Safe Sleep for Your Baby: Essential Guidance for New Parents
Based on trusted advice from The Lullaby Trust and the NHS
Welcoming a new baby is a wonderful, busy and tiring time — and one of the most important tasks is ensuring your baby’s sleep is as safe as possible. While it’s natural to feel overwhelmed, following a few simple, evidence-based practices can significantly reduce the risk of serious issues like sudden infant death syndrome (SIDS). The Lullaby Trust and NHS set out clear steps you can follow for every nap and sleep.
1. The “ABCs” of Safe Sleep
The Lullaby Trust’s “ABCs” are a practical and memorable way to remember safe sleep practices:
- A: Always place your baby A on their back to sleep.
- B: Your baby should sleep in a B clear cot or separate sleep space that is free of pillows, toys, loose bedding or bumpers.
- C: Keep your baby in the C same room as you for at least the first six months (day and night) in a separate cot or Moses basket — not alone in another room.
Following these steps every time (for naps and overnight) helps build a consistent, safe sleep environment.
2. Sleep Position and Environment
- Always lay your baby to sleep on their back, from the very start — for both day and night sleeps. Side or tummy positions are known to raise the risk of SIDS.
- Use a firm, flat, waterproof mattress in the cot or basket. Avoid soft surfaces or inclined/tilted sleep positions.
- Keep bedding simple: a fitted sheet over the mattress is sufficient. Avoid duvets, pillows, cushions, cot bumpers, nests, pods or positioners. These can pose suffocation or entrapment risks.
- Place the baby “feet to foot” — feet at the end of the cot or Moses basket — and tuck any lightweight blankets under their arms so their head can’t slip under the covers.
3. Room Sharing — But Not Bed Sharing
- For the first 6 months, it’s safer for your baby to sleep in your room (i.e., same room) but in their own separate sleep space rather than in your bed. This helps you attend to them quickly and lowers risk of SIDS compared to sleeping in a separate room.
- Bed-sharing (sleeping in the same adult bed) increases risk especially if you or your partner smoke, have consumed alcohol, or taken drugs/medication that make you drowsy.
- Never allow your baby to sleep on a sofa or armchair with you — this is strongly linked with elevated SIDS risk.
4. Avoid Overheating & Head Covering
- Overheating is a known risk-factor. Make sure the room is at a comfortable temperature — typically around 16–20 °C is recommended.
- Avoid heavy sleep clothing or lots of blankets. A sleepsuit or baby sleeping bag of the correct tog is usually safer than loose blankets. In hotter weather, use lighter layers.
- Ensure your baby’s head remains uncovered while sleeping — bedding or hats that cover their face or head should be avoided.
5. Smoke-Free & Breastfeeding Benefits
- Exposure to tobacco smoke (during pregnancy or after birth) significantly increases the risk of SIDS. Keeping your baby in a smoke-free environment is critical.
- Breastfeeding is shown to offer protective benefits against SIDS. Even if you cannot or choose not to breastfeed exclusively, the benefits still apply.
6. Stay Consistent, Even for Naps
- The guidance applies not only to overnight sleep but every sleep — naps included. Inconsistent sleep positions (e.g., sometimes tummy, sometimes back) increase risk.
- When your baby starts to roll over both ways by themselves, you don’t need to keep them on their back — you can let them find their own sleep position. But until then, always place them on their back.
7. Practical Checklist for Safer Sleep
Here’s a simple checklist you can (and I recommend you do) share with parents on your site:
- Baby placed on their back, every sleep
- Separate sleep space: firm, flat mattress, fitted sheet only
- No pillows, duvets, soft toys, nests, or bumpers in cot
- Baby in the same room for at least first 6 months
- Room temperature comfortable (≈16–20 °C)
- Baby’s head remains uncovered
- Smoke-free environment at all times
- Avoid bed-sharing especially if smoke/ alcohol/ drugs are involved
- Breastfeed if possible
- Light layers for baby — check for overheating
8. Final Thoughts
Keeping your baby safe during sleep doesn’t mean being anxious or paranoid — it means being consistent. By following the clear advice from the Lullaby Trust and the NHS, you’re giving your baby the safest start you can. Aim for consistency, build a routine, and trust your instincts. You’re doing a great job.
