Your child’s brain is reading the room before bed
You can have the same bedtime routine every night—bath, books, cuddles—and still have a child who struggles to settle.
Why? Because routines alone don’t tell the brain it’s safe to sleep.
The nervous system is constantly reading the environment, and sometimes it’s the sensory cues around your child, not the routine itself, that make the biggest difference.
Sleep is a biological process that depends on many factors working together, including sleep pressure, circadian rhythm, emotional regulation, sensory processing and the environment.
Your little one’s brain is constantly taking in sensory information
We all have a sensory profile, preferring some sensations over others to help calm us and get our nervous system into a ‘rest and digest’ state.
When we understand our child’s sensory preferences, we can start creating an evening environment that feels predictable, calming and safe for their nervous system. Restful sleep can’t happen without that feeling of safety.
Supporting sensory regulation
For some children, gentle visual input can actually be regulating. This is certainly the case for my older daughter who has a preference for visual tools.
Some children require a quiet environment (less auditory input) to create an opportunity for the nervous system to transition to sleep. While this isn’t the case for my eldest (check out ASMR – she loves it!), my youngest really needs quiet time before sleep.
That’s why I’ve been enjoying using the Pococo Galaxy Projector with my girls.
Our bedtime routine hasn’t actually changed very much. We still brush teeth, read stories, cuddle and chat about our day.
What has changed is the feeling in the room.
Before, we’d move from the busyness of the evening straight into story time. Now, turning on the stars has become its own little transition. My youngest will often ask, “Can we turn the stars on?” before we choose our books, and the moment they appear across the ceiling, everything seems to slow down.

It’s become one of my favourite parts of the day—not because it makes my children sleep, but because it creates a calm, screen-free space where we can simply enjoy being together before bed.
Environmental cues matter
One of the regulating sleep systems in our body, the circadian clock, relies on cues from the environment to know where we are in the day.
Morning sunlight tells the brain it’s time to wake up and darkness helps trigger the release of sleep hormone Melatonin.
Consistent daily rhythms – what we do and when – help reinforce our body clocks.
Blue light in our environment, particularly that which comes from small screens, has been shown by research to delay sleep hormone release by hours.
Replacing bright evening lighting with low (true blue blocking) red light has a significant effect on time taken to fall asleep, as do other environmental cues that tell the brain it’s time for sleep such as cooling temperature and completion of the evening meal.
The galaxy projector has been a lovely addition here because the night time visual prompt of the dark room and ‘seeing stars’ has signalled that it’s almost time for sleep.
Once the main lights are dimmed, the stars become another gentle cue that daytime is over. We usually set the timer while we read together, so by the time stories are finished the room is already quiet, calm and ready for sleep.
It’s not replacing our bedtime routine—it has simply made those moments together feel even more immersive.
I also appreciate that it’s become a screen-free visual experience.
So many visual activities before bed involve tablets or televisions, yet we know the blue light from screens can interfere with the body’s natural preparation for sleep. Having something beautiful to look at that doesn’t involve handing over a device has been a lovely alternative in our home.
Bringing the outside world indoors
When my kids were younger I found that they were particularly fascinated by the moon, stars and night sky.
I would say things like:
“The moon is out now.”
“The stars have come to visit.”
“The birds are sleeping.”
“Our bodies are getting ready for a big rest too.”
These simple conversations help young children to begin developing an understanding of day and night and the visual cues make the concept feel more concrete.
Remember: there are many factors impacting sleep
When families come to me because their little one isn’t sleeping well, we rarely find one single cause.
We look at:
✅ Sleep pressure and age-appropriate sleep needs.
✅ Circadian rhythm.
✅ Sensory preferences.
✅ The sleep environment.
✅ Emotional regulation.
✅ Connection and co-regulation.
✅ Medical or developmental factors that may be influencing sleep.
Sometimes making the bedroom feel calmer is helpful.
Sometimes the root cause sits somewhere completely different.
The goal isn’t to buy another gadget in the hope it fixes sleep.
The goal is to thoughtfully create an environment that supports your child’s unique nervous system.
Children don’t remember whether bedtime was perfect. They remember how bedtime felt.
If your child is someone who seeks visual sensory input or enjoys talking about the moon and stars before bed, creating a calm, star-filled environment with the Pococo galaxy projector may be one small addition worth exploring. It certainly has become a special part of our evenings together.
