Night Waking by Age: How Often Is Normal?
The short answer
Night waking is biologically normal for infants and toddlers, yet it remains one of the most stressful aspects of parenting. Research published in Pediatrics shows that "sleeping through the night" (defined as 5+ consecutive hours) is achieved by about 57% of 6-month-olds and only 72% of 12-month-olds, meaning nearly 1 in 3 one-year-olds still wakes at night. General benchmarks: newborns wake every 2-3 hours (stomach capacity requires frequent feeds), 3-6 month-olds may have 1-3 night wakings, 6-12 month-olds typically have 0-2 wakings, and toddlers may have 0-1 wakings. However, these are averages, and there is wide normal variation. A 2018 study in Pediatrics found that 27% of 6-month-olds and 13% of 12-month-olds did not sleep 6 consecutive hours, with no negative effects on development or maternal mood compared to those who did. Night waking does not mean your baby has a "sleep problem" or that you have done something wrong.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
0-3 months
Newborns lack a consolidated circadian rhythm and need to eat every 2-3 hours (breastfed) or 3-4 hours (formula-fed). Waking 3-5 times per night is typical and necessary for caloric intake and growth. Around 6-8 weeks, some babies begin having one longer sleep stretch (3-5 hours), usually in the first part of the night. This is normal and does not need to be forced. Never withhold nighttime feeds from a young infant to "train" them to sleep longer, because they need the calories.
3-6 months
Night wakings typically decrease to 1-3 per night. Many babies develop a longer first stretch of 4-6 hours. The 4-month sleep regression is a normal developmental shift where sleep architecture matures, often temporarily increasing night wakings. After 4 months, some pediatricians consider sleep training methods appropriate if parents desire. However, 1-2 night feeds at this age are still biologically expected, and the AAP does not recommend night-weaning before 6 months for most babies.
6-12 months
Most babies are physiologically capable of sleeping longer stretches but many continue to wake 1-2 times. Common causes include: teething, developmental milestones (sitting, crawling, standing), separation anxiety (peaks 8-10 months), illness, and habitual wake-ups. If your baby wakes twice at 8 months but is growing well and happy during the day, this is within the normal range. Research shows no developmental advantage to early consolidated sleep. Your baby is not falling behind because they still wake at night.
12-24 months
About 85-90% of toddlers sleep through most nights by 12-18 months, but occasional wakings remain normal. New teeth (molars at 13-19 months), illness, nightmares, and schedule changes (dropping naps, travel) can all cause temporary regressions. If your toddler was sleeping through the night and begins waking again, this is almost always a phase lasting 1-3 weeks. Toddlers who never slept through the night are still developmentally normal; sleep consolidation timing is largely temperament-driven and not a reflection of parenting quality.
What Should You Do?
When to take action
- Newborn waking every 2-3 hours for feeds
- A 6-month-old still waking 1-2 times per night
- A 12-month-old waking once per night, especially during teething or illness
- Sleep patterns that are inconsistent (one good night followed by a rough one)
- Your baby's pattern not matching a friend's baby of the same age, since individual variation is wide
- Your baby's night wakings have suddenly and significantly increased (from 1 to 5+) without obvious cause
- Your baby seems in pain during night wakings (crying intensely, pulling at ears, or arching)
- Night wakings are accompanied by snoring, gasping, or paused breathing that may indicate sleep apnea
- You are so sleep-deprived that you feel unsafe driving or caring for your baby, so discuss your own health with your provider
- Your baby has long pauses in breathing (more than 10-15 seconds) during sleep, followed by gasping, which requires evaluation for obstructive sleep apnea
- Your baby is difficult to wake from sleep, unusually limp, or unresponsive: this is a medical emergency
- Night wakings are accompanied by persistent fever, vomiting, or refusal to feed, which suggest illness needing evaluation

Related Sleep Concerns
Baby Is Restless and Tossing All Night
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.
My Baby Still Feeds Excessively at Night
Frequent night feeding is biologically normal for young babies, as their small stomachs need regular refueling. However, by 6 months most healthy, full-term babies who are gaining weight well are developmentally capable of going longer stretches at night. If your baby is still feeding very frequently at night, it may be a habit pattern that can be gently adjusted.
4-Month Sleep Regression
The 4-month sleep regression is actually a permanent maturation of your baby's sleep architecture, not a temporary setback. As your baby's brain develops, their sleep cycles become more adult-like with distinct stages, which can temporarily cause more frequent waking. This is a sign of healthy neurological development.
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.
