Getting babies to sleep is almost like rocket science, no one has an exact formula on how to get them to sleep. And if you are wondering do light projectors help babies sleep, we have an answer for you.
If you search for a night light projector or night light for babies on Amazon, you will get hundreds of options to choose from. All manufacturers are claiming it to be asleep soother for babies, but science proves them wrong.
New parents buy cute nightlight projectors with sounds and music in hope that they will help their baby slumber restfully, but it may actually be a reason for difficult bedtimes and their frequent night waking.
When I brought my newborn from the hospital, he wouldn’t go to sleep at night. it took all most three months to show day-night rhythms. Even after three months, he would frequently wake up at night. At that point, following the advice of a friend, I considered buying a nightlight projector with built-in white noise, music, and a starlight show.
But to my surprise, it did not work. After doing a little bit of research, I found that any kind of light – light show or dim night light, can have a tremendous effect on your baby’s sleep.
And if you are considering buying night light projectors to help your baby sleep, you need to read this article.

Do Light Projectors help Babies Sleep?
There are many nightlight projectors available in the market in the form of cute characters, plush animals, or other forms to make your nursery look pretty. Also, they are loaded with so many features like in-built lullabies, music, white noise, and light projections in all the colors of the rainbow.
They are pretty attractive and advertised as sleep soother for babies, but in reality, it adds to the problem.
Bright light exposure at bedtime can have an adverse effect on a baby’s sleep, did you know that?
This is because the wavelength of different colors of lights can have an adverse effect on your child’s sleep biology. Light at night is a signal to the brain to delay the onset of sleepiness in babies.
Scientist has known for the longest time that white and blue (green) based lights exposure at bedtime, inhibit child’s melatonin at night. Melatonin is the sleep hormone released by the brain in response to light exposure at night. This hormone is not only necessary for your baby to go to sleep, but to stay asleep at night.
But when they are exposed to nursery light – white, blue, green, or purple, even when lit dim, can disrupt your baby’s sleep. The wavelength of lights in the range of 460-480, maybe good at re-setting the body’s internal clock to a later schedule.
Most nightlight projectors emit lights of shorter wavelength, which appears blue to our eyes. Studies have found that shorter wavelength light has a significantly larger effect on melatonin and circadian rhythm than light with a larger wavelength (1,2). And neurons in our retina respond maximally to blue light and gives a signal to the brain to stay alert, even when lit dim, by inhibiting the production of melatonin.
Even though the blue color is regarded as ‘calming’, it may not be as calming when it comes to night-time slumber.
Using nightlight projectors at bedtime is similar to exposing your kids to TVs, laptops, smartphones before bedtime. Blue light emitted from these devices can send a message to the brain to be alert even at nighttime (3).
So, sleep experts recommend turning electronic devices off one hour before a child’s bedtime to allow their body to start producing melatonin.
This explanation may clarify why light projectors do not help babies sleep.
But that leaves us with a question,
Should my baby room be Pitch Black?
Ideally, babies should sleep in the pitch black. Darkness allows the production of melatonin and provides distraction-free sleep for your baby. In fact, if you take your overtired or overstimulated baby in a dark room and try to soothe them, they are more likely to calm down.
Actually, babies do not need light and any kind of night light can be stimulating for them to fall asleep or staying asleep. Some babies are really distracted by night lights and have a hard time falling asleep. Specifically, night lights projectors that turn light on and off or changes colors of lights can be extra distracting for babies.
But if you need a light in your baby’s room for night feeds and diaper change, opt for a red night light. The red night light is not overstimulating for your baby. Some parents also keep the door of the baby’s nursery opens a bit to use the light from the hallway for night feed or diaper change.
How Dark Should my Baby’s Room be at Night?
Your baby’s room doesn’t have to be pitch dark if you don’t want it to be. You can use a red plug-in night light in your baby’s nursery. You can keep it on all night. If you find night light to be too bright, hide it behind the furniture to avoid your baby’s exposure to too much light.
What color of Night Light is best for Baby Sleep?
Virtually all artificial lights can affect your baby’s sleep but not all types of lights have the same impact. Red based light has a much higher wavelength than the other color light.
According to research studies, red light does not affect the internal clock of melatonin production (4). Although it does not improve your baby’s sleep, it does not inhibit melatonin production like blue light does. Red light is not too stimulating for your baby and allows enough visibility for night feeds and diaper change.

Tips to Reduce Blue Light before Bedtime and at Nighttime
Exposure to blue light can ruin your baby’s nighttime slumber. There are several things that you can do to minimize the exposure to blue light before and at nighttime. Here are a few tips to keep in mind.
- Do not use night light projectors, instead use night lights that are red or orange. Red light is less stimulating for your baby and yet gives you enough visibility for midnight feeds and diaper changes
- Do not use light at all in the nursery. Keep a nursery door crack open to get light from the hallway for feeds and diaper change
- Avoid using energy-efficient (blue) bulbs even in the washroom.
- Minimize your baby’s exposure to bright light before an hour before bedtime.
- Use battery-operated candle lights in the washroom for baby bath time before bed and for other bedtime rituals like massage or feeding.
Can 1-year Old be Afraid of Dark?
If your 1-year old is upset at night, it is not because he is afraid of the dark. This is because they are not developmentally capable of being afraid of the dark. They have spent 10 months in darkness in the womb, so they are okay with the darkness.
Actually, darkness is soothing for them.
At the age of 1 year old, they are more aware of separation from you. So if they are fussing in their room, is most probably due to separation anxiety and because of the darkness.
At What age Babies start being afraid of the Dark?
As mentioned earlier babies are not afraid of dark almost until they are around 2 years of age. Fear of the dark usually appears when toddlers are 2 years old and lasts until their preschool years or even longer.
As your baby grows, you may need a night light in their room if they are afraid of the dark. Separation anxiety along with natural nighttime fear may make your child feel anxious at night.
A night light projector or a night light can be helpful in providing reassurance and comfort to your toddler in the middle of the night if they are afraid of the dark.
You can manage without a night light with the babies but if your 2-year old is suddenly afraid of the dark, do not hesitate to try one.
