To help your baby sleep well, white noise is a brilliant and simple tool that works wonders. The idea is that you mimic the sound babies hear in the womb, therefore creating something familiar, comforting and reassuring. The sound is a rough, rumbly whoosh noise that is as loud as his crying. You can provide this sound simply by putting your mouth close to your baby’s ear and making a strong ‘Shhhhhhhhhhhhhhh.’  

Can You Use White Noise All Day for Babies?

As with swaddling, white noise should not be used 24 hours a day. You will want to play it at any time when your baby goes to sleep and soon he will associate it as a good sleep cue. Then, you can leave it playing all night. Make sure, however, that you don’t use a Noise Machine/Toy that has lights on it. Even a red light for the on/off switch as this can become a distraction. 

How Loud Should White Noise Be for Babies?

Louder than you might think!  Bear in mind that you are replicating the sounds in the womb – and we know that these are 20 decibels louder as a vacuum cleaner. 90 decibels is a good starting point - it’s really loud but it really works!

White noise for boys/girls

Boys respond to white noise very well. In general, boys are far more sensitive to their environment than girls and often need lots more help in blocking out the world when they are trying to sleep. If you have a little boy, white noise will be a lifesaver for you. For boys, I wouldn’t recommend a white noise toy as that will just introduce another distraction. Just use a cheap and loud Bluetooth speaker from Amazon


If you have a little girl, you’ll find that she doesn’t rely on white noise quite so much, nor will she be so easily distracted by the outside world. You could buy a White Noise toy such as the Snoo Bear from the Happiest Baby

How long should I use White Noise as a sleep aid?

White noise will be effective for at least 18 months to 2 years old. Whenever you decide to wean your baby off it, you’ll find it is very easy to do. Simply turn the volume of the machine down a notch at a time every night. Then the sound will be less noticeable and less effective until your baby will stop noticing it. Don’t wean them off it until at least 18 months as they love it!
