Baby Is Restless and Tossing All Night
The short answer
Some degree of restless sleep is normal, especially as babies learn to roll and move. Babies cycle through light and deep sleep, and movement during light sleep phases is common. However, consistently very restless sleep with frequent arousals may be related to discomfort, sleep environment, or rarely, sleep-disordered breathing.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
Newborns are naturally restless sleepers with grunting, squirming, and brief movements. This is called active sleep (REM) and makes up about 50% of their sleep. It does not mean they are uncomfortable.
As babies learn to roll and move, they may move extensively during sleep. This is often worse during developmental leaps. Ensure the sleep space is safe with no loose items.
Movement during sleep is normal. Babies may end up in every corner of the crib. If restlessness is accompanied by snoring, mouth breathing, or sweating, mention it to your pediatrician.
Some children are naturally active sleepers. If your toddler seems restless but wakes refreshed, it is likely their normal pattern. Persistent restlessness with daytime sleepiness may warrant evaluation.
What Should You Do?
When to take action
- Baby moves around the crib but stays asleep
- Restlessness during light sleep phases with periods of still deep sleep
- Baby wakes refreshed despite apparent restlessness
- Movement increases during developmental milestones
- Baby is restless all night and wakes frequently seeming uncomfortable
- Restless sleep is accompanied by snoring or mouth breathing
- Baby seems tired during the day despite sleeping adequate hours
- Baby has pauses in breathing during restless sleep
- Baby has rhythmic jerking movements that could indicate seizure activity

Baby Rolling Over in Sleep
Once your baby can roll from back to tummy and tummy to back on their own, it is safe to let them sleep in whatever position they choose. You should always place your baby on their back to start sleep, but you do not need to reposition them if they roll over during the night.
Snoring in Babies and Toddlers
Occasional snoring during a cold or when congested is common and usually harmless. However, habitual snoring - snoring most nights when healthy - occurs in about 10-12% of children and may indicate a condition called obstructive sleep apnea (OSA), which can affect development, behavior, and health if untreated. Any child who snores regularly when not sick should be evaluated by their pediatrician.
My Baby Sweats a Lot During Sleep
Babies commonly sweat during sleep, especially on their heads, because they spend more time in deep sleep than adults and have developing temperature regulation systems. Most of the time, it's simply that the room is too warm or your baby is over-dressed. Occasional sweating is normal, but excessive or persistent sweating warrants a pediatrician check.
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.
