Sleep concerns affect nearly every family at some point. When it comes to screams in their sleep, here is what the guidelines recommend.
The short answer
Babies commonly cry out, scream, or shriek during sleep without fully waking. This usually happens during transitions between sleep cycles or during active REM sleep, when the brain is highly active. It sounds alarming, but in most cases your baby is not in distress and will settle back into deeper sleep within seconds to minutes.
Key takeaways
- Babies commonly cry out, scream, or shriek during sleep without fully waking. This usually happens during transitions between sleep cycles or during active REM sleep, when the brain is highly active. It sounds alarming, but in most cases your baby is not in distress and will settle back into deeper sleep within seconds to minutes.
- Usually normal when: The scream is brief (under 1-2 minutes) and your baby settles back to sleep without intervention
- Call your doctor if: Your baby wakes screaming with a high fever, vomiting, a bulging soft spot, or extreme lethargy
- Varies by age — see the age-by-age breakdown below
“To reduce the risk of sleep-related infant deaths, the AAP recommends that infants sleep on their backs, on a firm, flat surface, without any soft bedding.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to AAP, Cleveland Clinic guidelines, babies commonly cry out, scream, or shriek during sleep without fully waking. This usually happens during transitions between sleep cycles or during active REM sleep, when the brain is highly active. It sounds alarming, but in most cases your baby is not in distress and will settle back into deeper sleep within seconds to minutes. At 0-4 months, newborns have immature sleep cycles and spend roughly half their sleep in active REM. During REM sleep, the brain is highly active, and babies may cry out, scream briefly, flail their arms, or make sudden movements without being conscious. These episodes are typically short - lasting a few seconds to a minute - and the baby returns to quiet sleep on their own. Wait a moment before intervening, because picking up a sleeping baby can actually wake them. It is generally considered normal when the scream is brief (under 1-2 minutes) and your baby settles back to sleep without intervention. However, you should contact your pediatrician promptly if your baby wakes screaming with a high fever, vomiting, a bulging soft spot, or extreme lethargy.
Normal vs. Concerning
By Age
What to expect by age
0-4 months
Newborns have immature sleep cycles and spend roughly half their sleep in active REM. During REM sleep, the brain is highly active, and babies may cry out, scream briefly, flail their arms, or make sudden movements without being conscious. These episodes are typically short - lasting a few seconds to a minute - and the baby returns to quiet sleep on their own. Wait a moment before intervening, because picking up a sleeping baby can actually wake them.
4-8 months
After the 4-month sleep maturation, babies develop more distinct sleep cycles. Brief screams during transitions between cycles are common and do not mean your baby is having a nightmare - true dreaming with emotional content is not believed to begin until around age 2. Teething discomfort or minor illness can make these partial arousals louder and more frequent.
8-12 months
Separation anxiety, learning to stand, and other developmental surges can increase partial arousals that include crying or screaming. If your baby screams, appears to still be asleep, and settles within a few minutes, this is a normal partial arousal. If your baby is fully awake and clearly upset, they may need brief reassurance before resettling.
12-36 months
Screaming during sleep in toddlers may be a partial arousal, a nightmare, or a night terror. Nightmares typically happen in the second half of the night, and your toddler will wake up frightened but can be comforted. Night terrors happen in the first third of the night - your child screams, may have eyes open, but is unresponsive and will not remember the episode. Both are common and generally outgrown.
What to Tell Your Pediatrician
- Describe when you first noticed screams in their sleep and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if screaming episodes happen multiple times per night and your baby seems overtired during the day.
- Mention if the screaming is accompanied by back arching, pulling at ears, or other signs of pain that persist when your baby wakes.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- The scream is brief (under 1-2 minutes) and your baby settles back to sleep without intervention
- Your baby does not appear to be awake during the episode and seems relaxed afterward
- Episodes are occasional and your baby sleeps well overall
- Your baby is growing well, eating normally, and developing on track during the day
- Screaming episodes happen multiple times per night and your baby seems overtired during the day
- The screaming is accompanied by back arching, pulling at ears, or other signs of pain that persist when your baby wakes
- Your baby also snores loudly or has pauses in breathing during sleep
- Your baby wakes screaming with a high fever, vomiting, a bulging soft spot, or extreme lethargy
- Screaming is accompanied by rhythmic jerking movements, stiffening, or eye rolling that could indicate a seizure
What You Can Do at Home
- Keep track of when you notice screams in their sleep — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that the scream is brief (under 1-2 minutes) and your baby settles back to sleep without intervention — this is generally within the range of normal.
- At 0-4 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Maintain a consistent bedtime routine. Keep the sleep environment cool, dark, and quiet.
- While monitoring at home, seek immediate care if your baby wakes screaming with a high fever, vomiting, a bulging soft spot, or extreme lethargy.

Related Sleep Concerns
How Long Should Baby Be Awake Between Naps?
The ideal awake time between naps (called a "wake window") increases as your baby grows. Newborns may only handle 45-90 minutes awake, while toddlers can manage 4-6 hours. Getting wake windows right is one of the most effective ways to improve nap quality, because both too-short and too-long wake times lead to poor sleep.
Is a Bath Before Bed Really Necessary?
A nightly bath is not medically necessary and some babies with sensitive skin do better with less frequent bathing. However, a warm bath can be a powerful sleep cue because the subsequent body temperature drop triggers melatonin production. If you include a bath, keep it calm and warm rather than stimulating.
How Long Should the Bedtime Routine Be?
An ideal bedtime routine for babies and toddlers is 20-30 minutes. Shorter routines may not give enough time to wind down, while routines longer than 45 minutes can become a stalling tactic. Consistency in the routine order matters more than exact length.
Is My Baby's Bedtime Too Early?
For most babies over 3 months, bedtime between 6:00-8:00 PM is appropriate. A bedtime that is too early can cause early morning wakings (before 6 AM) or long periods of wakefulness in the middle of the night. However, during nap transitions or on days when naps were short, an earlier-than-usual bedtime helps prevent overtiredness.
Is My Baby's Bedtime Too Late?
For babies over 3-4 months, consistently going to bed after 8:30-9:00 PM may result in overtiredness, which paradoxically makes it harder to fall asleep and stay asleep. Cortisol rises when babies are overtired, leading to more night wakings and early mornings. Moving bedtime earlier, even by 15-30 minutes, often improves overnight sleep quality.
Is It Dangerous for My Baby to Sleep in a Car Seat?
Babies should not be left to sleep in car seats outside of the car. Car seat-related deaths are most often caused by positional asphyxia, which occurs when a baby's head falls forward, compressing the airway. While car seats are essential and safe for travel, the AAP recommends transferring your sleeping baby to a firm, flat sleep surface as soon as you reach your destination. Never use a car seat as a substitute for a crib or bassinet.
