1. How to monitor height at home?
According to the measurement standard of children's health care physique in China, infants under 3 years old are measured lying flat, and children over 3 years old are measured standing. The World Health Organization (WHO) requires that people under 2 years old lie down and those over 2 years old stand.
Length: The baby should be placed on the measuring bed. When measuring, the baby's head should be fixed so that the top of the baby's head touches the headboard, facing upwards, and the ears are at the same level. Press the knee to make the lower limbs contact and cling to the bottom of the measuring bed. Move the skateboard so that it touches the soles of the feet. Record the number of centimeters between the top of the head and the soles of the feet, which is the body length.
Height: Use an altimeter or draw a ruler on the wall at home to measure height. Before measurement, you should also take off your coat, shoes and hat, take off your headdress and untie your braids. Let the child stand at attention, eyes look straight ahead, arms droop naturally, heels close together, toes slightly apart, and hold the chest and abdomen. After confirming that the child's heel, hip, scapula and occipital bone are close to the column, the surveyor puts down the top plate, so that the top plate gently touches the child's skull top, and then reads with an accuracy of 0. 1cm. Note that when reading, the surveyor should look at the same level as the roof. Similarly, the error of two consecutive measurements should not exceed 0.4cm.
After learning about height measurement, let's talk about how to measure weight.
Second, children's weight is one of the important indicators to reflect their nutritional status, and it is also the easiest to get data on nutritional status.
1. First, calculate the child's weight according to the law of weight growth.
Normal full-term babies weigh between 2000 and 4000 grams at birth. In the first three months, their weekly weight increased by180-200g, by150-180g in four to six months and by 90-120g in six to nine months.
1-2 years old, the baby's weight increases by 2500-3000 grams on average, and increases by about 2000 grams every year after 2 years old until puberty.
According to the multiple of weight gain, the baby's weight is twice that at birth at 6 months, about 3 times at 1 year, and about 4 times at 2 years old.
Formulas can also be used to calculate:
Weight within 6 months = birth weight+month age × 600g
Weight of 7- 12 months = birth weight+month age × 500g.
2-7 years old weight = age × 2+8000g.
2. After calculating the child's weight, actually measure its weight.
Methods of testing children's weight:
When weighing, you need to choose scales with different accuracy according to your child's age.
● Newborns should choose an electronic platform scale, which needs to be accurate to1g.
● Infants should choose electronic platform scale or seat scale, which should be accurate to 10g.
● Children and adolescents choose standing electronic scales, which need to be accurate to 50g.
Before each measurement, the balance must be placed horizontally and safely, and the balance must be zeroed and corrected. Before weighing, children should try to take off their coats and shoes, and babies should change into clean diapers. Child care doctors should be familiar with the approximate weight of children's underwear, and deduct the weight of underwear that can't be taken off after weighing.
When weighing, newborns should lie in the middle of the scale, babies should lie or sit in the middle of the scale, and older children should stand in the middle of the scale. The surveyor should not touch the child, and be careful not to let the child touch other objects or cry and twist. He should try to calm the children down for a period of time, and let the data displayed on the weighing scale stabilize before reading.
It is best to measure it twice continuously, and the difference between the two weight measurements of infants and young children should not exceed 10g. If there is a big difference between the two measurements, it should be re-measured. The hardest thing to weigh is 1-3-year-old children. The electronic seat scale can display stable readings quickly and relatively safely, which is helpful to measure the weight faster and more conveniently, but it must be measured twice continuously to avoid mistakes.
After measuring every month, make records. If any abnormality is found, please ask a child care expert to find out the reason in time.
