What should a nurse advise a parent to do to prevent SIDS in their infant?

The recommendation to advise a parent to use a pacifier during an infant's sleep is based on evidence suggesting that pacifier use can be associated with a reduced risk of Sudden Infant Death Syndrome (SIDS). While the exact mechanism isn't fully understood, it is believed that pacifiers may help keep the airway open or promote arousal from sleep.

Using a pacifier during naps and bedtime can offer a protective factor against SIDS, especially if it is used consistently, and should be encouraged as part of an overall safe sleep strategy. Importantly, the pacifier does not have to be forced into the baby's mouth, and it can be removed once the infant is asleep.

Other sleep practices, such as placing an infant on their back to sleep, providing a firm mattress, and ensuring the sleep environment is free from soft bedding and pillows, are also crucial in preventing SIDS. While a pacifier can be beneficial, it should be used alongside these other recommendations for optimal safety.
