  • Prenatal exposure to drugs or alcohol: Exposure to certain substances before birth can have long-term effects on an infant's brain development and behavior.
  • Premature birth: Infants born prematurely may have a higher risk of developmental delays and health problems.
  • Low birth weight: Infants born with low birth weight may have a higher risk of health problems, such as respiratory issues and feeding difficulties.
