Safe sleep
Guidance on placing babies on their back, on a firm flat surface, with no pillows, bumpers or loose bedding.
Safe sleep refers to widely published guidance, including recommendations from the American Academy of Pediatrics, on how to reduce sleep-related risks for infants. The core points are placing a baby on their back for every sleep, on a firm and flat surface, in a space free of pillows, blankets, bumpers, stuffed animals and other loose or soft items.
This guidance matters just as much in a small apartment or shared bedroom as it does in a large nursery. Room sharing, keeping the baby's sleep space in the same room as a parent without bed sharing, is one of the points included in this guidance, which is part of why bassinets and bedside sleepers are common in compact homes. The sleep surface itself, whether a crib, bassinet or pack 'n play, should be one designed and sized for infant sleep.
When setting up any sleep space, check that the mattress is firm and fits the frame tightly with no gaps, and keep the area clear of extra items, including crib bumpers and positioners. This guidance is published by pediatric health organizations and evolves over time, so it is worth checking current recommendations directly from a source like the AAP or your pediatrician rather than relying only on product packaging. A common mistake is adding blankets or padding for warmth or comfort, which the guidance advises against for young infants.
