Do Babies Dream?

Do Babies Dream?

As new parents gaze at their sleeping newborn, often the question arises – what’s going on in that little head? While we can only speculate about infant dreams, research provides intriguing clues into the mysterious dream world of babies.

Understanding what science reveals about early cognitive development and sleep cycles gives insight into babies’ nighttime mental experiences. While more questions than answers remain, peering into the dreaming minds of babies invites wonder about how they perceive and process their brand new world.

Why Babies’ Dreams Are a Mystery

The question of babies’ dreaming brings many unknowns for several reasons:


Since infants can’t yet describe dreams in words, we rely solely on outward behaviors and cues.

Undeveloped Memories

Lacking a large store of experiences and concepts, baby dreams likely differ vastly from the complex narratives and scenarios of adults.

Primitive Cognitive Pathways

Babies navigate the world through primal sensory perceptions. Internal reflections remain simple with limited reasoning abilities.

Immature Sleep Patterns

REM cycles mature rapidly over the first years. Time spent in dream-state REM expands as sleep architecture develops.

While much remains mysterious without verbal confirmation, mounting research continues yielding intriguing clues into early dream activity.

Do Babies Dream in the Womb?

Dreaming likely starts earlier than you may imagine. Some fascinating observations point to dreaming beginning in the third trimester while still in the womb.

Signs of REM Sleep In Utero

Brain wave tracking indicates babies enter REM sleep cycles by about week 30 of gestation. REM is when vivid dreaming occurs.

Observable Physical Reactions

4D ultrasound scans reveal unborn babies actively moving their eyes, mouths and faces during REM cycles while floating in amniotic fluid – reactions associated with dreaming.

Exposure to Sights and Sounds

Studies show fetuses process and remember stimulation from lights, voices and music experienced in late-stage pregnancy. These perceptions fuel dream content.

Learning During Sleep

Sleep studies demonstrate third-trimester babies dreaming about practiced skills like thumb-sucking observed in utero, aiding memory development.

So while we can’t know the actual dreamscape of slumbering babies in the womb, compelling clues strongly suggest rich inner lives taking shape before birth.

How Much do Newborns Dream?

Newborns spend an astounding 80% of sleep time in the REM dream stage. But their sleep cycles are quite short, only about 50 minutes long with brief 5-10 minute REM portions. This translates to:

  • Newborns dreaming about 2 hours divided over 8sleep cycles daily.
  • Dream times are concentrated in early morning hours when REM cycles are longest.
  • Dreaming happens in shorter bursts of a few minutes at a time.
  • Overall sleep time averages 15-17 hours for newborns, aided by frequent daytime napping.

While newborns dream frequently, their dreams are fleeting. As sleep cycles mature over the first year, REM phases elongate allowing lengthier, more complex dreams.

What Do Babies Dream About?

With limited life experience, what fills the dreaming minds of babies? Some potential themes include:

Faces of Parents and Caregivers

The sound of voices and facial expressions observed during babes’ waking hours stimulate dreams. Familiar faces likely appear often.

Breast or Bottle Feeding

Drinking milk is one of an infant’s earliest gratifying experiences. Feeding sensations may replay during sleep. Sucking motions are observable.

Floating and Rocking Motions

The vestibular stimulation of motions from strollers, car rides and parents pacing with a baby may translate into dreams. The sensations integrate while dozing.

Warmth and Touch

Being held closely against soft skin and enveloped in blankets make up much of a newborn’s world. These cozy tactile experiences probably feature prominently in dreams.

Music Heard While Awake

Lullabies and musical mobiles enjoyed in the nursery may echo through baby’s REM sleep and become the soundtrack of dreams.

Digested Daytime Activities

Mobile infants process new experiences like outside adventures during non-REM sleep. These events and perceptions get integrated into dreams in fragmented ways.

Of course these assumptions about baby dream themes are speculative. But the delighted smiles that often spread across sleeping babies’ faces suggest rich imaginations already hard at work!

Dream States Differ Between Babies and Adults

  • Length: newborns dream in brief minute segments versus continuous narratives lasting over 30 minutes in adults.
  • Nonsensical: babies’ dreams make little logical sense, whereas adult dreams include more complex plotlines and symbolism requiring higher cognition.
  • Primal: babies dream more of physical needs like feeding, touch and motion rather than conceptual scenarios. Their focus is sensory.
  • Risk-Free: babies seemingly have fewer frightening nightmares than adults and children, perhaps owing to limited understanding of dangers real or imagined. Their affect while dreaming seems to remain content, compared to the intense emotions adults display.
  • Easily Forgotten: lacked advanced memory development, infants fail to lock in dreams like adults. You likely won’t hear them recounting dreams from last night!

