When you become a parent, you’ll realize that baby’s sleep becomes one of the biggest challenges for you, bringing with it the questions such as whether your baby is getting enough sleep, should they be napping more and wondering if it’s normal for them to wake every two hours.
Here at Zello, our mission is to support families with sleep solutions that actually work. Our baby white noise machines have been expertly designed and have helped thousands of parents settle their little ones.
Our aim in this guide is to break down how much sleep your baby really needs at each stage. We’ll also give you practical tips, including how white noise, pink noise and natural sounds can help.

Newborn to 1 Month: 16–18 Hours of Sleep
Newborns spend most of their time asleep but not in long stretches. They will tend to sleep for 2-3 hours at a time, only waking for a feed. Newborn babies may sleep for up to 18 hours over a 24 hour period, with no clear distinction between night and day. Their circadian rhythm hasn’t developed yet so you’re likely to be up at all hours and that’s why it’s hard.
During this time of unpredictable sleep, a Zello White Noise Machine can be very helpful. A sound machine can mimic the constant sounds of the womb, with brown noise focussing on heartbeat sounds or gentle whooshing. These familiar frequencies help calm newborns, reduce crying, and promote longer stretches of sleep.

1–2 Months: 15.5 to 17 Hours of Sleep
Between these months your baby is still sleeping a lot, but wake windows are slowly lengthening. Sleep remains fragmented, and most babies aren’t sleeping through the night yet.
Begin introducing a simple sleep routine with a feed, cuddle and gentle rock. Then play soft white noise in the background to signal to baby that it’s time to wind down.
The best sounds for this age are gentle shushing sounds, pink noise or natural ambient noise like rain or waves, creating a calming and sleep-friendly space.

3–4 Months: Sleep Regression Territory (14–16 Hours of Sleep)
This is a major developmental phase when your baby’s brain is growing rapidly and sleep may temporarily regress. Night waking and shorter naps are common and baby is also learning to distinguish day from night - a big step forward!
Stick to a consistent bedtime routine and create a familiar sleep environment. The white noise sound machine now becomes an essential part of this phase as it acts as a cue to sleep and blocks household noise that can wake a light sleeper.
Select white noise or fan sounds that play continuously to help babies link sleep cycles and avoid frequent waking.

5–6 Months: Longer Night Sleep (13–14.5 Hours of Sleep)
By now, many babies are ready for more structured routines. Night time stretches may be longer, around 6-8 hours, and they usually nap two or three times a day.
At this stage it is the perfect time to reinforce healthy sleep habits with consistent naps. Baby will understand that a dark room and your trusty baby sleep machine signals bedtime. Play soothing pink noise, a deeper, smoother alternative to traditional white noise.

7–8 Months: Self-Soothing and Routine Building (13–14 Hours)
Babies are now learning to self-settle and may be able to sleep independently with gentle guidance and a couple of naps a day is typical.
Pro tip: If your baby is easily disturbed by everyday household sounds, a white noise machine can make a big difference. It will mask background noise like siblings, traffic, pets, or phones, allowing for a peaceful, uninterrupted sleep.
For middle of the night check-ins, Zello’s machine is perfect, with its volume control and soft-glow lighting,

9–10 Months: Predictable Sleep Patterns (Around 14 Hours)
Your baby’s sleep becomes more predictable with solid routines. Two naps per day are still common.
Be mindful that teething, illness or separation anxiety can all affect sleep at this age so it’s important to maintain familiar sleep cues like your sound machine, a bedtime story, and cuddles. These will all help baby feel secure.
Recommended noise options would include brown noise or heartbeat-style audio, a soothing, low frequency sound to encourage deep rest.

11–12 Months: Toddlerhood Incoming (13–14 Hours)
Many babies drop to one nap by the end of this phase, although some do still stick to two. They're becoming more active during the day and may fight sleep at bedtime.
Even if your baby’s sleep is more consistent, white noise still matters. A baby white noise machine will keep their sleep environment calm and they will understand it is part of their routine. This consistency is especially helpful during travel, teething, or nap transitions.
Our portable sound machines are ideal for travel cots, prams, or hotel rooms, so baby can always have their familiar sleep sound wherever they are.

Why Use a White Noise Machine?
White noise isn’t just trendy and the current new “must-have” item. It is backed by science. Babies are born into a world that is actually much quieter than the womb so the gentle hum of white noise, pink noise, or brown noise mimics the sounds they heard when growing inside mum, helping them relax and sleep longer.
Benefits of using a sound machine for baby sleep:
-
Improves sleep quality by helping babies fall asleep faster
-
Helps babies link sleep cycles and stay asleep longer
-
Masks disruptive noise like doors, dogs, or siblings
-
Creates a consistent sleep cue as part of a bedtime routine
-
Can reduce stress for both babies and their exhausted parents
