Baby Sleep

What actually helps.

Safe sleep, newborn sleep, routines, naps, swaddling, and the things worth knowing before you buy another sleep product.

Baby sleep advice can get very loud very quickly. This guide separates what is about safety from what may help your baby sleep better. The safe-sleep recommendations come from pediatric and public-health guidance; routines and sleep strategies are practical options, not promises. — Anahely

A note before we begin: This guide is educational and does not replace your pediatrician's advice. Babies born prematurely, babies with medical conditions, or babies with feeding, breathing, or growth concerns may need individualized guidance.

Start With Safe Sleep

The most important sleep advice is also the simplest: every sleep should start with a safe environment.

BackPlace your baby on their back for every nap and nighttime sleep until age 1.

Firm + flatUse a firm, flat, level, non-inclined sleep surface designed for infants.

EmptyKeep pillows, blankets, stuffed toys, bumpers, positioners, and other loose items out of the sleep space.

SeparateRoom-share with your baby while keeping baby on their own sleep surface.

RememberThink: back + firm + flat + empty + separate. A fitted sheet on a safety-approved crib, bassinet, portable crib, or play yard is the basic setup.

How Much Sleep Does a Baby Need?

These are recommended total sleep ranges over 24 hours. They are ranges, not schedules, and individual babies can vary.

Age	Recommended sleep	What it means
0–3 months	14–17 hours / 24 hours	Newborn sleep is usually broken into many shorter periods.
4–12 months	12–16 hours / 24 hours	This total includes naps.
1–2 years	11–14 hours / 24 hours	This total includes naps.

ImportantA sleep recommendation is not a requirement for one perfect day. Look at your baby's overall pattern, development, feeding, and your pediatrician's guidance rather than comparing one night with another.

Newborn Sleep Is Supposed to Be Messy

Newborns do not have regular sleep cycles yet. The American Academy of Pediatrics notes that newborns may sleep around 16–17 hours a day but may sleep only 1–2 hours at a time.

Short stretchesFrequent waking is normal in the newborn stage.

Frequent feedsNewborns wake often because they need regular feeding.

Day/night confusionYour baby may not yet understand that nighttime is for longer sleep.

Changing patternsOne night can look completely different from the next.

Take the pressure offYou are not creating a “bad sleeper” because your newborn wakes up. Newborns are not expected to sleep through the night.

Help Baby Learn the Difference Between Day & Night

You cannot force a newborn onto a schedule, but you can give their developing body clock useful cues.

During the dayOpen the curtains, allow normal household sounds, talk and interact with your baby, and offer age-appropriate awake time and supervised tummy time.

At nightKeep lights low, keep interactions calm, and make feeding and diaper changes quiet and boring rather than turning them into playtime.

As babies get older, a consistent bedtime routine can help them know what comes next: diaper, pajamas, feeding, a short book or song, then sleep.

Swaddling: Helpful, But There Is a Line

Swaddling can calm some newborns, but it does not reduce the risk of SIDS. If you swaddle, keep the basics of safe sleep unchanged.

Always place a swaddled baby on their back.
Keep the swaddle snug around the upper body but allow the hips and legs to move freely.
Do not use weighted swaddles or add weighted objects.
Stop swaddling as soon as your baby shows signs of trying to roll, which can happen earlier than parents expect.
Watch for overheating; baby should not be sweaty, flushed, or hot to the touch.

Worth knowingOnce you stop swaddling, a wearable blanket that leaves the arms free can be a practical alternative. It should not be weighted.

Pacifiers & Sleep

The AAP recommends considering a pacifier at naps and bedtime because pacifier use is associated with a lower risk of SIDS.

If breastfeeding, many families wait until breastfeeding is well established before introducing a pacifier; ask your healthcare provider if you are unsure.
If the pacifier falls out after your baby falls asleep, you do not need to put it back.
Do not attach a pacifier to your baby's neck, clothing, or a toy during sleep.
It is okay if your baby does not want a pacifier.

What About Reflux?

A baby with reflux should still be placed on their back to sleep.

DoUse a firm, flat, level sleep surface and follow your pediatrician's feeding and reflux guidance.

Don'tElevate the crib mattress, use wedges or positioners, or let baby routinely sleep propped up.

