Sleep's Dynamic Duo -  White Noise and A Nightlight

Sleep's Dynamic Duo - White Noise and A Nightlight

Posted by Laura Klein on 7th Oct 2018

Good sleep is the cornerstone of a happy child and a happy family.  There is no "best method" of creating a bedtime routine - each family finds a consistent method that suits them and their child.  

However, there are 2 tricks to setting up the sleeping area to optimise a calm, consistent and comforting environment.

We are talking about 'white noise' and a 'nightlight'.

Let's explore those ideas a little more....

White Noise

It's a fact supported by sleep consultantsresearchers and paediatricians around the world, including Dr Harvey Karp - babies and young children sleep better with white noise! 

White noise is hands down the most effective, easiest to implement, inexpensive sleep aid for babies. And there's good science to support this claim.

Sophie from Sleep, Play, Love explains that babies have just spent their entire life in the womb. And the womb is surprisingly and deafeningly loud - heartbeats, blood pumping, fluid swishing and even the sounds of the outside world like music and voices. In fact, the volume is around 50 decibels, just slightly less than a lawnmower. They are so used to this hum, that it makes sense to replicate that from the day they are born!

Fast forward to toddler years, and the last thing any parent wants is a sleeping child awoken by a noisy neighbour, an early morning garbage truck, or birds that chirp at dawn.

‘White noise ’ can be in the form of any low frequency, consistent hum (think rainfall, ocean, wind whistling, oscillating fan) and can have a huge impact on positive sleep behaviours. You’ve probably heard your great aunt’s story about how her babies slept straight through while she vacuumed under the cot - and she was right! Best of all, with the right machine, it's an environment you can easily create for your little one. It doesn't require Mum or Dad to be right there to keep it going. The right white noise machine will play for the duration of the day and night time sleep.

Here are 6 great reasons why white noise is a magic thing for sleep...

1. White Noise Reduces Stress in Babies

What do babies get stressed about? Just about everything. They’re stressed when they’re over-tired, they’re stressed because their world is more stimulating than they’re ready to handle, they’re overwhelmed with lights, faces, and excitement. White noise creates a safe space for them by blocking out that stimulation.

2. White Noise helps Babies Sleep.

They fall asleep more easily and stay asleep longer. Babies experience “sleep transitions”, usually about every 20-45 minutes. Ever wonder why your baby only naps for 20 minutes at a time? Well it’s because when she hits her sleep transition at the 20 minute mark she is unable to fall back into deeper sleep and thus her nap is over. White noise helps babies gently navigate these transitions to get longer, more restorative naps. It also helps to block out the noise of life (older siblings, doorbells, garbage trucks, etc.) that can interfere with naps and night sleep.

3. White Noise Helps Babies Cry Less

Did you know that shushing is a sound that people universally understand and make with babies? Shushing is simply white noise that you make yourself. The key to using white noise to help calm a crying baby is that it needs to be LOUDER than the crying. Holding a screaming baby while shushing like a gentle librarian is useless. Your baby can’t hear the shushing over his own crying. You need to shush LOUDLY so that the calming noise can penetrate above the crying and you may need to shush for a while. Loud sustained shushing can be a challenge, not to mention exhausting for parents. If you’re starting to feel dizzy, it’s time to outsource your shushing to an electric white noise device, that will play continuously without you.

4. White Noise Reduces the Risk of SIDS

A landmark study showed that babies had a significant reduction in the risk of SIDS if they had a fan in their room. Nobody knows why the fan helps – it could be my moving the air around although many believe it has to do with the white noise the fan makes. We do know that white noise reduces active sleep (which is the sleep state where SIDS is most likely to occur).

5. White Noise is Easy to Wean Off

Many parents say they don’t want to use white noise because they are afraid their baby will become addicted. However, this is rarely the case. When your baby is older (generally after their 1st birthday) you can gradually start to decrease the volume of the white noise, if desired. If they continue to sleep well, you’re done. If they wake up more frequently then turn the white noise back on. Plenty of toddlers and older children continue to find comfort and deep sleep by using white noise into late childhood - and as it's an independent sleep aid, it's such an easy thing for parents to set and forget.

6. It Will Help Parents Sleep Better Too

If you're sleeping in the same room as baby, you'll probably sleep better too! It'll help drown out baby's loud noises so you stop waking to every little sound he makes (grunts, gurgles, farts, squeaks and more!) Furthermore, if you stop waking to every little sleep sound, you'll also stop trying to feed or comfort baby with every little noise he makes. Plus, many of you will notice, even if you've never slept with it before, that white noise is really soothing for you too.. You'll probably miss it when baby moves out of your room and takes it with him!

Did you know Brown Noise is actually the lower frequency cousin to white noise - and is actually preferred by babies? Hush Vaporiser Kit has built in brown noise, which is similar to a deep thunder rumble. Perfect for sleep and relaxation. 


Healthy sleep patterns are a complex issue.  Many parents worry that a night light may make their little one restless and interrupt sleep. We believe a dim nightlight can provide a soothing ambiance that will help lull their little one off to sleep at bedtime and help them get back to sleep if they wake during the night.

Baby sleep is not like toddler/older child sleep. Babies usually aren't afraid of the dark. In fact, they just spent many months sleeping in your womb where it was pretty dark. However, many parents find that a nightlight provides a calming atmosphere when their baby wakes during the night and that the light makes it easier for them to check on baby as they sleep. If you do choose to use a baby nightlight consider these suggestions:

  • Position the light slightly away or lower than the cot so it will not shine directly in your baby’s face.
  • Make sure that it is a very dim light emitting just enough light so you can see them sleeping and not enough to fully wake them when they stir.
  • Select a 'warm' colour (red, pink, orange) rather than a 'cool' colour (blue, green, white) to maximise melotonin production.

In the toddler years, and beyond, children can experience fear of the dark or being alone at bedtime and find great comfort in a nightlight near their bedside each night.  It is particularly helpful if they wake in the night and can't find their toy or blanket, or need to get up to go the toilet. A warm colour light is still recommended however many children have a preference for a 'favourite' colour.

A Bonus Tip....

We all love a little bit more, so another idea that can have a positive effect on deep sleep from birth is swaddling. Babies and toddlers are little houdinis and can unwrap themselves from traditional swaddles, so choosing a smart design, modern sleep swaddle is essential. 

The team at SLEEPY BUB have transformed traditional swaddles for babies by using the latest innovation of zip-down arms. Ancient cultures used a similar arms down swaddling technique for centuries. Goodbye messy blankets and unwrapped arms, hello safe and secure sleep time.

I hope these ideas have given you the incentive to try the magic of white noise, nightlights and swaddles for yourself. 

We have a brilliant bundle containing Hush - our newest sleep vaporiser which is a combo of mist vapour, red light and built in sound - including brown noise.

PS: If you have a particularly fussy baby or are looking for ways to survive the dreaded witching hours, you may want to bring your white noise maker out into living room (or wherever you like to grind through the fussy part of the day) to help create a calming environment for your fussy baby. Simply move it back when it’s time to sleep. Good luck!

Much love,
