Key facts about safe sleep checklist every parent should know
Below is the short, evidence-based summary on safe sleep checklist before you read the full guide. Skim these first — they cover 90% of the questions parents actually ask.
The Empty Crib Rule — AAP Safe Sleep Checklist
Written by Dr. S. Xishan, MD, FAAP — Board-Certified Pediatrician & Neonatologist (Weill Cornell/NYP). Medically reviewed July 2026.
Sudden Infant Death Syndrome (SIDS) is the sudden, unexplained death of an infant under 1 year of age during sleep. It remains the leading cause of death in infants between 1 month and 1 year of age in the United States, with approximately 3,400 sleep-related infant deaths occurring annually.
The good news: the majority of these deaths are preventable. Since the AAP launched the “Back to Sleep” campaign in 1992, the SIDS rate has decreased by more than 50%.
The Safe Sleep Checklist
Use this checklist for EVERY sleep period — naps and nighttime. Consistency matters.
1. Back to Sleep
- The baby is placed on their back for every sleep period.
- Side sleeping is NOT safe. Stomach sleeping is NOT safe.
- Once the baby can independently roll both ways (typically 5-7 months), they may remain in the position they roll into — but always START them on their back.
2. Firm, Flat Sleep Surface
- The mattress is firm — it does not conform to the shape of the baby’s head or body.
- The mattress is flat — no incline, no wedge, no elevation. Inclined sleepers are BANNED (CPSC, 2019).
- The mattress fits snugly in the crib — no more than two fingers’ width of gap.
3. Empty Crib
- NO blankets, pillows, stuffed animals, crib bumpers, positioners, or loose bedding.
- Dress the baby in a sleep sack or wearable blanket instead of loose blankets.
4. Room-Sharing Without Bed-Sharing
The baby sleeps in the parents’ room on a separate sleep surface for at least the first 6 months, ideally the first year. Room-sharing reduces SIDS risk by up to 50%.
5. Temperature: 68-72°F (20-22°C)
- Maintain the nursery at 68-72°F.
- Dress the baby in no more than one additional layer than you would wear.
- A fan in the room is associated with a 72% reduction in SIDS risk.
6. Smoke-Free Environment
No smoking during pregnancy, in the home, or in the car. Maternal smoking during pregnancy is one of the strongest risk factors for SIDS.
7. Pacifier at Sleep Times
Offer a pacifier at nap time and bedtime. Pacifier use during sleep is associated with a significant reduction in SIDS risk. If breastfeeding, wait until it is well established (3-4 weeks).
8. Breastfeeding (If Possible)
Breastfeeding is associated with approximately a 50% reduction in SIDS risk. Any amount is protective.
9. Immunizations Up to Date
Immunized infants have a lower risk of SIDS. Vaccines do not cause SIDS — they reduce the risk.
10. Avoid Overheating and Head Covering
The baby’s head is uncovered during sleep. Hats are not recommended during sleep indoors.
Products That Are NOT Safe for Infant Sleep
- Inclined sleepers (Rock ‘n Play, Boppy Sleeper) — BANNED by CPSC.
- Crib bumpers — BANNED by CPSC (2022).
- Positional devices, wedges, nests — introduce suffocation risk.
- Soft/plush mattresses — rebreathing risk.
- Loose bedding — use a sleep sack.
- Car seats, swings, bouncers — not safe for unsupervised or extended sleep.
- Smart socks claiming to prevent SIDS — no consumer device is FDA-cleared for SIDS prevention.
Pediatrician’s Take
The safe sleep guidelines are not suggestions — they are the evidence-based minimum requirements for reducing the risk of SIDS. The five most impactful practices are: back to sleep, firm flat surface, empty crib, room-sharing, and a smoke-free environment. If a product is not a firm, flat mattress with a fitted sheet, it does not belong in the crib.
When to Call the Doctor
- You are unsure whether your sleep setup meets safe sleep guidelines.
- Your baby has a condition that makes back sleeping difficult (severe reflux, airway malformation).
- You have questions about transitioning from a bassinet to a crib or from a swaddle to arms-out.

Frequently Asked Questions
What is the AAP safe sleep checklist?
Alone (no adults, siblings, pets, or objects), on the Back, in a Crib with a firm flat mattress and only a fitted sheet, in a smoke-free room at 68-72°F, ideally room-sharing (not bed-sharing) for 6-12 months.
How does room-sharing prevent SIDS?
Sleeping in the parents’ room on a separate surface for the first 6-12 months cuts SIDS risk by up to 50% by supporting easier response to breathing changes and feeding cues.
Are crib bumpers safe?
No. The CPSC banned padded crib bumpers in 2022 due to suffocation, entrapment, and strangulation risks. Mesh liners are also unnecessary and not recommended.
What temperature is safest for baby sleep?
68-72°F (20-22°C). Overheating is a known SIDS risk factor. Dress your baby in one layer more than you’d wear yourself and use a sleep sack instead of loose blankets.
Safe Sleep Myth-Busting: What Parents Get Wrong
Several persistent myths about infant sleep safety continue to put babies at risk. Myth one: Bed-sharing is safe if you are a light sleeper and do not drink or smoke. Fact: The American Academy of Pediatrics recommends against bed-sharing regardless of these factors, because the risk of suffocation, entrapment, and SIDS is increased in any bed-sharing scenario. Myth two: Side-sleeping reduces the risk of choking. Fact: The back-sleeping position is safest for all babies because it reduces the risk of SIDS without increasing the risk of choking. Healthy babies naturally swallow or cough up fluids. Myth three: Swaddling prevents SIDS. Fact: Swaddling can help with sleep but does not prevent SIDS. In fact, swaddled babies should be placed on their backs and swaddling should stop when the baby shows signs of rolling. Myth four: Sleep positioners and wedges prevent SIDS. Fact: Sleep positioners, wedges, and rolled blankets are not recommended by the AAP and can increase the risk of suffocation. Myth five: Co-sleepers and bedside sleepers are safer than cribs. Fact: While bedside sleepers are safer than bed-sharing, a separate crib or bassinet in the same room is the safest sleep arrangement. Understanding these myths helps parents make informed decisions about their baby’s sleep environment.
Room Sharing vs. Bed Sharing: Understanding the Difference
The American Academy of Pediatrics makes a clear distinction between room sharing and bed sharing. Room sharing means placing your baby crib, bassinet, or play yard in your bedroom so you are in the same room but on separate sleep surfaces. The AAP recommends room sharing for at least the first 6 months and ideally the first year of life. Room sharing reduces the risk of SIDS by up to 50 percent, possibly because parents are more aware of their baby breathing and because the baby is less likely to enter deep sleep states associated with SIDS. Bed sharing, which means sleeping on the same sleep surface with your baby, is not recommended under any circumstances by the AAP. The risk of suffocation, entrapment, and SIDS is significantly higher in bed-sharing situations. The risk is highest for babies under 4 months, for premature babies, for babies with low birth weight, and when the parent smokes, uses alcohol or medications that cause drowsiness, or is excessively tired. Even in the absence of these risk factors, bed sharing is not recommended because the risk of accidental suffocation is always present. The AAP does recognize that some parents will choose to bed share despite the recommendation, and they provide guidance for making bed sharing as safe as possible. However, the safest sleep arrangement for your baby is a separate crib or bassinet in your bedroom. Room sharing provides the benefits of proximity without the risks of sharing a sleep surface.
