  • Body hair
  • Episodes of absent breathing
  • Enlarged clitoris (female infant)
  • Lung problems such as neonatal respiratory distress syndrome
  • Poor feeding
  • Small scrotum, smooth without ridges (male infant)
  • Soft, flexible ear cartilage
  • Thin, smooth, shiny skin
  • Transparent skin (can see veins under skin)
  • Usually inactive -- however, may be unusually active immediately after birth
  • Weak cry
  • Wrinkled features

This list may not be all inclusive.

Exams and Tests

The infant may have a low body temperature and show signs of breathing problems.

Common tests performed on a premature infant include:
