea are high fever, nausea and vomiting, abdominal pain, watery stool without blood. Diarrhea is milky white millet soup or light green egg fancy watery stool, which has a bad smell and does not contain blood and mucus. When the baby has this disease, he should be sent to the hospital for examination immediately.

3, food allergies: skin allergies are the most common situation in the whole complementary food addition process. Diarrhea and nausea and vomiting are also common symptoms when adding complementary food. I found that my baby has a rash or severe diarrhea, so I have to go to the hospital for examination.

4, drooling: the baby just started from 3-4 months, saliva metabolism increased. At the beginning, you can wipe his saliva immediately, and don't let him become a dirty baby.

5.

Generally speaking, it is best to cooperate with soft and safe baby moisturizer and touch the baby after taking a bath to nourish the skin and lock in moisture. After the baby takes a shower, it releases a refreshing fragrance, which allows you to have closer contact with the baby in the intimate years, so it is more suitable for the baby to touch. The baby's touch delay time can be maintained at 10 to 15 minutes, not more than 20 minutes at most, otherwise the baby will get bored.

6, vaccination: the baby must eat the third polio sugar pill this month, but also the second shot of DTP, don't forget.

The development process of 4-month-old children

Is it because you temporarily forgot the whole process of long and painful delivery that you quickly experienced personally that you studied medicine to cut off the fetal umbilical cord for your baby and solve it safely, hold him (her) on your naked and warm chest and kiss your skin? Does that strange feeling give you unforgettable feelings in your life: happiness, surprise, cherish, dreamlike and other emotions are intertwined, and you are a little unfamiliar and at a loss. The feeling of being fucked by your mother is becoming more and more real, because the baby who is deeply in love with your brother is in front of you, in your arms and close at hand.

Make persistent efforts in 2 weeks and integrate into this new natural environment. For him, the world is much noisier and brighter than his mother's palace, and he is not used to it. But you can find that the baby is developing every day, and his adaptability is very strong.

In the first week of life, most newborns will temporarily lose weight. This is because the baby drinks less milk at this time, and meconium and urine excretion, sweating and skin inhalation will destroy some human water. Short-term weight loss will occur two to four days after birth. It is called "pathological weight loss" in medicine and medicine, and generally the weight loss will not exceed 300 grams.

With the increase of milk volume, the baby's resting weight has just started to rise from the fourth and fifth days, and it can be restored to the resting weight at birth this week.

You can find that the baby's physical fitness exercise is not an independent and subconscious classic conditioned reflex. For example, when frightened by loud noise, the limbs can't help hugging the chest, which is the unique Moro reflex of newborn babies. By the end of this month, you may find that with the development trend of baby's whole body muscle control, his or her posture is gradually becoming a purposeful personal behavior. From birth to 56 days, the baby also has a wonderful skill-walking reflective surface. From the eighth day of birth, he can use this natural working ability to carry out various trainings, which can not only let the baby learn to walk well in advance, but also promote the development of brain and IQ.

Nutritional meal recipes suitable for 4-month-old children's development

The key ingredient for a 4-month-old baby is milk or formula milk powder. Adding complementary food to the baby must start from the beginning and gradually improve from one to more. WHO recommends that mothers with standards should breastfeed their babies until they are 6 months old, and then add complementary food. Let's take a look at the complementary food recipe for a four-month-old baby.

4-6 months is the baby's first contact with baby's complementary food. It's best to try something light first. Depending on the baby's growth and development, change the type and intensity of ingredients. Xiaomi soup, which is not easy to cause children's allergies, is the first baby food supplement that is more suitable for babies to try.

1, refreshing millet paste food: rice 15g. Practice: Wash the rice and soak it in warm water for two hours. Put the soaked rice into a blender, add a little water and stir it into fine rice slurry. Put the glutinous rice paste into a container. Pour the rice slurry into the milk pan, add about 8 times of cold water, and gradually heat it with slow fire. During the period, stir the rice slurry continuously with a spoon to prevent the bottom from being burnt. After the rice slurry is boiled, it can be cooked for another 2 minutes. Nutritional component reminder: Baby rice paste has the functions of invigorating spleen, regulating stomach and moistening lung, nourishing blood, nourishing yin and moistening lung, which is beneficial to the growth and physical and mental health of the body, can stimulate the metabolism of gastric acid, is beneficial to digestion and absorption, and has positive significance to the digestion and absorption of human fat. It can also promote the whey protein in infant milk powder to produce loose and soft small clots, which is very easy to digest.

2, Xiaomi soup food: Xiaomi mobile phone, water, accounting for (1: 10). Practice: Soak the millet phone for 30 minutes, then put it into the pot and cook it. After boiling, simmer for 40 minutes, then simmer for 10 minutes.

When cooking porridge with Xiaomi mobile phone, be careful not to be too thin.

4-month-old baby development index 2 height standard

After 4 months, the growth rate of the baby's height began to slow down. 1 month can increase by about 2 cm, but it is still relatively fast compared with the baby after 1 year. Remind parents not to worry about the baby's static height measurement once or 1 month, which doesn't mean anything. To know that the growth of height is continuous and dynamic, there is a saying that it grows first and then grows high.

Everyone knows the above introduction! How tall should a four-month-old baby be? You can compare it to see if the baby's height is normal.

Weight standard

The baby's weight can increase by 900 ~ 1250g at 4 months. Mark the measured weight on the growth curve and find out why it is lower than the 300th percentile or higher than the 97th percentile.

