Detailed explanation of baby's one-and-a-half-year development index
Teeth: Most baby's primary teeth are 12.
Action: Be able to move forward freely and even run a few steps. I like to imitate the actions of adults. I like to put things together and often take a lot of things at once.
Hearing: When talking to parents or children around, the baby will raise his head, stare at the speaker's mouth and listen with interest.
Language: You can basically master 50- 100 words, and 50% of babies can master 60-80 spoken words. Be able to use two sentences flexibly and start using three sentences.

Nutritional advice for infants at the age of one and a half.
1, the food should be nutritious and easy to digest. Don't let children eat too sweet and sour food, because it is easy to cause loss of appetite and indigestion. Food should be made softer, from "powder, soup and mud" to "diced, diced and shredded". Don't eat foods that you shouldn't eat, such as irritating foods and dried whole fruits (such as peanuts, melon seeds, walnuts and dried beans). ).
2, 1 year-old-1.5-year-old baby is in the intellectual development period, so that the baby often eats some deep-sea fish (such as salmon, salmon, etc.). ), naturally there will be no lack of intellectual factors.
3. After1year old, eggs still can't replace the staple food. Some parents give their babies eggs almost every meal, which is unscientific. Excessive egg intake will increase the burden on the baby's gastrointestinal tract and even cause indigestion and diarrhea.
One-and-a-half-year-old baby growth and development comparison table 2 baby height and weight standard table
The growth law of infant height standard: the average length of full-term infants is 50 cm, which is about 25 cm in the first year after birth, so it is about 75cm； at one year old; After that, the average annual growth will be about 5 cm, so the length of children after 2- 12 years old (cm)= age ×5+75 (cm). Anyone whose height exceeds the standard 10% or is lower than 10% is regarded as abnormal.
Mom. Com reminder: Every baby's development will be different. Mom and dad should remember, don't force the baby to supplement nutrition or diet according to the standard!
Standard calculation method of baby's height and weight
After the baby is born, every stage of growth and development is the concern of parents. Mom and dad always want to know, is the baby too thin? Does he meet the standard? In which range is the head circumference normal? Understand the formula of baby's height, weight and head circumference, and monitor whether the baby's development reaches the standard at any time.
Standard formula for measuring baby's weight: 1-6 months' weight (kg)= birth weight (or 3kg)+ month age × 0.6 (kg); 7-65438+February weight (kg) = birth weight (or 3kg)+ month age × 0.5 (kg); 2- 10 years old weight (kg) = age ×2+7 (or 8).
The growth law of baby height standard: the average length of full-term baby is 50 cm, and it is about 25 cm in the first year after birth, so it is about 75cm； at the age of one; After that, the average annual growth will be about 5 cm, so the length of children after 2- 12 years old (cm)= age ×5+75 (cm). Anyone whose height exceeds the standard 10% or is lower than 10% is regarded as abnormal.
Standard formula for calculating baby's head circumference: the size of head circumference is closely related to the development of brain, and head circumference measurement can be used as one of the indicators of children's intellectual development. The formula is: head circumference = body length (cm)*4/ 10+ 15.
Factors affecting baby's height and weight
In addition to genetic factors, the baby's nutritional composition and sleep quality will also affect the baby's height and weight.
1, nutrition. When nutrition can't keep up with the baby's growth and development needs, the baby's body tissue will be affected. The most direct reaction is that the baby's bone growth slows down, and the height can't be reduced, and it can't meet the due standards. On the other hand, when there is excess nutrition, the excess nutrition will accumulate in the body, which will lead to the baby being overweight, which is also not conducive to health.
Step 2 sleep. Babies grow up most easily in sleep. If the baby's sleep quality is poor or insufficient, it will affect his height development. Under normal circumstances, newborns sleep about 20 hours a day; February-June is 15- 18 hours; June-65438+August, 13- 15 hours. Of course, if the baby lacks sleep, but his spirit is good, his mood and growth are normal, there is no need to follow this standard.
3. disease. Some babies' height and weight may be affected after some diseases: general acute diseases will affect their weight, and chronic diseases will affect their height. When the baby's height is always lower than the average baby's 10%, it means that the growth is slow; If it is lower than 30%, it needs timely diagnosis and treatment.
4. Exercise. Exercise can be said to be the key factor to promote the baby's growth. Exercise can promote blood circulation and accelerate the development and growth of bones. Therefore, after the baby is older, parents are advised to let the baby do some moderate exercise to promote development.
What should I do if my baby's height and weight are not up to standard?
The baby's height and weight are not up to standard. In addition to genetic factors, there are aspects such as nutrition, sleep and exercise. Therefore, it is very important to give the baby the right medicine and keep up with the "footsteps"! Parents can pay attention to the following aspects.
1, nutrition. You should ensure that your baby gets enough protein, carbohydrates and vitamins every day, especially animal protein. Because the lack of protein will directly affect the height growth. In addition, calcium, phosphorus and vitamin D are important material bases for bone growth. Milk contains both high protein and high calcium, which is a good food to promote growth.
Step 2 sleep. Sleep actually plays a particularly important role in the baby's growth and development, because for example, in every sleep cycle, growth hormone is secreted in the form of pulses during the sleep cycle.
3. Exercise. Exercise can promote the development and function of children's bones, muscles, joints and ligaments. Specifically, the baby can play kicking, rolling, crawling, or swimming, jumping, baby exercises and other sports on the bed. Mom and dad can often take their babies in the sun to promote the production of vitamin D in the body, thus helping the absorption of calcium.
4. sunshine. The baby's illness is also related to less sun exposure. Mom and dad don't have to worry that the sun will burn the baby's skin, just be careful not to let the baby bask for too long, and let the baby do more outdoor activities can also enhance the baby's physical strength!
Food that is conducive to the baby's growth.
For babies, comprehensive and balanced nutrition is very important. Only by taking enough nutrition can the baby have a good foundation for healthy development. Therefore, if the baby is short, parents need to work hard on food!
1, Carrots: Carrots are good friends when babies grow up. Carrots are rich in vitamin A, which contributes to the synthesis of protein. But babies generally don't like to eat whole carrots, so parents can make carrots into different dishes. For example, if you drink fruit juice, you can directly squeeze carrots or juice apples to neutralize the taste of carrots. In addition, when cooking chicken, pork and beef, you can also cut carrots into filaments and fry them together, which can not only flavor, but also be more nutritious.
2, eggs: eggs are recognized nutrients, especially egg white is rich in protein, which is very conducive to the growth of children. Some mothers worry that the cholesterol contained in egg yolk is not good for their children, but children in the growing period don't have to worry about the cholesterol value. It is ok to eat 1 egg every day or one egg every two days.
3. spinach: spinach is rich in iron and calcium. Many babies may not like spinach, so parents can try to chop it up and add it to other complementary foods.
4. Black beans: Soybeans are high-protein foods, and the protein content of black beans is higher, which is a good food for babies to grow up. Mom and dad can add black beans when cooking, or grind black beans into soybean milk for the baby to drink.
