Safe sleep is one of the most important ways to reduce sleep-related risks in infancy. Every caregiver should use the same routine for every sleep: back to sleep, a separate firm and flat infant sleep surface, and an empty sleep space.

Urgent Warning Signs - Check This First

If a baby is unresponsive, not breathing normally, blue or gray, or in immediate danger, call 911. Safe-sleep guidance reduces risk but does not replace emergency care for a baby who seems ill or is not acting normally.

CALL 911 NOW

  • A baby is unresponsive, not breathing normally, blue or gray, limp, has a seizure, or you believe the baby is in immediate danger

  • A baby is found face-down, wedged, trapped, or not responding after sleep. Call 911 and follow the dispatcher's instructions for CPR or rescue breathing

  • A baby has a serious injury, a major fall, choking with inability to breathe, or another emergency during sleep or feeding

GET EMERGENCY MEDICAL CARE NOW

  • A baby younger than 3 months (12 weeks) has a rectal temperature of 100.4 F (38.0 C) or higher, even if the baby otherwise looks well

  • A baby is very difficult to wake, is not alert when awake, has trouble breathing, is feeding much less than usual, has repeated vomiting, or looks seriously ill

  • A baby is sleeping in a position or device where breathing may be compromised and cannot be moved safely or is showing breathing difficulty

CONTACT YOUR CHILD'S HEALTHCARE PROFESSIONAL TODAY

  • You do not have a safe, separate infant sleep surface or are unsure whether a crib, bassinet, portable crib, play yard, mattress, or sleep product meets current safety standards

  • Your baby repeatedly falls asleep in a car seat, swing, stroller, carrier, or inclined product and you need help making a safer plan for travel, feeding, reflux, or daily routines

  • Your baby was born premature, has low birth weight, has a breathing, neurologic, or feeding condition, or has individualized sleep instructions from a healthcare professional

  • You have questions about swaddling, room sharing, a sleep monitor, baby positioner, sleep training, reflux, or a baby who seems uncomfortable lying flat

The Safe Sleep Routine

  • Place your baby on their back for every sleep - naps and nighttime - until the first birthday. Babies who can roll on their own may be left in the position they choose after you have placed them on their back

  • Use a firm, flat, level sleep surface designed for infants: a safety-approved crib, bassinet, portable crib, or play yard with a tight-fitting mattress and fitted sheet only

  • Keep the sleep space empty. No pillows, blankets, quilts, comforters, bumper pads, stuffed toys, wedges, positioners, mattress toppers, loose sheets, or weighted products

  • Room share, do not bed share. Keep the baby's separate sleep space in the caregivers' room, ideally for at least the first 6 months

  • Keep the baby's head and face uncovered and avoid overheating. Dress the baby for the room; do not use hats indoors for sleep

Places That Are Not for Routine Sleep

  • Adult beds, couches, sofas, armchairs, waterbeds, recliners, pillows, cushions, nests, and soft surfaces are not safe routine sleep spaces for babies

  • Car seats, strollers, swings, infant carriers, slings, and other sitting or inclined devices are useful for transport or supervised awake use, but not for routine sleep. If a baby falls asleep in one, move them to a firm, flat infant sleep surface on their back as soon as possible

  • Never sleep with a baby on a couch, armchair, or recliner. Do not leave a baby sleeping in an adult bed with another adult, child, or pet

  • Products marketed as making bed sharing safe, positioners, and inclined sleep products do not replace a safety-approved infant sleep space

Feeding, Fatigue, and Room Sharing

  • ·Keep the baby's separate sleep space near the adult bed to make feeding and comforting easier. Return the baby to their own sleep space when the feeding is complete

  • If you feel too tired to stay awake while feeding, avoid a couch, armchair, or recliner. Make a plan with another adult to return the baby to a separate safe sleep space

  • Do not use alcohol, cannabis, illicit drugs, or medicines that impair alertness when caring for a baby. Ask a healthcare professional about prescription or nonprescription medicines that may affect alertness

  • Do not allow smoking or vaping around the baby. Avoid smoke exposure during pregnancy and after birth

Swaddling and Tummy Time

  • If you swaddle, always place the baby on their back for sleep. The swaddle should not be tight around the chest or hips, and weighted swaddles or blankets should not be used

  • Stop swaddling as soon as your baby shows signs of trying to roll over. Never place a swaddled baby on the stomach or side to sleep

  • Give supervised tummy time every day while the baby is awake. Tummy time supports development and helps prevent a flat spot on the head; it is not a sleep position

A Safe-Sleep Check for Every Caregiver

  • Back to sleep every time

  • Baby sleeps alone on a firm, flat infant sleep surface with a fitted sheet only

  • Same room, separate sleep surface

  • No pillows, loose bedding, toys, bumpers, positioners, or weighted items

  • Every caregiver - family, babysitters, child care, and overnight visitors - uses the same routine

Call Preparation

  • Baby's age, birth history, medical conditions, medicines, feeding concerns, and whether the baby can roll

  • The sleep space and product name or photos: crib, bassinet, mattress, sleep product, car seat, swing, carrier, or monitor

  • Your usual sleep and feeding routine, caregiver arrangements, and the specific concern preventing the safe-sleep plan from working

  • Any symptoms that concern you: fever, breathing changes, feeding change, vomiting, poor weight gain, unusual sleepiness, or color change
