My Toddler Talks in Their Sleep
The short answer
Sleep talking (somniloquy) is very common in children and is almost always harmless. Studies suggest that about half of all children talk in their sleep at some point. It can range from mumbling and gibberish to clear words or even short sentences. Sleep talking typically occurs during transitions between sleep stages and is not a sign of a sleep disorder, emotional distress, or neurological problem. Your toddler will not remember talking in their sleep.

By Age
What to expect by age
0-12 months
Babies make many sounds during sleep including grunting, cooing, whimpering, and brief cries. This is normal and related to active (REM) sleep, which makes up a large proportion of infant sleep. These vocalizations are not true sleep talking but are part of normal infant sleep physiology. You do not need to respond to every sound — many babies settle themselves back into deeper sleep within a few moments if left undisturbed.
12-24 months
As your toddler's language develops, you may start to hear recognizable words during sleep. This can coincide with language explosions — some parents notice more sleep talking when their toddler is learning many new words. Sleep talking at this age is usually brief and occurs during the first third of the night during non-REM sleep transitions. It does not disrupt sleep quality and your toddler will not remember it. There is no need to wake them or respond.
2-4 years
Sleep talking may become more elaborate as vocabulary grows. Your toddler might say full sentences, appear to have conversations, or even laugh during sleep. This can be amusing or unsettling for parents but is benign. Sleep talking tends to run in families and can increase during periods of stress, illness, fever, or when your child is overtired. Ensuring adequate sleep and a consistent bedtime routine can reduce the frequency. If sleep talking is accompanied by sleepwalking, night terrors, or disruptive behaviors, mention this to your pediatrician.
What Should You Do?
When to take action
- Your toddler mumbles, says words, or even speaks short sentences during sleep and does not remember in the morning
- Sleep talking happens occasionally, perhaps a few times a week, and does not wake your child
- Sleep talking increases when your toddler is overtired, sick, or going through a developmental leap
- Other family members also talk in their sleep — there is a strong genetic component
- Sleep talking is accompanied by frequent sleepwalking, night terrors, or other disruptive sleep behaviors
- Your toddler seems distressed during sleep talking episodes and is difficult to console
- Sleep talking is so loud or frequent that it consistently disrupts other family members' sleep
- Your toddler has episodes that seem like seizures during sleep — rhythmic jerking, stiffening, or eyes rolling
- Your toddler is difficult to wake, confused, or has other neurological changes after nighttime episodes
- Your toddler's nighttime episodes began after a head injury

Related Sleep Concerns
Sleepwalking Safety for Toddlers
Sleepwalking affects about 15% of children, typically beginning between ages 2-6. It occurs during deep non-REM sleep and is not a sign of emotional problems, stress, or neurological issues. Your child will not remember the episode. Sleepwalking tends to run in families and most children outgrow it by adolescence. The primary concern is safety — ensuring your home is secure so your child cannot hurt themselves or leave the house during an episode.
Toddler Night Terrors
Night terrors are a common and harmless sleep phenomenon where your child appears terrified - screaming, thrashing, or sitting up - but is actually still asleep and will not remember the episode. They are caused by a partial arousal from deep sleep and are not a sign of emotional distress or psychological problems.
My Baby Screams in Their Sleep
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.
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.
