The pattern that started it all

Does the reflective design come off?

No. The pattern is woven in with a patent-pending, no-shed process, not a print or a sticker. It stays put wash after wash, and it’s certified safe against baby’s skin.

  • Durable, no-shed reflective weave
  • Machine-washable, dries fast
  • Reflective on front and back

Why this matters

Sleep shapes maternal mental health.

An easy glance at the monitor isn’t just reassuring, the link between sleep and postpartum wellbeing is well documented in the research.

Perinatal depression is the most common obstetric complication in the United States, and addressing sleep problems may help improve maternal mental health.
Mothers with postpartum depression showed poorer sleep quality and lower sleep efficiency; improving sleep can reduce the severity of depressive symptoms.
Postpartum sleep has a significant impact on maternal and infant outcomes, and is tied to a range of clinical factors.

Findings summarized from published research by these institutions. PeekaSleep is sleepwear that makes your baby easier to see, not a medical device or treatment.

Good questions, honest answers

Before you reserve yours

On a night-vision camera that can see the crib, the reflective pattern shows up as bright points that move with every breath. It shows best with the camera above the crib, pointed down, night vision on, and the lights off. If your camera sits on a dresser or the wall beside the crib, the pattern shows less. Try it for 30 nights, if you can’t see it on your camera, send it back.
No. PeekaSleep is sleepwear that makes your baby’s movement easier to see, it doesn’t track vitals, sound alarms, or replace safe-sleep guidance. You stay in control of what you’re watching.
It’s woven into the fabric, not applied on top, and the whole garment is OEKO-TEX® Standard 100 certified, independently tested for harmful substances. Nothing sheds, nothing irritates.
Send it back within 30 nights for a full refund. If PeekaSleep doesn’t give you more restful nights, you shouldn’t pay for it.
Go by your baby’s weight and height for the age ranges shown. Sleep sacks should be snug at the shoulders and roomy at the legs, when in doubt, size to their current weight.

30 nights to sleep easier, or your money back

We built PeekaSleep for the 2am glance at the monitor. Try it for 30 nights. If it doesn’t bring you the calm we promise, we’ll refund every cent and cover the return.

Tonight, you could actually rest.

Peace of mind

This has given me so much peace of mind and I can finally sleep at night. No more 3× zoom on the monitor, holding my breath to see if baby is breathing. I love that the reflective pattern is on both front and back, so I can even see when he’s on his tummy!

Comforting and comfortable

I purchased this for my new nephew who was born very early. His parents are justifiably anxious about his breathing, and even with the O2 monitor from the hospital, this extra level of reassurance has been great for them.

No more creeping in to check

No more creeping into his room to check if he’s breathing. I just glance at the monitor and watch the reflective pattern rise and fall.

Better than the Owlet

Got this instead of an Owlet. It works better, and no false alarms at 3am.

NICU-friendly reassurance

NICU said no Owlet. This is way better, nothing worn on the baby, and I can still see every movement on the monitor.

Works with my camera

Worked on my Amazon Babysense camera. Just keep the room dark and the pattern lights right up.

Still soft after months

6 months and many washes later, it’s still soft & reflective. Zero peeling.

Love the zipper

Surprisingly 5-star soft, and the bottom-opening zipper is so helpful for middle-of-the-night changes.
