Whether the development of preterm infants and normal babies is the same, it mainly depends on how long the preterm birth, if the preterm birth is too early, then the growth and development of preterm infants will still be affected to a certain extent, if the time of preterm birth is not too early in advance, in general, it does not affect its growth and development, and the difference between the normal baby is not very big. China’s more than 28 weeks of gestational age but less than 37 weeks, weighing 1,000g-2499g of newborns called preterm babies. If the preterm baby is born at the end of 28 weeks, its growth and development will be affected by a relatively large, because the birth of the baby in the uterine cavity of the time is too short, not in the uterine cavity to take in enough nutrients, resistance is very weak, although there is respiratory movement after birth can survive, but after birth is prone to idiopathic respiratory distress syndrome, its growth and development is limited. If born between 32-36 weeks, its viability is greatly enhanced, the development will be much healthier than the end of 28 born at the end of the week, but there are still subtle differences with the normal fetus, but proper care in the later stages of the proper feeding, there is generally no significant difference. If the baby is born at the end of 36 weeks, there is basically no significant difference with the fetus born in normal gestational weeks. Preterm babies are born early, usually pay attention to the following points: prevent infection, pay attention to warmth, breastfeeding, and petting the baby, which is conducive to the healthy growth of preterm babies.
