Step-by-step explanation:
When caring for mothers and newborns, there are several important factors to consider. First, the mother should take good care of herself and receive prenatal care, which includes regular medical check-ups and monitoring the health of both the mother and the fetus. It is also crucial for the mother to avoid toxic substances such as alcohol and provide all the necessary nutrients for normal fetal growth and development. Additionally, after birth, the newborn's system must adapt to the new environment, which is colder, brighter, and louder.
