Height standard

At 4 months, the growth rate of the baby's height begins to slow down. It can grow by about 2 cm in 1 month, but it will not be the same as after 1 year old. Compared with my baby, it is quite fast. Parents are reminded not to worry about the baby's abnormal height measurement once or in one month. This does not mean anything. You must know that the growth of height is continuous and dynamic, and it is said that it grows first and then grows.

Everyone knows the above introductions! What should be the height of a four-month-old baby? You can check to see if your baby's height is normal.

Weight standards

The weight of a 4-month-old baby can increase by 900 to 1250 grams. Mark the measured weight on the growth curve. If it is below the 3rd percentile or above the 97th percentile, look for the reason.

Head circumference standard

During this month, the baby's head circumference can increase by about 1.4 cm. If you mark the measured value on the head circumference growth curve and find that it exceeds the 97th percentile or is below the 3rd percentile, you need to take your baby to the hospital for examination to determine whether it is a normal variation or a disease. certain diseases.

In daily life, some mothers are always worried when they see that their children’s head circumference is smaller than that of other children, because they believe that a big head is a sign of intelligence. In fact, this view is one-sided. 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, and it can reflect the size of the child's brain capacity. Generally speaking, from birth to 2 years old, the head circumference of a baby grows rapidly. If the head circumference is too large, too small, or the head circumference grows too fast within a period of time, there will be problems. Parents should consider whether the child has Sick. Therefore, parents must measure their children's head circumference regularly.

There is a relationship between the baby's head circumference and intelligence, so parents should pay more attention to whether the baby's head circumference is normal. If it is abnormal, they should pay more attention.

Fontanel standards

The baby's fontanel is divided into anterior fontanel and posterior fontanel. The anterior fontanel is located at the front of the baby's head and is shaped like a rhombus. When a baby is born, the anterior fontanelle is only the size of an adult's thumb. In the following months, the baby's anterior fontanel grows faster. Under normal circumstances, the size of the baby's anterior fontanel should not exceed 3 cm, otherwise the baby's illness must be taken into consideration.

Bust girth standards

By this month, the growth of the baby's chest circumference exceeds that of the head circumference, because by this month, the baby's head and chest organs grow faster. In this case It's normal, parents don't need to worry.

The average chest circumference of babies aged 3 to 4 months

Baby boys - 41.2 to 42.3 cm.

Baby girl - 40.1 ~ 41.1 cm.

The average bust circumference of a 4-month-old male baby is about 42.3 cm, and the average bust circumference of a female baby is about 41.1 cm.

Babies’ physiques vary from person to person

In addition to my introduction above, of course, babies’ physiques also vary from person to person, and some babies may develop relatively slowly. Fast, some babies may develop more slowly, so it’s still different!

People’s physiques are different. They have both sex and personality, and are affected by many factors, such as genetics, mental state, nutrition, etc.

Individual differences are greater in infancy. Therefore, the evaluation of the baby's physical standards must be done objectively and in two parts.

What to eat is good for your baby’s development?

1. Black fungus

As the "king of iron supplements" in the adult world, black fungus (98 mg of iron per 100 grams of black fungus) has the highest iron content among animal foods. of pork liver is about 5 times higher than spinach and 30 times higher than spinach. However, the absorption rate of black fungus is lower in comparison, and black fungus has an intestinal moistening effect, so babies with weak stomachs should pay special attention when eating it.

2. Animal liver

Liver is the first choice food to prevent iron deficiency anemia. It has high iron content and good absorption rate. It is easy to eat and digest, and it is not easy to cause allergies. It is especially suitable for babies. Pork liver has the highest iron content, with 29.1 mg per 100 mg, sheep liver has 17.9 mg, and beef liver has 8.8 mg. Chicken liver has the lowest iron content, with only 8.5 mg of iron per 100 g. However, special attention should be paid to the fact that animal livers tend to accumulate toxins from the animals themselves, so you must find the right reliable channel when purchasing.

3. Blood tofu

Boiled animal blood clots are called "blood tofu". It is rich in nutrients, has high iron content, and has a high absorption rate of 100 grams. Pig blood contains 260 mg of iron, which is equivalent to 10 times the iron content in pig liver. It has been a good blood supplement since ancient times.

Special reminder: The latest research has found that the human body’s demand for iron is limited. Blood tofu is not suitable for large amounts of food because it contains too much iron. Secondly, animal blood can easily accumulate toxins from the animal itself. , be sure to find the right reliable channel when purchasing.

4. Egg yolk

Rumor has it that egg yolk is the best iron-supplementing food. However, scientific research has proven that egg yolks do contain iron, but the absorption rate is not impressive (egg yolks contain 7 mg of iron per 100 grams, and the iron absorption rate is only 3%). However, eggs are common food, easy to eat and preserve, and contain various nutrients. The value is also high and it is a good iron supplement.

The best period for baby’s intellectual development

Every parent hopes that their children will be born with a smart mind. You must know that the impact of acquired training on intelligence cannot be ignored. As long as parents grasp the golden development stages of their children's intellectual development and provide intellectual enlightenment to their children, their babies will naturally become smarter.

Three-month-old children can focus on vision training

Children have sharp eyesight and naturally unique powers of observation. Parents should grasp the critical period of vision development and provide training and guidance to their babies to improve their children's observation skills. It is understood that children as young as 3 months old have great potential for vision development. At this time, parents can allow their children to be exposed to more brightly colored things to stimulate their children's visual development. In addition, parents can hang some small wind chimes in front of their children's beds to guide their children's attention and develop their observation skills.

Guiding children’s language expression in 6 months

Good language skills can strengthen children’s expression skills and enable children to communicate better with others. I believe many parents hope that their babies can learn to speak as soon as possible. However, children's language education requires parents to patiently instill. In fact, children's language learning ability is inseparable from the coordination of hearing. Under normal circumstances, children will start babbling after they grow up to 6 months old, and then some intermittent speech will continue to appear. Therefore, parents can try to talk more to their children at this stage.

Focus on cultivating children’s thinking guidance at 9 months

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