A premature baby is an infant born before 37 weeks of pregnancy have been completed. A typical pregnancy lasts about 40 weeks, and babies born early may face various health challenges due to their underdeveloped organs. Premature birth can occur for several reasons, including multiple pregnancies, infections, or chronic health issues in the mother. These babies are often placed in a special unit called a neonatal intensive care unit (NICU), where they receive specialized care. The level of care needed depends on how early the baby was born and their specific health conditions. With advancements in medical technology, many premature babies grow up healthy and thrive.
