According to statistics, most pregnancies last up to estimated 40 weeks. Babies born between 37 to 40 weeks gestation are hailed as full-term new born babes; and those who were born before the 37weeks of pregnancy period are called premature babies.
Presently, with the aid modern technology in medical field, the chance of giving birth to a premature baby can be until 23 weeks gestation. In many hospitals, this is the cutoff point of medical intervention wherein doctors can try to save the life of a premature born baby. Yet, this is a loose description based on general concept. A baby born before or at 23 weeks gestation requires extensive medical support: respiratory aid, invasive treatments and long, difficult stay in the Neonatal Intensive Care Unit.
