Baby Sleeping With Eyes Open: Normal or Worth Asking?
A baby sleeping with her eyes half open, or with a slit of white showing under the lids, is usually not a problem. Newborns spend a big share of their sleep in active (REM) sleep, which the AAP describes as the stage where “her eyes move under her closed eyelids” while she twitches and breathes irregularly. Lids that flutter or don’t quite meet are part of that busy stage. Sleeping with the eyes partly open also happens in adults; Cleveland Clinic says “about 20% of people sleep with their eyes open.” It’s worth asking your pediatrician if the eyes are red, watery or look dry after sleep, if one eye never closes even when she’s awake or crying, or if one side of her face moves less than the other.
What you’re actually seeing
The first time is unsettling. You look into the bassinet and she’s asleep, breathing, limp-armed, with her eyes open a crack. Sometimes you can see her eyes rolling or flicking behind the lids. It looks like she’s watching you. She isn’t.
The AAP explains how newborn sleep is built. Newborn sleep “is about equally divided between rapid eye movement (REM) and non-REM sleep.” In REM, which it also calls active sleep, “the baby may twitch or jerk her arms or legs, and her eyes move under her closed eyelids.” Breathing is irregular in this stage too. In deep, quiet sleep, “twitching and other movements cease.”
So a baby with moving eyes, a slightly open lid, twitches and uneven breathing is very likely in active sleep. Betteroo’s guide on how to tell a stirring baby from a waking one lists “eyelids that flutter or briefly open” among the normal signs. It contrasts them with the “wide, focused, tracking eyes” of a baby who is actually waking up.
The same busy stage explains the other things that worry you at 2am: the fast, uneven breathing and the sudden startles.
Is it normal for a baby to sleep with eyes open?
Usually, yes. There are two honest parts to that answer.
The reassuring part. Lids that don’t quite close during sleep are common in people generally. Cleveland Clinic calls it nocturnal lagophthalmos, where “your eyes close normally when you’re awake but not when you’re asleep.” It also notes the gap is often “quite small,” small enough that it can go unnoticed.
The part I won’t overstate. I couldn’t find a pediatric source that gives a figure for how many babies do this, so I won’t give you one. What matters more than a number is the pattern. A baby whose eyes close fully when she’s awake and blinks normally, whose eyes look clear and comfortable when she wakes, and who sleeps with a sliver of white showing is in very different territory from a baby with a red or weepy eye.
Why her eyes look like they’re rolling back
This is the part that sends people to Google at 2am. A sleeping baby’s eyes can drift up and move around under half-open lids, so you see more white than you expect. In active sleep, the eyes move by design. That’s what the “rapid eye movement” in REM means.
Everything in this post is about a baby who is asleep. If something about her eyes or movements worries you while she’s awake, or she doesn’t respond to you the way she usually does, that’s a different question and a call to the pediatrician. Take a short video if you safely can, so the doctor can see what you saw.
Should I close her eyes or wake her?
There’s no need to close them. Touching her lids may well wake her. Let her sleep.
Waking her just because her eyes are open will usually cost you the nap. The AAP says babies in deep, quiet sleep “may be more difficult to awake.” Active sleep is lighter, and lighter sleep is easier to break. A “baby is awake” glance at half-open eyes is exactly how many of us pick up a sleeping baby and get a wide-awake one. If she wakes every time you put her down, it’s worth knowing that open eyes don’t always mean she’s awake.
The safe-sleep basics don’t change. She goes down on her back, in a bassinet or crib with only a fitted sheet, as the NIH’s Safe to Sleep guidance describes.
When it’s worth asking the pediatrician
Cleveland Clinic lists the signs that eyelids not closing properly is causing a problem: eyes that “water or are dry,” “red eyes,” photophobia (sensitivity to light), and the feeling of something in the eye. Those happen because the surface of the eye dries out at night. In a baby, you can’t ask about grit or burning, so look for what you can see:
- Red or bloodshot eyes after sleep, especially in the same eye every time
- A watery or crusty eye, or a baby who rubs at one eye or turns away from light
- One eye that never closes, even when she’s awake, crying or feeding
- One side of her face moving less. MedlinePlus, from the US National Library of Medicine, says a facial nerve injury at birth can mean the “eyelid may not close on affected side” and the mouth doesn’t move the same way on both sides when she cries. It says to make an appointment if you notice that.
- A cloudy or hazy-looking eye. That needs a pediatrician or eye doctor regardless of how she sleeps.
A crusty, watery eye on its own is very often a different, common thing. Blocked tear duct in babies explains how to tell.
| What you’re seeing | What to do |
|---|---|
| Eyes half open or rolling during sleep, twitching, uneven breathing | Normal active sleep. Let her sleep |
| Lids don’t fully close in sleep; eyes clear and comfortable on waking | Mention it at the next checkup if it bothers you |
| Red, watery or crusty eye after sleep | Call the pediatrician |
| An eye that doesn’t close fully even when awake or crying | Call the pediatrician |
| One side of the face moves less when she cries | Make an appointment |
| Cloudy eye, or squinting away from light | Call; ask about an eye doctor |
| Anything about her eyes or movements that worries you while she’s awake | Call; video it if you safely can |
You’ll read about adult treatments for nocturnal lagophthalmos, like eye drops at night or taping the lids. Those are adult treatments. Don’t put anything in or on a baby’s eyes unless her pediatrician has told you to.
FAQ: baby sleeping with eyes open
Why does my baby sleep with her eyes half open?
Most often because she’s in active (REM) sleep, when the eyes move under the lids and the lids may flutter or part slightly. The AAP says newborn sleep is about half REM.
Is it bad for a baby to sleep with eyes open?
Usually not. It’s worth asking the pediatrician if her eyes look red, watery or dry after sleep, or if an eye doesn’t close even when she’s awake.
Should I close my baby’s eyes while she sleeps?
No need. Touching her lids may wake her. If her eyes look comfortable and clear when she wakes, leave them be.
Do babies grow out of sleeping with their eyes open?
The AAP notes that newborn sleep patterns differ from those of older children, with about half of a newborn’s sleep spent in REM. If an eye still doesn’t close fully as she grows, or looks irritated, ask her pediatrician.
Can a baby see when sleeping with eyes open?
No. Cleveland Clinic explains that when people sleep with their eyes open, they don’t actually see anything, because the brain has “taken that function offline.”
