Safe sleep advice can feel frightening when you are already tired and caring for a newborn. The goal is not to make parents anxious or promise that every risk can be removed. It is to build the same simple, evidence-based sleep environment for every nap and every night: place baby on their back, use a firm and flat infant sleep surface, and keep the cot completely clear.
What do SIDS and SUID mean?
Sudden infant death syndrome (SIDS) is the sudden death of a baby younger than 1 year that remains unexplained after a full investigation. Sudden unexpected infant death (SUID) is a broader term used when an infant dies suddenly and the cause is not immediately clear. After investigation, some deaths are attributed to SIDS, accidental suffocation or another cause.
Parents cannot predict SIDS by watching for a particular sound or movement, and no product can guarantee prevention. What families can do is reduce known risks. The American Academy of Pediatrics recommendations apply to healthy babies up to age 1 and focus on sleep position, surface, surroundings and caregiver circumstances.
The safest sleep setup for every nap and night
Back for every sleep
Put baby down on their back for naps and nighttime. Side sleeping is not stable, and tummy sleeping raises risk. Back sleeping does not increase choking risk in healthy babies, including babies who spit up.
Firm, flat and level
Use the mattress supplied or approved for the cot, crib or bassinet. It should return to shape when pressed, fit snugly with no trapping gap, and remain level—not inclined, hammock-shaped or padded.
Only a fitted sheet
The sheet should be made for that exact mattress and stay smooth at every corner. Do not place folded towels, blankets, waterproof pads or sleep positioners above or below baby to create padding or an incline.
A completely clear cot
Keep out pillows, loose blankets, quilts, duvets, cot bumpers, toys, nests, wedges, sheepskins and decorative cushions. Weighted blankets, weighted swaddles and weighted sleepwear are not safe for infants.
Never use a sofa, armchair, beanbag, cushion, adult mattress or recliner as an infant sleep surface. Sitting devices such as car seats, swings, bouncers, carriers and strollers are not recommended for routine sleep. If baby falls asleep in one, move them to their regular firm, flat sleep space as soon as practical.
Room sharing, bed sharing and exhausted nights
Keep baby’s cot or bassinet close to the caregiver’s bed, ideally for at least the first six months. This is room sharing: baby is nearby but has a separate infant sleep surface. It supports feeding and checking while avoiding adult pillows, blankets, mattress gaps and other people in the sleep area.
Bed sharing increases the risk of sleep-related death. The danger is especially high on sofas and armchairs, and when an adult smokes, has consumed alcohol, has taken sedating medicines or drugs, or is extremely tired. Risk is also higher for premature or low-birth-weight babies and babies younger than 4 months.
Night feeds are tiring. Plan before lifting baby: switch on a light, set a phone alarm if helpful, and avoid feeding on a sofa or armchair if you might doze. If you feed in bed and unexpectedly fall asleep, return baby to their separate cot as soon as you wake. Make sure grandparents, relatives, babysitters and domestic helpers follow the same rules; safe sleep must be consistent, not only when a parent is watching.
Warmth, swaddling and Indian weather
Overheating can increase risk. Use light, well-fitting sleep clothing suitable for the room rather than a loose blanket. A correctly sized, non-weighted wearable sleep sack may be used if baby’s head cannot slip through the neck opening. Keep the head uncovered indoors and check the chest or back of the neck; sweating, flushed skin, damp hair or a hot chest may mean baby is too warm.
In hot weather, light breathable clothing, ventilation, a fan or air conditioning can help. Keep direct airflow, electrical cords, curtain cords and hanging mosquito nets away from the cot. Never let fabric sag into the sleep space. In winter, add a suitable clothing layer or sleep sack instead of a loose razai, quilt, hot-water bottle or electric blanket.
Swaddling does not itself prevent SIDS. If you swaddle, always place baby on their back, keep the wrap light and non-weighted, allow hip movement, and stop as soon as baby shows signs of trying to roll—often around 3 to 4 months, but sometimes earlier. Once swaddling stops, use ordinary fitted sleepwear or a correctly sized arms-free sleep sack.
