Answer:
Preterm baby.
Step-by-step explanation:
According to the World Health Organization (WHO) a premature baby, which may also be called a preterm baby, is a baby born before 37 weeks of full gestation.
The more premature the baby, the greater the risks to his health as his organs and systems are not yet fully developed. But with the constant advances in medicine and the special care given to this population, their chances of developing normally and with a better quality of life are increasing.
