What is the development standard of a 42-day-old baby?

The health of the baby is the greatest comfort to the parents. The newborn baby will continue to grow with the change of time. At a certain stage, there will be certain development indicators. Only when this indicator is reached can the baby be considered healthy. So what is the development standard for a 42-day-old baby? If the baby does not reach the development indicator, what should parents do?

It is normal for a baby to gain 700 grams every month within six months after birth. So, if your baby's birth weight is 3350 grams, 4050 grams will be enough if he gains 700 grams. My baby is now 42 days old and weighs 9 jin, which actually means 4500 grams. There is no problem. As for height, it grows fastest within the first six months after birth, about 2.5 cm per month on average. If your baby was 50 cm tall when born and is now over 52.5 cm tall, it is normal and belongs to normal growth and development. The factors that affect the baby's development are: 1. Genetics: Genetic factors have a certain impact on the growth and development of children. For example, parents' height, skin color, amount and shape of hair all have a certain degree of influence on their children. 2. Mental factors: Experts believe that children who do not receive love and affection may have a lower average height than children of the same age because they secrete less growth hormone in their bodies. 3. Nutrition: Nutrition is essential for growth and development. Infants and young children need a reasonable diet structure, otherwise it will not only affect their normal development, but also affect their future intelligence. 4. Sleep: After children fall asleep, the anterior lobe of the pituitary gland will secrete a growth hormone. If you don't get enough sleep, your growth hormone may be blocked, leading to psychogenic dwarfism. 5. Exercise: Taking advantage of natural conditions for physical exercise plays a great role in strengthening children's physique, improving development levels and reducing incidence rates. Sunlight, air, and water can promote metabolism, digestion, absorption, and blood circulation, and are beneficial to growth and development. 6. Diseases: Long-term digestive disorders, repeated respiratory tract infections, endocrine system diseases and incomplete brain development have a direct impact on children's growth and development. 7. Environment and climate: Anthropological research has proven that people gain weight in autumn and grow taller in spring. From a regional perspective, tropical regions develop earlier, while frigid regions grow rapidly. In addition, a reasonable living system, fresh air, and an environment without noise and pollution are all beneficial to the physical and mental development of children. In daily life, babies should eat more foods rich in protein, iron, zinc and calcium.

Parents can refer to this data, but they cannot completely rely on or over-trust this indicator.
