Safe sleep advice can feel overwhelming, especially when you’re navigating those early days with a new baby. In this baby safe sleep guide, Calm & Bright Sleep Support founders and our resident sleep experts, Gem and Eve, gently explain why safe sleep guidance exists and how to put it into practice with confidence.
Covering the questions parents ask most, this guide walks you through creating a safe, comfortable sleep space – from what your baby wears and how to manage temperature, to keeping their sleep area clear and comfy as they grow. You’ll also find practical tips for a calm bedtime routine, helping everyone enjoy more restful nights.
If you’ve ever found yourself, phone in hand, googling “Is this safe?” you’re not alone. Safe sleep advice can feel overwhelming. Conflicting posts. Well-meaning comments. Late-night spirals. That constant, quiet hum of Am I doing this right?
We hear this every day from real parents. Mums and dads who care deeply about their baby’s safety, who are trying so hard to do the right thing, yet still find themselves riddled with self-doubt.
That overwhelm is understandable. And it is not a sign you’re getting it wrong. It’s a sign that you care. And in a world overflowing with information, that care can easily tip into anxiety. Our role, as paediatric nurses, is to steady that.
A Steady Foundation You Can Trust
When it comes to safe sleep, there is clear, reliable guidance - and it exists to protect babies, not to frighten parents.
In the UK, safe sleep advice is led by the NHS and The Lullaby Trust. Their recommendations are based on decades of research into infant breathing, temperature regulation and risk reduction. At Calm & Bright Sleep Support, we follow this guidance closely. Not because we love rules - but because we understand why they exist.
We are registered paediatric nurses, regulated by the Nursing and Midwifery Council. We are also parents.
Our job as your Resident Sleep Expert is not to replace your instincts, but to help you trust them within a framework that’s grounded in evidence. To quieten the noise and help you feel confident in the choices you’re making every day.
Safe Sleep Was Never Meant to Feel Restrictive
Safe sleep is often shared as a long list of don’ts. Don’t add this. Don’t try that. Don’t get it wrong. And it’s no wonder that can feel confusing.
But safe sleep was never designed to make parenting harder. It exists to gently support babies while their bodies are still developing - and to give parents peace of mind during a time that can already feel fragile.
In the early months, babies are learning how to regulate their breathing and temperature. A calm, uncluttered sleep environment allows their body to focus on that work, without extra challenges.
At its heart, safe sleep guidance is simply about:
- keeping your baby’s airway comfortably clear
- supporting steady, easy breathing
- helping their body stay at a comfortable temperature
- offering extra protection while everything is still developing
Once those basics are in place, safe sleep can fade into the background. You don’t need to hover. You don’t need to constantly check. You can trust that the space is already doing its job.
The Real Questions Parents Ask About Safe Baby Step
(…and calm, evidence-based answers you can trust)
“How do I stop my baby overheating?”
This is one of the most common worries we hear - and for good reason.
In the early months, babies are still developing their ability to regulate their own body temperature. They don’t sweat efficiently yet, and they rely on us to help create a comfortable sleep environment.
Research consistently shows that overheating is a greater risk than being slightly cool, which is why safe sleep guidance focuses on room temperature, breathable fabrics and avoiding excess layers.
Babies generally sleep best in a room temperature of 16–20°C. Rather than adding blankets or layers “just in case”, it’s more protective to dress your baby appropriately for the room and then allow their body to do the rest.
This is where tog-rated sleepwear becomes incredibly helpful. Swaddles and sleep bags with clear tog guidance - such as those available at Mamas & Papas - take away the guesswork.
Pairing breathable sleepwear with a simple room thermometer, like the Tommee Tippee Gro Egg 2, allows you to check the room at a glance and then let the worry go.
If your baby feels comfortably warm on their chest or back (not hot or sweaty), that’s enough. You can trust that.
“Are sleep bags and swaddles actually safer than blankets?”
Yes - and the reason is very simple.
Loose blankets can move during sleep. Babies don’t yet have the head control or awareness to move fabric away from their face if it shifts, which is why blankets aren’t recommended in the early months.