Sleep Cycling Differs by Age

Understanding how sleep architecture and brain waves mature helps explain developmental differences in dreaming:


  • Dreaming limited to REM, lacking non-REM dreaming
  • Short sleep cycles of 50 minutes
  • Briefer REM cycles of just 5-10 minutes
  • Sleep16 hours daily including naps

6 months

  • More organized sleep with REM/non-REM cycling
  • REM phases lengthen to 15 minutes
  • Sleep consolidating into nighttime
  • Naps decreasing to 3-4 times per day

9 months

  • 18 hour total sleep time
  • Increased non-REM dreaming
  • REM phases of 30-45 minutes
  • Sleep more resembles adult cycles


  • Shift to mostly nighttime consolidates sleep
  • Longest REM cycles reaching over 1 hour
  • Dreams increase in complexity
  • Nightmares and terrors peak

As babies journey through the first months and years, their expanding cognitive abilities and neurological development directly impact the manifestations of dreams.

How Dreams Support Healthy Development

Far from random firings of a baby’s sleeping brain, dreams serve crucial functions for growth and learning:

Memory Building

Dreams help reinforce learned skills practiced while awake like recognizing faces, grasping objects, vocalizing. New connections strengthen.

Emotional Processing

The amygdala governing emotions remains active in REM sleep. Dreaming allows babies to regulate feelings from accumulated daily experiences.

Neural Pathway Pruning

Dreaming eliminates unused neural connections and networks formed during waking hours. The streamlining process aids maturation.

Sensory and Motor Integration

The sights, sounds, smells, motions and tactile sensations absorbed while awake get synthesized by the dreaming brain into sensory memories.

Cognitive Sparring

Dreaming provides a mental playground for “practicing” new thinking abilities in emotional safety, supporting cognitive advancement.

Day in and day out while sleeping, baby’s nonstop dreaming accelerates skill mastery and understanding at lightning speed during this neurologically explosive stage of life!

Clues into Baby Dreams

Cute as they are, the behaviors and motions babies display during sleep provide clues into the dreaming happening internally:

Rapid Eye Movement (REM)

The darting eyes when REM sleep hits looks like baby is intently watching something unfold. Vivid inner imagery is at play.

Facial Movements

Smiles, frowns, pursed lips and grimaces reflect emotions of dreams. The face mirrors inner experiences.

Sounds and Vocalizations

Older babies may babble, hum, laugh or cry out. The sounds respond to dream stimuli.

Sucking Motions

Rhythmic sucking suggests feeding dreams and reinforce development through practice.

Limb Twitching

Jerking arms, legs or fingers resembles waking movement, indicating physical or motion-based dreams.

Changing Breathing Pattern

When dreaming transitions to non-dreaming sleep, breathing becomes more steady and deep versus the irregularity of REM.

While we can’t fully decipher their meaning, these dream-state movements give parents delightful glimpses into their baby’s blossoming inner world.

When Do Children Start Remembering Dreams?

Given infantile amnesia, don’t expect your baby to recount dreams for you. The ability to commit dreams into long term memory develops gradually:

  • Toddlerhood (1-3 yrs): Fragmentary dream memories and retelling simple concepts like colors, shapes, animals. Difficulty distinguishing dreams from reality.
  • Preschool (3-5 yrs): Stories of “monsters” as imagination expands. Sometimes confused whether dreams or real. Consistent dream characters emerge.
  • Early elementary (6-8 yrs): Greater comprehension of the difference between dreams vs waking. More detailed descriptions of plots, settings and characters.
  • Older elementary: Increased insight into meanings and symbolism behind dreams. Linked to emotional experiences. Less confusion between dreams and reality.
  • Adolescence into adulthood: Abstract thinking allows recognizing psychological dream metaphors. Aware of dreams impacting waking moods and behaviors.

In the early years, focus on enjoying your baby’s imaginative inner journeys rather than asking for detailed dream descriptions. Their powers of expression will unfold with time.

How Parents Can Positively Influence Dreams

Babies tune into parents’ voices, motions and touch during wake time and carry them into the dream world. Here’s how to send positive signals:

Talk To Your Baby

Having conversations throughout the day exposes them to more words and speech rhythms that echo through dreams.

Provide Rich Daytime Experiences

Introducing babies to a stimulating range of sights, sounds, smells and activities fuels their dream content.

Read Books Aloud Pre-Bed

Story voices, characters and narratives weave their way into baby’s dreams and spur imaginative thinking.

Give Them Time Outdoors

Nature sights and sounds become the subject of dreams and build cognitive connections.

