We all hope that our future child will be an articulate and intelligent person. The child’s ability to speak is not only dependent on talent, but also on the development of the child’s natural abilities, which are best prepared from the time the baby is born. Therefore, when the child is still young, mothers and fathers should take the responsibility of developing the child’s various abilities. Babies change a lot in the first few months of life, sometimes so fast that mothers and fathers are very surprised, but continue to develop significantly after birth. Each month, babies grow perhaps 1/4 to 1/2 inch taller in varying degrees, and by the end of the first year, many babies will weigh three times as much as they did at birth. The baby’s head and chest grow faster than the lower half of the body, while the baby will gradually begin to gain fat as he or she grows, which is typical of development after birth, although certain factors can have positive or negative effects. Next, let’s take a look at the factors that affect the growth and development of babies. We hope to help all mothers and fathers. 1. Genetics At the most basic level, the length and growth rate of a newborn is determined to a very large extent through genetics. Weight is also related to genetic factors, but weight is also influenced by nutrition in some cases. There is no single gene that affects weight or length; each gene plays a small role, and when aggregated together, the effect is very large. If there were no other interfering factors, the newborn would grow along the genetically predetermined path. For example, if there were no interfering variables at all, European and American babies would grow faster than those of mixed Japanese and American descent. This is entirely determined by genetic factors. 2. Nutrition Compared to adults, babies eat less now, but the amount of nutrition they need to consume is twice as much as adults, and a quarter of the calories are used for the development of the baby’s body. However, if you do not let your baby get enough food in normal life, or if the quality of food is not very good, then the consequences are not up to the needs of the baby’s growth and development, so to a large extent their growth will be inhibited. Breastmilk provides all the nutrients your newborn needs to thrive. It is very comprehensive compared to formula, easy to digest and promotes the development of the immune system. Powdered milk provides many of the same nutrients as breast milk. Babies fed with milk develop very well, although it is important to note that vitamins and minerals still need to be supplemented. 3, and the relationship between the parents of the newborn and the interaction between mom and dad is very important for the physical development of the baby. If the mother and father are not close to the child, angry or unaccepting, the baby may have a “failure to thrive” condition. Babies with less genuine emotional contact with people will actually gain weight and grow slower than those who feel more love. There are also some medical problems that may cause this condition, such as brain damage, heart, lung or gastrointestinal problems, chromosomal abnormalities, etc. 4. Premature birth If the baby was born before 37 weeks of gestation, then such a child is a premature baby. Depending on the overall health of the baby and the time of prematurity, physical development may also have some impact. At least two to four months after birth, a premature baby will develop as if he or she were in the womb. Premature babies’ lungs are usually not fully developed and take several months to develop. Also, very many preterm infants are slow to gain weight and size, and it usually takes almost two years for them to catch up to the height and weight of a child born at full term.