Feeds, rolling, reflux, travel and other everyday situations
| Situation | Safer response |
|---|---|
| Baby rolls independently | Continue placing baby down on the back. If baby can roll both ways unaided, you do not need to keep turning them back, but keep the cot completely clear and stop swaddling. |
| Baby spits up or has reflux | Healthy babies should still sleep flat on their backs. Do not raise the mattress or use a wedge; inclines can make the body slide and obstruct breathing. Ask a paediatrician about pain, poor growth or breathing concerns. |
| Baby sleeps in a car seat | Use the restraint correctly during travel. At the destination, transfer baby to a firm, flat sleep surface rather than leaving the seat to serve as a cot. |
| Staying with relatives | Arrange a proper infant cot, bassinet or portable play yard. Do not improvise with pillows on an adult bed, a sofa, a carrycot not approved for sleep or folded blankets on the floor. |
| Tummy time | Give tummy time only while baby is awake and actively supervised. Tummy time supports development; tummy sleeping is not safe. |
Other evidence-based ways to reduce risk
- Keep pregnancy and baby smoke-free. Avoid smoking and nicotine exposure during pregnancy and after birth, including in the home and car.
- Avoid alcohol, illicit drugs and sedating substances around sleep. They reduce an adult’s ability to wake and respond and make surface sharing especially dangerous.
- Attend antenatal and infant healthcare visits. Keep vaccinations up to date and discuss premature birth, low birth weight or medical conditions with the baby’s clinician.
- Offer human milk if it works for your family. Breastfeeding or providing expressed human milk is associated with lower sleep-related death risk, but every family still needs the same safe sleep environment.
- Consider a pacifier at sleep time. The AAP says offering one for naps and bedtime may reduce risk. If breastfeeding, wait until feeding is well established. Do not force it, reinsert it after baby falls asleep, or attach it to clothing, toys or cords in the cot.
Be cautious with products labelled “anti-SIDS,” “breathable” or “smart.” Marketing language is not proof that an item prevents death. A bare, safety-approved sleep space is more important than extra technology or bedding.
A 30-second safe-sleep check
- Baby starts the sleep on their back.
- The cot, crib or bassinet is approved for infant sleep and assembled correctly.
- The mattress is firm, flat, level, dry and snugly fitted.
- Only a tight fitted sheet is in the sleep space.
- There are no pillows, quilts, bumpers, toys, nests, positioners or weighted products.
- Baby’s head and face are uncovered and baby is not overheating.
- The cot is away from cords, heaters, hanging cloth and direct airflow.
- Baby is in the caregiver’s room but on a separate sleep surface.
- Every caregiver knows and follows the same setup for every sleep.
Frequently asked questions
Can a baby choke while sleeping on their back?
Healthy babies are not more likely to choke on their backs. Their airway anatomy and protective reflexes help manage spit-up. Back sleeping remains the recommended position unless the baby’s own specialist gives different instructions for a rare medical condition.
What should I do when my baby rolls onto their tummy?
Always begin sleep on the back. Once baby can roll from back to tummy and tummy to back independently, you can leave them in the position they choose. Keep the sleep space empty and stop swaddling as soon as rolling attempts begin.
Is room sharing the same as co-sleeping?
Terminology varies, so be specific. The recommended arrangement is room sharing without bed sharing: baby sleeps close to the caregiver in a separate cot, crib or bassinet. Sharing an adult mattress, sofa or armchair is not the safer arrangement.
Can I incline the cot for reflux or a blocked nose?
Do not incline the mattress or add a wedge. A baby can slide into a position that restricts breathing. Keep baby flat on their back and ask a paediatrician for help with persistent reflux, breathing trouble, feeding difficulty or poor weight gain.
Are baby monitors useful for preventing SIDS?
Audio and video monitors can help caregivers hear or see a baby, but consumer heart-rate and breathing monitors have not been shown to prevent SIDS. They must not justify tummy sleeping, soft bedding or bed sharing.
When can a baby use a pillow or loose blanket?
Keep the infant sleep area bare throughout the first year. When your child is older and transitioning to a toddler bed, discuss age-appropriate bedding with the paediatrician and continue to remove strangulation, entrapment and overheating hazards.
