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.
By the first month of life, most parents can tell if their baby's cry means hunger, pain, or anger. Crying also causes a nursing mother's milk to letdown (fill the breast). The amount of crying in the first 3 months varies in a healthy infant, from 1 to 3 hours a day. Infants who cry more than 3 hours a day are often described as having colic. Colic in infants is rarely due to a problem with the body. In most cases it stops by 4 months of age.
