One of the best things parents can do to prevent sudden infant death syndrome (SIDS) is to create a safe sleep environment. The recommendations given by the UK health authorities, such as NHS Start for Life, Public Health Scotland, the Welsh NHS, the Lullaby Trust, and local NHS trusts, are consistent and evidence-based. Decades of research support these guidelines and are intended to assist parents in creating safe routines at birth.
- Back to Sleep – Every Sleep, Day and Night
Every single piece of official advice emphasizes that you should put your baby on their back to sleep at all times until they learn to roll in both directions.
- NHS Start for Life: Sleeping on the side or tummy is a major risk factor of SIDS.
- Parent Club and Public Health Scotland: Babies should never sleep in a sitting position (e.g. car seat, swing) unless in transit.
- Welsh NHS: Back-sleeping is a must, front or side sleeping is dangerous.
- Lullaby Trust: The back-to-sleep positioning is the most protective single measure.
- The Safest Sleep Location
Babies must sleep in a cot or Moses basket in the parents room-day and night at least the first six months.
- Do not sleep with your baby on sofas or armchairs because it increases the risk of SIDS significantly.
- Bed-sharing is not risk-free- when it is chosen, it must be done under optimal conditions (no-smokers, no alcohol/drugs, baby full-term and healthy, no loose bedding).
- UK Norms: Sharing a room is highly encouraged; bed-sharing occurs in about 50% of families, usually unintentionally, particularly among breastfeeding women.
- A Firm, Flat, and Clear Sleep Space
The cot or Moses basket ought to contain:
- A firm, smooth, waterproof mattress that is tight fitting.
- No pillows, duvets, cot bumpers, nests, pods or sleep positioners-these may suffocate or overheat your baby.
- Feet-to-foot positioning: The bottom of the cot is at the feet of the baby to avoid wriggling under the blanket.
- Bedding under the arms, and only to the armpits in case of blankets.
- Temperature and Overheating Prevention
Overheating is a key SIDS risk factor.
- Maintain room temperature between 16–20°C.
- Check baby’s chest or neck, not hands or feet, to gauge warmth.
- Use TOG-rated sleeping bags instead of loose blankets:
- Winter: 2.5–3.5 TOG + vest + sleepsuit.
- Summer: 0.5–1.0 TOG + lighter clothing.
- Winter hats are not recommended during sleep.
- Smoke-Free Environments
Across all UK health bodies, smoke exposure is one of the highest SIDS risks.
- No smoking in pregnancy, in the home, or in the car.
- Babies exposed to smoke-before or after birth-have a much higher chance of SIDS.
- Feeding and Soothing Practices
- Breastfeeding at least two months reduces the risk of SIDS by half; the greatest protection is exclusive breastfeeding.
- Dummy use can decrease the risk of SIDS, but should not be introduced until breastfeeding is well established (approximately one month) and then discontinued between 6-12 months.
- Do not replace a dummy once it falls out in the middle of the night.
- Day/Night Sleep Distinction
- Day naps: in the same room as caregiver, ideally with daylight and low background noise.
- Night sleep: Make the surrounding dark and silent, no stimulating activities.
- This aids in the gradual separation of day and night in babies.
- Avoiding Unsafe Sleep Situations
Never:
- Sleep with your baby on a sofa or armchair.
- Use unapproved items such as rolled-up towels, wedges, or bulky bedding.
- Share a bed if under the influence of alcohol, drugs, sedatives, or extreme tiredness.
- Co-sleep with premature or low birthweight babies.
- UK vs US/Australia Guidance Differences
- Co-sleeping: UK focuses on risk reduction rather than blanket prohibition (as in the US).
- Bedding: UK parents rely on sleeping bags with TOG ratings matched to temperature, rather than blankets layered over.