Be Playful and Animated

Babies integrate fun facial expressions, voices, and exaggerated movements into their dreams and self-development.

Let Them See and Hear Siblings/Pets

Watching interactions between family members and pets sparks social relationship concepts.

Offer Comforting Touch

Soothing hands-on interactions like massage become encoded into dreams about care and affection.

Play Calm Music

Dreaming incorporates music heard while sleeping into rich auditory landscapes.

The more you interactively engage your waking baby, the richer their imaginary worlds expand into while dreaming.

Concerns About Bad Dreams

It’s normal to worry about babies having frightening nightmares. But research suggests:

  • Bad dreams increase starting around age 2 when fears kick in but remain rare in babies.
  • Night terrors due to immature nervous systems differ from actual nightmares. They seem far more alarming to parents than the obliviously sleeping child.
  • Negative dream emotions likely reflect daily stressors that baby lacks the skills to emotionally process while awake. Their brains work it out while dreaming.
  • Nightmares sometimes result from overtiredness or processing overstimulating experiences. Stick to positive calm days.
  • Babies exhibit fewer outward signs of distress during disturbing dreams than older children and adults. The images seemingly don’t upset them.

Take cues from your baby after nighttime distress. If they awaken upset, provide comforting contact. But if they remain settled, likely the dream resolved itself harmlessly.

When Dreams Lead to Sleep Disruptions

If frequent early waking or difficulty settling interferes with baby getting sufficient sleep, try:

  • Maintaining calmer pre-bedtime activities and routines
  • Blocking overstimulating lights, noises, screens before bed
  • Making sure the sleep space feels peaceful and non-threatening
  • Ensuring adequate daytime nutrition and hydration
  • Checking for underlying causes like reflux or allergies with your pediatrician
  • Being responsive to needs causing anxiety like fears about separation
  • Providing transitional objects like loveys to support self-soothing

With consistent support, babies eventually learn to settle themselves back to sleep after normal arousals. Dreams become a peaceful part of healthy sleep cycles.

The Takeaway on Babies’ Dreams

Delving into the question of whether newborns dream inevitably raises more questions than definitive answers. But babies’ observable sleeping behaviors offer intriguing clues into their inner world.

Far from simply the byproduct of random firings of an immature brain, researchers believe infant dreams serve important developmental functions. The sights, sounds and sensations absorbed during the day get processed while dreaming to advance babies’ understanding on many levels.

While babies can’t relay back specific dream details, parents can positively nurture the dreaming process by providing enriching world experiences and warm affection. Feel comforted knowing your sleeping baby is busily building essential skills in their adorable dreaming minds.

Sweet dreams, little one!

Do Babies Dream FAQs:

At what age do babies start dreaming?

Dreaming likely begins in the third trimester while still in the womb. Signs of REM sleep cycles have been detected as early as week 30 of gestation.

Do babies only dream during REM sleep?

Babies start out only dreaming in REM cycles. But around 6 months, non-REM dreaming increases as sleep architecture matures. By 9 months, non-REM and REM cycle proportionally like adults.

What do we know about the content of newborn dreams?

Since babies can’t talk about dreams, we speculate based on what we know occupies babies’ waking hours. Dreams likely focus on faces, motions, physical needs like feeding and familiar routines.

Do babies have nightmares?

While adults worry about babies having bad dreams, infants likely dream more about sensory experiences than scary content. Nightmares increase around age 2 when fears develop but remain rare in infants.

Why do babies seem to startle themselves awake?

Partial arousals coming out of REM sleep are common. Babies lack the ability to settle themselves back into slumber. They need help from parents to reconnect sleep cycles.

How can I tell if my baby is dreaming?

Clues include darting eyes, sucking motions, facial expressions, sounds, twitching and changed breathing patterns. These behaviors result from dream imaging though we can’t know the exact content.

Will rocking or feeding my baby at night disrupt dreaming?

Responding to infant needs overnight with comfort won’t negatively affect the quantity or quality of dreaming. Sleep training guides resettling while minimizing needed parental interventions.

How many dreams do babies have daily?

Newborns dream about 2 hours per day divided into brief 5-10 minute REM cycles multiple times during the night as their sleep architecture is still immature. Dreaming time increases as sleep consolidates.

Why do babies seem unaffected by nightmares?

Research suggests babies exhibit fewer outward signs of distress during bad dreams. While images provoke intense emotions in adults, babies’ limited cognition appears to prevent negative reactivity.

When do children start remembering dreams?

Most children don’t consistently report detailed dream content until elementary age years. Prior to age 3, dreams and reality intermix. By school age, kids discern dreams from wake experiences. Vague memories may persist to toddlerhood.
