Impact of Premature Birth on Development Years ago‚ premature birth almost always meant death for the baby. Today‚ however‚ we have the technology to nurture these infants’ development‚ and many of them survive to lead normal‚ healthy lives. Although‚ very premature infants (that is‚ those born before about the fifth month) are still not likely to survive‚ many born at five months and older will thrive. Some preterm babies‚ however‚ do have many obstacles to overcome. There are a variety of
