Premature birth generally does not affect a baby's intellectual development, as the brain is mostly well-developed by the time of premature birth, and intelligence is not greatly affected. With appropriate nutrition post-birth, the intelligence of premature babies can generally recover to that of average children. However, if the baby experiences intrauterine hypoxia during premature birth, this can affect the brain cells and may even lead to cerebral palsy. Therefore, it is important to closely monitor the baby's diet and neurological responsiveness if premature birth occurs. If there are concerns, a hospital check-up can be conducted to promptly identify any issues with the child.
