This is never an easy topic. SIDS, or Sudden Infant Death Syndrome, is when an infant one year or younger dies an unexplained death during sleep. There is nobody to blame for this type of death, but there are safe sleep guidelines that do reduce the risk of SIDS. Newborns can sleep up to 16 hours a day, so they spend much of their time sleeping. They sleep in three to four hour increments and need to eat often, but added all together, they sleep most of the day. It is important to keep the sleeping area for your baby as safe as possible.
