Step-by-step explanation
Yes, Sudden Infant Death Syndrome (SIDS) is one of the leading causes of death in infants in the United States. SID refers to the unexplained death, usually during sleep, of a seemingly healthy infant. It is estimated that about two thousand infants die from SIDS in the U.S. each year. The exact cause of SIDS is still unknown, but researchers believe that there may be abnormalities in the part of the brain that controls arousal from sleep and breathing.
