Nowadays, many families have a child, and the growth of the child has become the core issue of the whole family. Is there any standard for height and weight when the baby grows up healthily? How to judge whether your child grows up healthily? What can help children grow taller at ordinary times? The following is a detailed introduction for you. Come and have a look ~
Standard table of infant height and weight
1. After birth, a normal child will weigh between 2,500 grams and 4,000 grams, and his length will be between 46 cm and 52 cm. Generally, his head circumference will reach 34cm, and his chest circumference will be smaller than his head circumference 1~2cm.
2. Temporary weight loss will occur 2 ~ 4 days after birth, which is medically called "physiological weight loss" and generally does not exceed 300 grams. With the increase of milk quantity, the baby's weight starts to rise from the 4th and 5th day, and can return to birth weight in this week.
3. The average weight of full-moon babies is 4.9 kg for boys and 4.6 kg for girls; The average length of a full-moon baby is 56.6 cm for boys and 55.6 cm for girls.
4. From birth to 1 year, the weight of the baby's brain is increasing at an average rate of 1000g per day. In these six months, it can increase almost 20W cells per minute. At this stage, we must pay attention to supplementing liver oil to children, which can prevent children from rickets. When you find that your baby likes to cry, and often wakes up at night, sweats a lot and can't sleep well, you must seek medical advice in time.
5. 13 weeks, the average weight of boys is 6.74 kg, and that of girls is 6.22 kg. The average height of boys is 62.4 cm, and that of girls is 6 1. 1 cm.
6. 17 weeks, the average height of boys is 64.5cm, and that of girls is 63. 1cm.
In July and May, the average weight of boys was 7.79 kg, and that of girls was 7.24 kg. The average length of boys is 66.3 cm, and that of girls is 64.8 cm.
8. The baby grows and develops in June. The average weight of boys is 8.39 Jin, and that of girls is 7.78 Jin. The average height of boys is 69.9 cm and that of girls is 68.3 cm.
After 9.7 months, the development standard of the baby is that the average weight of the boy is 8.69 kg and the average weight of the girl is 8.07 kg.
10.9 months, the average weight of boys was 9.22kg and that of girls was 8.58kg. ..
1 1. 10 months of growth and development, the average weight of boys is 9.44 kg and that of girls is 8.80 kg. The baby's body has also grown a lot. The average height of boys is 73.8 cm and that of girls is 72.3 cm.
12. 1 1 At the end of the month, the baby usually has 5-7 teeth. The average weight of boys is 9.65 kg, and that of girls is 9.02 kg.
The baby grows and develops in13.1February. By the end of 12, the baby should have 6-8 teeth. The average weight of boys is 9.87 kg, and that of girls is 9.24 kg. The weight of boys shall not be less than 7.79 kg, and that of girls shall not be less than 7. 18 kg. The average height of boys is 76.5cm and that of girls is 75. 1cm.
Basic law of body length growth index
Body length is the sum of the lengths of fingers, trunk and lower limbs. At different stages of the baby, the proportion of the three is different.
The average length of a baby at birth is about 50 cm.
1 year has the fastest growth, with an average monthly growth of 2.5cm in1-June and1.5cm in July-/February. At the age of one year, it increased by 25 cm, which was about 1.5 times of that at birth.
In the second year after birth, the growth rate of baby's body length began to slow down, and the annual growth rate was only 10- 12 cm.
From 2 years old to adolescence, the baby's body length increases by 6-7 cm on average every year.
The younger you are, the greater the ratio of head to upper body. With the increase of age, the lower body grows faster than the upper body.
The formula for calculating the body length of 2-7-year-old babies = age × 5+75cm.
Predicting adult height with children's length.
1. Male height = length at birth (cm)÷0.2949；; Female height = length at birth (cm) ÷ 0.438+009. It should be noted that this formula is only applicable to normal full-term newborns; If the length data can be accurate to 0. 1 cm, the prediction of height will be more accurate.
2. Male height =3 years old height ×0.545+ average height of parents × 0.544+37.69 (cm); Female height =3 years old ×0.545+ average height of parents ×0.544+25.63 (cm), and the prediction formula of human standard height (genetic law).
Male height = (father height+mother height) × 1.08÷2 (cm)
Female height = (father height ×0.923+ mother height) ÷2 (cm)
The above formula generally conforms to the genetic principle of "height increases to produce height, height increases to produce height, and height increases to produce height".
Intimate reminder
1. Take off shoes, hats and socks when measuring the baby.
It's better to measure in the morning, so it's easy to get more accurate values.
Infants under 3.3 years old can be measured by lying posture. When measuring, pay attention to straighten the knee joint and fix the head by hand.
Boys of the same age are longer than girls.

2. Sardines: the treasure house of protein. If the conditions are limited, you can eat crucian carp or fish floss;
3. Spinach is a "treasure house of vitamins";
4, carrots: children eat 100 grams a day, very beneficial;
