Many parents feel that the baby’s growth should be doubly cared for, so all kinds of nutrition should be supplemented, but sometimes they are afraid that the baby’s development is over the limit, how to break? The author today and all the parents talk about the baby weight development of those things. A general baby’s normal weight standard As we all know, one of the elements of eugenics is that the birth weight of newborns should reach normal standards, the current normal value of newborn birth weight should be 2500 grams to 4000 grams, female newborns are lower than male 110 grams. The average birth weight of newborns is about 3kg, and the fastest growth in the first six months after birth, with an average increase of 600-800g per month. 300-400g per month in the second half of the year, and twice the birth weight at 3-5 months (6kg), increasing to 3 times the birth weight at 1 year of age (9kg). The formula for calculating the weight of a child within 1 year of age is: 1-6 months weight (kg) = birth weight (or 3 kg) + month age × 0.6 (kg) 7-12 months weight (kg) = birth weight (or 3 kg) + month age × 0.5 (kg) 4 times the birth weight (12 kg) at 2 years of age. weight increases steadily after 2 years of age until 10 years of age, with an average annual increase of 2 kg. the formula for calculating the weight of a child is Yes: 2-10 years weight (kg) = age × 2 + 7 (or 8) Second, what is the general rule of infant weight gain? Weight gain reflects the nutritional status and is a sign of the child’s good growth and development, as well as a measure of milk sufficiency. Weight gain in infancy is a peak, and the younger the baby, the faster the weight gain. The baby’s weight gain occurs in the first week after birth, when the baby loses weight. In the first few days after birth, due to insufficient intake of nutrients, meconium and water loss, temporary weight loss can occur, medically known as “physiological weight loss”, to the 3rd to 4th day after birth, the weight loss can reach 6-9% of the birth weight. For example, the birth weight of 3700 grams, 3-4 days after birth may be reduced by 222-333 grams, and then quickly return to the original level. If the weight loss is too much or does not return to the birth level by the 10th day after birth, you should quickly find the cause and take the child to the neonatologist. However, as the baby grows, during the first few weeks, if there is enough milk, the baby’s weight increases by an average of 115-200 grams per week. During the first 3 months, the baby gains 180-200 grams per week, 150-180 grams per week from 4-6 months, 90-120 grams per week from 6-9 months, and 60-90 grams per week from 9-12 months. In terms of weight gain multiples, babies weigh twice as much at birth at 6 months, about 3 times as much at 1 year, about 4 times as much at 2 years, and about 4.6 times as much at 3 years. Third, what are the factors that affect the weight of the baby? Factors affecting the birth weight of newborns are mainly the following: 1, the age of first birth: the age of first birth is below 30 years old, the birth weight of newborns increases with maternal age, and decreases with age over 31 years old. 2, gestational week: the fetus in the mother’s body for too short or too long, will affect the birth weight of newborns. From 35 to 39 weeks of gestation, the birth weight of the newborn increases significantly with the week: from 40 to 43 weeks of gestation, the weight increases more slowly; after 44 weeks of gestation, the weight decreases instead. 3, the number of births and multiple births: the birth weight of the second fifth child compared with the first child, an incremental phenomenon, multiple births are generally lower weight. 4, maternal health status: pregnant women suffering from hypertension, heart disease, kidney disease and other diseases, low birth weight of newborns. If infected with viruses or other microorganisms, will also affect the development of the fetus. 5, maternal hobbies: pregnant women smoking can lead to lower than normal weight of the newborn. 6, fetal sex: female newborns are lower than male 110 grams. 7, nutritional status: dieting, partial eating, picky eating can cause nutritional deficiencies and lead to low weight of the newborn. Fourth, what should I do if my baby is overweight? If you are told by your doctor that your baby is overweight or at risk of being overweight, you need to take measures to control your baby’s weight. The reason your baby is overweight is that he or she takes in more energy than he or she consumes. Parents can regulate your baby’s diet and encourage your baby to do more exercise. Babies are active by nature, and most toddlers are not idle throughout the day, but some babies are lazy and parents need to supervise them a little more. If your baby is already in kindergarten, parents should check with the teacher to see how much activity your baby gets during the day. If the activity level is not enough, parents can take the baby for a walk in the park and let the baby run more to burn calories. In addition to exercise, parents need to make reasonable adjustments to their baby’s diet. Make a record of your baby’s daily diet and calculate his or her energy intake based on what he or she eats. If your baby’s calorie intake exceeds the limit in a day, you need to reduce the intake of some snacks and drinks, and make a reasonable nutritional mix of ingredients in regular meals. Don’t let your baby eat too many snacks, especially sweets, between meals. Give your baby more fresh vegetables and fruits, and try to replace high-calorie snacks with fruits as snacks. If your baby is a picky eater and doesn’t like vegetables, try making vegetable soup or fruit and vegetable juice for him. As your baby gets older, he will likely be more open to eating vegetables if you let him shop, pick and cook with you. It is important to note that if your baby enjoys sucking on the bottle, watch out for your baby drinking more milk than his body needs. Full-term lesions only need to consume about 350 to 500 ml of milk per day. If the amount is excessive and your baby still wants to drink, you can give your baby some diluted drinks instead. Babies can start drinking semi-skimmed milk at the age of 2. Semi-skimmed milk contains less fat and fewer calories.