Back sleeping on a flat surface does not increase the risk of choking or aspiration in healthy infants, including infants with gastroesophageal reflux, according to the AAP.

Sleep Training: What We Know

Sleep training is often discussed as though there is one correct age and one correct method. There isn't.

Newborn stage

Prioritize feeding, growth, safe sleep, day/night cues, calming routines, and responding to your baby's needs. Newborn sleep is naturally fragmented.

As baby gets older

Families may choose different approaches to help a baby learn to settle and return to sleep. A consistent bedtime routine and, for babies developmentally ready, putting them down drowsy but awake can be useful strategies.

Key distinctionSleep training is not the same thing as safe sleep. You can choose a sleep strategy that fits your family while still following safe-sleep recommendations every time.

Sleep Products You Can Skip

A product marketed as a “sleep solution” is not automatically a safe sleep surface.

Inclined sleepersAvoid infant sleep products with inclined sleep surfaces. The CPSC says inclined sleepers with sleep surfaces greater than 10° are banned hazardous products for infants.
Crib bumpersSkip padded crib bumpers and products that add material around the inside of the crib.
Weighted sleep productsAvoid weighted blankets, weighted swaddles, and other weighted objects on or near a sleeping infant.
Sleep positioners and nestsThese do not replace a firm, flat, empty infant sleep surface and can create suffocation or entrapment hazards.
Pillows and loose blanketsKeep them out of an infant's sleep space. Use appropriate clothing or an unweighted wearable blanket instead.

A Realistic Newborn Night

Instead of promising that your newborn will sleep through the night, set a more realistic goal:

The goalFeed → change → calm → safe sleep → repeat. Your newborn's frequent waking is part of this stage. The win is creating a safe, manageable rhythm—not achieving a perfect schedule.

For your own sleep, build a plan with your partner or support person for who handles feeds, changes, meals, and household tasks when possible. If you are extremely sleepy, avoid feeding or comforting baby on a couch or armchair where you could unintentionally fall asleep.

When to Call Your Pediatrician

Sleep questions are often really questions about feeding, breathing, growth, or development. Contact your baby's healthcare provider if you are worried about your baby's sleep or if something feels different from your baby's usual pattern.

Seek individualized medical advice for babies who were born prematurely, have a medical condition, have feeding or growth concerns, or have unusual breathing or difficulty waking for feeds. If your baby has an emergency or is having trouble breathing, seek emergency medical care.

Frequently Asked Questions

How long should a newborn sleep?

Newborns 0–3 months are generally recommended to get 14–17 hours of sleep in 24 hours. That sleep is usually divided into many shorter stretches.

Should newborns sleep on their side?

No. Babies should be placed on their backs for every sleep until age 1. Side sleeping is not considered a safe alternative.

Can a baby with reflux sleep on their back?

Yes. The AAP recommends back sleeping on a firm, flat, non-inclined surface, including for babies with gastroesophageal reflux.

When should I stop swaddling?

Stop as soon as your baby shows signs of trying to roll. Rolling can happen earlier than expected, so do not wait for a specific age if your baby is already attempting it.

Is room sharing safer than bed sharing?

Yes. The AAP recommends room sharing without bed sharing. Keeping baby close to your bed on a separate infant sleep surface is safer than sharing the adult bed.

When will my baby sleep through the night?

There is no single age that applies to every baby. Newborns commonly wake frequently to feed, and sleep patterns mature over time.

Can I put a blanket in my baby’s crib?

For infants, the recommended sleep space is bare except for a fitted sheet on the mattress. Use appropriate clothing or an unweighted wearable blanket instead of loose bedding.

Are sleep sacks safe?

An appropriately sized, non-weighted wearable blanket can be used as an alternative to loose blankets. Follow the product’s safety and sizing instructions and avoid overheating.

Do pacifiers reduce SIDS risk?

Pacifier use at naps and bedtime is associated with a reduced risk of SIDS. If breastfeeding, discuss timing with your healthcare provider.

Is sleep training the same as safe sleep?

No. Sleep training refers to approaches that may help a baby learn sleep skills. Safe sleep is about reducing the risk of sleep-related injury and death and applies every time an infant sleeps.
