One of the biggest concerns for new parents, especially first-time ones, is keeping their little ones safe while they're sleeping. Sudden Infant Death Syndrome, or SIDS, can occur if a baby isn't positioned properly in the crib or suffocates in bedding or stuffed toys in the crib. That's why the Consumer Product Safety Commission advises that "Bare is Best." The CPSC warns against placing thick quilts and pillows in any sleep environment, including bassinets, cribs and play yards.
Some parents, in an effort to keep their child safe, purchase sleep positioners. These are designed to keep babies positioned in a way that won't cause suffocation. Some are flat, while others are slightly inclined and have side bolsters.
