Do Babies Need Blackout Curtains?


As any new parent knows, creating a perfect sleep environment for your little one is paramount.

We’re willing to try anything to achieve those precious uninterrupted hours.

One popular sleep aid gaining traction is blackout curtains. But do babies need them?

Quick Answer

The short answer is yes, babies generally benefit from a dark sleep environment. But there’s more to it than just flipping a switch.

Why Darkness Matters for Sleep

Newborns are born with immature circadian rhythms, the internal clock that regulates sleep and wake cycles.

As they develop, exposure to light and darkness plays a vital role in setting and synchronizing this rhythm.

Darkness triggers the production of melatonin, a sleep hormone, while light suppresses it.

This is why a dark environment promotes deeper, more restful sleep for both babies and adults.

Why Blackout Curtains Might Be Beneficial for Babies:

While not every baby will be a blackout curtain devotee, there are several potential benefits to consider:

Promotes Deeper Sleep

Darkness triggers the production of melatonin, the sleep hormone.

Blackout curtains block out sunlight and artificial light, creating a darker environment that helps babies fall asleep faster and sleep more soundly.

This deeper sleep can be crucial for their development, as it supports brain growth, hormone regulation, and overall health.

Regulates Sleep-Wake Cycles

Consistent light exposure plays a vital role in regulating circadian rhythms, the internal clock that tells our bodies when to sleep and wake.

Blackout curtains can help establish and maintain a regular sleep schedule, especially in areas with early sunrises or late sunsets.

This can lead to better daytime mood, less crying, and improved overall well-being.

Improves Daytime Naps

Ensuring quality naps is crucial for babies’ development.

Blackout curtains can block out light during the day, creating a dark environment conducive for napping.

This can help babies sleep longer and wake up more refreshed, leading to better nighttime sleep as well.

Blocks Distractions and Noise

Blackout curtains can also block out external distractions, such as streetlights, car headlights, or noise from outside.

This can create a calmer and more peaceful environment, allowing your baby to fall asleep and stay asleep more easily.

Provides Privacy and Security

Blackout curtains offer an extra layer of privacy, shielding your baby from curious onlookers and creating a secure haven for them to sleep.

Developmental Stages and Blackout Curtains

A baby’s need for darkness evolves as it develops:

Newborns (0-3 months):

Newborns are relatively insensitive to light and primarily sleep based on internal cues. Blackout curtains may not be essential at this stage, but consistent sleep routines are crucial.

3-6 months:

As melatonin production increases, babies become more sensitive to light. Blackout curtains can help extend naps and improve nighttime sleep.

6 months – 1 year:

This is when circadian rhythm development kicks in. While blackout curtains can still be beneficial for naps and nighttime sleep, introduce some morning sunlight to regulate the internal clock.

Toddlers (1-3 years):

The need for darkness persists, but toddlers may become more curious about light and darkness. Blackout curtains can provide a comforting sleep environment while allowing occasional light exposure during the day.


Ultimately, the decision of whether to use blackout curtains is a personal one.

If you live in a bright area or your baby is a light sleeper, blackout curtains can be a valuable investment in their sleep health.

If you’re unsure about blackout curtains, you can start with a portable blackout shade or tent for your baby’s crib.

This is a more affordable option and can be easily removed when you’re no longer sure about its necessity.


When should I start using blackout curtains for my baby?

You can start using blackout curtains as early as you like, even in the newborn stage.

Is it okay to use blackout curtains all day long?

It’s generally not recommended to use blackout curtains all day long, as some exposure to sunlight is important for vitamin D synthesis and regulating their circadian rhythm.

Do blackout curtains block out noise?

While not their primary function, some blackout curtains with thicker fabrics can help reduce noise levels in the nursery.
