In a prospective study of 23 newborns with preauricular skin lesions, four (17 percent) had abnormal findings on brain-evoked response audiometry. 1 Another study of 178 newborns with isolated preauricular tags found that 23 (13 percent) had mild to moderate sensorineural hearing impairment.
Hunger is one of the most common reasons why your baby will cry (CKS 2014), especially if she's a newborn. The younger your baby is, the more likely it is that she's hungry. Your baby's stomach is small and can't hold very much. So it won't take long before it empties.
The most common lung problem in a premature baby is respiratory distress syndrome (RDS). This was previously known as hyaline membrane disease (HMD). A baby develops RDS when the lungs do not produce sufficient amounts of surfactant. This is a substance that keeps the tiny air sacs in the lung open. As a result, a premature baby often has difficulty expanding her lungs, taking in oxygen, and getting rid of carbon dioxide.
