The American Academy of Pediatrics recommends that babies sleep on their backs to reduce the risk of Sudden Infant Death Syndrome (SIDS). This is the safest sleeping position for infants up to one year old. It helps keep their airway clear and reduces the likelihood of suffocation. While some parents may worry about flat spots developing on the back of the baby's head, this can be prevented by providing plenty of supervised tummy time when the baby is awake and alert. It's important to avoid letting your baby sleep on their side or stomach as these positions increase the risk of SIDS. If your baby has reflux or other medical conditions that require them to sleep in a different position, consult with your pediatrician for guidance. Remember, always prioritize safety when it comes to your baby's sleeping habits.