Structured sleepwear, such as swaddles and sleep bags, stays in place. It keeps your baby warm without the risk of fabric covering their airway, which is why it’s consistently recommended within safe sleep guidance.
There’s also a comfort element here that often gets overlooked. Many babies find swaddles and sleep bags deeply soothing. The gentle containment can help reduce the startle reflex and recreate a familiar, held feeling in a predictable and safe way.
Options like the Mamas & Papas Dreampod Swaddle or the Love to Dream Swaddle UP® offer parents a simple, breathable alternative to traditional blanket swaddling. Zip-up designs and clear structure mean less uncertainty at bedtime and more confidence that your baby’s sleep space is safe.

“How do I know my cot or bedside crib is safe?”
This question almost always comes from love and responsibility, not from anything being wrong.
From a safe sleep perspective, what matters most is that your baby sleeps on a firm, flat mattress, with a well-fitted sheet, in a clear, uncluttered space.
Babies don’t need pillows, duvets, positioners or extras to sleep safely. In fact, the simpler the sleep space, the more protective it is.
Well-designed cots and bedside cribs support this by offering:
- a firm, supportive mattress
- breathable materials
- a flat sleep surface designed specifically for infants
Bedside cribs, such as the Mamas & Papas Lua Bedside Crib, can feel especially reassuring in the early months. They allow your baby to be close - supporting feeding, bonding and parental reassurance - while still offering a separate sleep space aligned with safe sleep guidance.
When parents feel confident in the sleep space, they often sleep more deeply themselves. And that matters. Rested parents are better able to respond calmly and intuitively during the night.
“What position should my baby sleep in?”
Babies should always be placed on their back to sleep. This is one of the most evidence-backed and protective pieces of safe sleep guidance we have.
Sleeping on the back helps keep the airway open and supports stable breathing and oxygen levels during sleep.
Once babies can roll independently, they will naturally move into positions that feel comfortable for them. You don’t need to reposition them or lie awake watching.
Your role is simply to place your baby on their back at the start of sleep - and then trust their growing capability.
“Am I doing it right?”
This is the question that sits quietly underneath all the others.
If your baby is:
- sleeping on their back
- in a clear, uncluttered space
- on a firm, fit mattress
- dressed appropriately for the room temperature
Then you are doing enough.
Safe sleep isn’t about perfection or constant checking. It’s about creating a supportive environment and then allowing yourself to step back.
Confidence matters more than people realise. Babies are deeply attuned to their caregivers, and when parents feel calmer and more assured, sleep often feels gentler for everyone.
Safe sleep isn’t about doing more. It’s about trusting the foundations you’ve already put in place. And once you trust those foundations, you’re allowed to rest, too.
A Calmer Way to Approach Bedtime
Safe sleep isn’t just about what your baby sleeps in. It’s also about how sleep feels.
Gentle bedtime cues help babies feel safe and ready to rest. A dim light, a familiar sound, a short bedtime story - these small, repeated signals tell your baby that it’s time to slow down.
Soft sleep aids, such as the Cloud B Lovelight Baby Sleep Soother, can offer gentle reassurance as babies grow and begin to recognise familiar sleep cues. Not to make babies sleep, but to support a calm, predictable environment.
Bedtime reading is another powerful tool. For newborns, it’s the sound of your voice that matters most. As babies grow, books become part of a familiar rhythm that helps bedtime feel safe rather than abrupt.
You don’t need a long story or a perfect routine. A few pages, the same book night after night, or even simply talking through the pictures is enough. What your baby is responding to is you.
Coming Back to Confidence
You don’t need to memorise everything.
You don’t need to be perfect.
You don’t need to second-guess every choice.
You need clear, trustworthy guidance - and the confidence to trust yourself.
Safe sleep guidance exists to support you, not replace your intuition. It offers a framework, not a judgement. Within that framework, there is space for real life, real families and real babies.
Safe sleep isn’t about fear. It’s about care. It’s about creating a space where your baby can rest safely - and where you can breathe a little easier too.
