The care of premature babies is very important. Since the physical resistance of premature babies is weaker than that of full-term infants, premature babies generally need to be placed in incubators to maintain body temperature. If an incubator is not available, methods such as using a hot water bottle for warmth can be employed, or putting cotton hats on the babies. During feeding, breastfeeding is an option. For very small babies who have poor sucking ability or uncoordinated swallowing functions, or for babies who are ill, the mother can express her milk, which can then be fed to the baby via a tube through the nose. Artificial feeding is also an option.