Head circumference standard

The baby's head circumference can be increased by about 1.4 cm this month. If the measured value is marked on the growth curve of the head circumference, and it is found that it exceeds the 97th percentile or is lower than the 300th percentile, it is necessary to take the baby to the hospital for examination to determine whether it is normal variation or has some diseases.

In daily life, some mothers are always worried when they see that their children's head circumference is smaller than other children's, because they think that a big head is one of the signs of intelligence. In fact, this view is one-sided, and the size of the head circumference is not directly proportional to the child's intelligence. However, the size of a child's head circumference is indeed related to brain development, which can reflect the size of a child's brain capacity. Generally speaking, during the period from birth to 2 years old, the head circumference grows rapidly, and it is too big or too small, or it grows too fast for a period of time. Parents should consider whether their children are ill. Therefore, parents must regularly measure their children's head circumference.

The baby's head circumference is related to intelligence, so parents should pay more attention to whether the baby's head circumference is normal or not, and pay more attention if it is abnormal.

Fontanel standard

Baby's fontanel is divided into front fontanel and back fontanel. The front fontanel is in front of the baby's head, diamond-shaped. When a baby is born, the front fontanel is only the size of an adult thumb. In the next few months, the baby's front fontanel grew rapidly. Under normal circumstances, the size of the baby's front fontanel should not exceed 3 cm, otherwise the baby's condition should be considered.

Chest circumference standard

By this month, the baby's chest circumference has been much longer than the head circumference, because by this month, the baby's head and chest organs have grown faster. This situation is normal, so mom and dad don't have to worry.

Average chest circumference of 3 ~ 4 months old baby.

Baby boy -4 1.2 ~ 42.3 cm.

Baby girl-40.1~ 41.1cm.

The average chest circumference of a 4-month-old boy is about 42.3 cm, and that of a girl is about 4 1. 1 cm.

The baby's physique varies from person to person.

In addition to the above introduction, of course, the baby's physique also varies from person to person. Some babies may develop faster and some babies may develop slower, so there is still a difference!

People's physique is different, including gender and personality, which is influenced by many factors such as heredity, spirit and nutrition.

The individual differences of people in infancy are even greater. Therefore, the evaluation of the baby's physical fitness standard should be carried out objectively and in two.

What to eat is good for baby's development?

1, agaric

Auricularia auricula, as the "king of iron supplementation" in the adult world (98 mg of iron per100g), is about 5 times higher than pig liver with the highest iron content in animal food and 30 times higher than spinach. However, the absorption rate of auricularia auricula is low, and auricularia auricula has the function of moistening intestines. Babies with weak stomach should pay special attention when eating.

2. Animal liver

Liver is the first choice to prevent iron deficiency anemia. High iron content and good absorption rate, easy to eat and digest, and not easy to cause allergies, especially suitable for infants. Pig liver has the highest iron content, which is 29. 1 mg per 100 mg, sheep liver is 17.9 mg, cattle liver is 8.8 mg, and chicken liver is the lowest, which is only 8.5 mg per 100 g chicken liver. However, it should be noted that animal livers are prone to accumulate toxins from animals themselves, so you must find the right reliable channels when purchasing.

3, blood tofu

Cooked animal blood clots are called "blood tofu", which is rich in nutrition and high in iron. The absorption rate is as high as 100 g of pig blood containing 260 mg of iron, which is equivalent to 10 times of the iron content in pig liver. It has been a good blood tonic since ancient times.

Special note: the latest research found that the human body's demand for iron is limited, and blood tofu should not be eaten in large quantities because of its high iron content; Second, animal blood is easy to accumulate toxins from animals themselves, so you must find the right reliable channel when buying.

4. Egg yolk

It is said that egg yolk is the best iron supplement food. However, scientific research has proved that egg yolk does contain iron, but its absorption rate is not impressive (7 mg of iron per100g of egg yolk, and the absorption rate of iron is only 3%). However, eggs are common foods, which are convenient to eat and store, and have high nutritional value, so they are good iron-supplementing foods.

The Best Period of Infant's Intelligence Development

Every parent wants their children to be born with a smart mind. You know, the influence of nurture on intelligence can not be ignored. As long as parents grasp the golden stages of their children's intellectual development and enlighten their children's intelligence, then the baby will naturally become smarter.

3-month-old children can focus on vision training.

Children have quick eyesight and unique observation. Parents should seize the critical period of vision development and train and guide their babies, which can improve their observation ability. It is understood that 3-month-old children have great potential for vision development. At this time, parents can expose their children to bright colors to stimulate their vision development. In addition, parents can hang some small wind chimes in front of their children's beds to guide their attention and develop their observation.

6 months to guide children's language expression.

Good language skills can strengthen children's expressive ability and make them communicate with others better. I believe many parents are looking forward to their babies learning to speak as soon as possible. However, children's language education needs parents' patience. In fact, children's language learning ability is inseparable from listening. Under normal circumstances, children will begin to babble after 6 months of growth, and then there will be some intermittent languages. Therefore, at this stage, parents can try to talk to their children more.

Pay attention to cultivating children's thinking guidance for 9 months

According to statistics, most children will begin to form their own thoughts after they grow up to nine months. If parents grasp this stage well and give their children correct guidance, it is very beneficial to their intellectual development. In daily life, parents can tell their children more logical story books. In addition, parents can prepare toys such as building blocks for their children, so that they can get exercise while playing games.
