If your baby has trouble falling asleep or staying asleep, a white noise machine could be just the thing you need. These handy devices create a soft, consistent sound that helps block out distractions and mimics the soothing noises babies are used to from the womb. But how often should you use it? In this article, we’ll talk about the best way to incorporate white noise into your baby’s sleep routine and how to avoid overdoing it as they get older.

Why Use White Noise Machines for Babies?
Newborns and young infants can struggle to sleep in environments that are quiet or filled with sudden, jarring sounds. White noise serves as a constant auditory background, mimicking the sounds they were exposed to in the womb—such as the sound of the mother’s heartbeat or digestive system. This can make them feel more secure, helping them fall asleep faster and stay asleep longer.
Sound machines can also mask background noises in a household, such as a vacuum cleaner, siblings playing, or the noise of traffic outside. This creates a more peaceful sleep environment that reduces the likelihood of waking up due to unexpected sounds. For babies who have difficulty settling, white noise may be the perfect solution to improve their sleep quality.
How Often Should You Use White Noise Machines?
The frequency with which you use a white noise machine will depend on your baby’s individual sleep needs, as well as the broader sleep environment. There is no one-size-fits-all answer, but there are some general guidelines that can help you decide when and how to incorporate it into your baby’s routine.
Daily Use for Consistency
Most parents find that using white noise machines works best. Babies thrive on routine, and consistent use of white noise can signal to them that it’s time to sleep. By playing a soft, constant sound during both naps and nighttime sleep, babies start to associate that noise with sleep, making it easier for them to wind down.
If your baby has trouble falling asleep or staying asleep due to household noise or if they are easily startled, white noise machines are especially helpful throughout the day. For some babies, turning on the sound machine right before naps or bedtime helps signal the transition into sleep time, which can make falling asleep easier.
Timing the White Noise During Sleep Cycles
When babies sleep, they go through different sleep cycles. These cycles typically last 45 minutes to an hour in the early months. Babies will often wake up briefly between sleep cycles, especially if their sleep environment changes—like if the white noise stops. If your baby has become accustomed to the white noise machine, sudden silence can disrupt their sleep. Keeping the white noise on throughout the night or during naps might help them return to sleep on their own after these brief awakenings.
However, if you’re planning to use a timer or turn off the sound machine after a certain period, it’s important to consider how your baby reacts. Some babies might not need white noise to fall back asleep between cycles, while others could become unsettled if it stops unexpectedly. It’s often best to let the machine run the entire time until your baby has developed a more predictable sleep cycle.
As Needed for Sleep Troubles
Not every baby requires white noise to sleep. If your baby sleeps soundly without it, there’s no need to use a sound machine just for the sake of it. On the other hand, if your baby struggles with colic, frequent waking, or short sleep cycles, white noise might help them settle more easily. In cases where sleep is a challenge, using a white noise machine regularly can help create a more stable and restful sleep environment.
In some cases, white noise may not work immediately. If you’re using it for the first time or have recently adjusted the volume or sound type, it could take a few days for your baby to get used to it. During this adjustment period, try keeping the machine on during every nap and overnight sleep, but don’t be discouraged if it doesn’t seem to help right away.
Avoid Overuse and Dependency
While white noise can be an effective tool for promoting better sleep, it’s important not to rely on it too much, especially as your baby gets older. There’s a potential downside to making the sound machine a necessary part of every nap and nighttime sleep routine.
Over time, babies can become dependent on white noise to fall asleep. This can create challenges if you’re traveling or if your baby is staying somewhere where a sound machine isn’t available. If your baby becomes used to falling asleep only when the machine is on, it might be harder for them to transition to sleeping without it. To prevent this, it’s a good idea to start weaning your baby off white noise gradually as they reach an appropriate age (typically between 18 months and 2 years old). This doesn’t mean abruptly stopping the white noise, but rather gradually reducing the volume or frequency with which it is used.
Safety Guidelines for Using White Noise Machines
While white noise machines are generally safe for babies, it’s crucial to use them properly to avoid potential risks. The American Academy of Pediatrics (AAP) has provided some clear safety recommendations for using sound machines around infants:
• Keep the volume low. The AAP recommends keeping the volume no higher than 50 decibels, which is about the level of a quiet dishwasher. Exposure to higher volumes can damage your baby’s delicate hearing.
• Positioning. Place the machine at least 7 feet away from the crib to minimize the risk of hearing damage. Avoid placing it directly next to the baby’s sleep space.
• Continuous noise. White noise should be used to create a consistent auditory environment, but avoid making it loud enough to cause discomfort. The goal is to create a soothing background sound, not to drown out all other noises.
White noise can be a game changer for helping your baby sleep, especially if they’re sensitive to noise or have trouble settling down. Using it every night and during naps can help create a peaceful sleep environment. Just be careful not to make it a crutch—it’s important to gradually reduce its use as your baby gets older and learns to sleep without it. With these tips, you can help your little one sleep soundly while keeping their hearing safe and sound.
FAQs
Can white noise damage my baby’s ears?
White noise can damage hearing if the volume is too high or if the machine is placed too close to the baby. Follow the recommended volume limit of 50 decibels and keep the machine at least seven feet away from the crib.
When should you start using white noise?
White noise can be used from birth to help babies sleep. It mimics womb sounds and helps babies feel secure in their sleep environment.
Can I stop using white noise once my baby is older?
Some parents stop using white noise around age two, while others continue until their child is three to four years old. The decision should be based on whether your child still finds it helpful.
