The short answer

A realistic newborn schedule is a loop, not a timetable: feed, a short stretch awake, then sleep, around the clock. The AAP puts newborn sleep at about 16 to 17 hours per day, though newborns may only sleep 1 or 2 hours at a time. AAP HealthyChildren The CDC says a breastfed baby feeds about 8 to 12 times in 24 hours. CDC MedlinePlus says newborns stay awake only 1 to 3 hours at a time. MedlinePlus (NIH)

So if you are reading this at 4:10 a.m. with a two week old who fed at 2:30 and is rooting again, nothing has gone wrong with your planning. Nemours KidsHealth writes that newborns don't yet have a sense of day and night, that they sleep around the clock, and that their tiny stomachs send them back to eat often, whatever the hour. Nemours KidsHealth A pattern does come, and the published markers for it are further down. Until then, a good plan does two jobs: it keeps every sleep safe and it keeps the feeds coming.

Below: why there is no clock yet, the numbers behind a newborn day with the organization attached to each one, the loop drawn out, how day and night differ, the four checks for every sleep, the wake-to-feed rule each organization publishes, when a pattern starts to show, and when to call.

Why a newborn has a rhythm and not a schedule

MedlinePlus puts it in one line: at first, your new baby is on a 24-hour feeding and sleep-wake cycle. MedlinePlus (NIH) The AAP adds that babies do not have regular sleep cycles until about 4 months of age. AAP HealthyChildren A timetable written for a two week old is a timetable for a body that is not keeping one yet.

Feeding follows the same logic. For most healthy, full-term infants, the AAP writes, parents can look to their baby rather than the clock for hunger cues, which it calls feeding on demand, or responsive feeding. The same AAP page names the exception, and it matters: for babies born prematurely or with certain medical conditions, scheduled feedings advised by your pediatrician are best. AAP HealthyChildren If that is your baby, the feeding plan your pediatrician gave you comes before anything on this page.

Our guide to the first four weeks says the same thing from the other side: the broken nights of the first month are not a schedule problem to solve.

The numbers behind a newborn day, each with its source

Every figure below is quoted from the body that publishes it, and none is averaged. It is a selection, not every figure each body publishes. The sleep totals and the feeds show two bodies side by side; the night stretch row is MedlinePlus's alone, and the other three organizations' numbers for it are side by side further down, under waking a sleepy newborn to feed.

Part of the dayPublished figureWho publishes it

Sources for the table, row by row: AAP sleep hours AAP HealthyChildren; CDC recommended hours CDC; MedlinePlus awake time MedlinePlus (NIH); CDC breastfeeding CDC; MedlinePlus breastfeeding MedlinePlus (NIH); CDC formula CDC; MedlinePlus formula MedlinePlus (NIH); AAP tummy time AAP HealthyChildren; MedlinePlus night feeds MedlinePlus (NIH).

The two sleep totals share a top of 17 hours and disagree at the bottom, and the NHS publishes a third: it writes that most newborn babies are asleep more than they are awake, and that total daily sleep varies but can be around 18 hours. NHS That spread is the finding, not a problem with the finding. If the hours are the only thing you came for, our short page on how much do newborns sleep answers just that.

A realistic day, drawn as a loop

Put those numbers together and a newborn day is one short loop, run 8 to 12 times, in no fixed order of hours:

  1. Feed, on your baby's cues. The AAP lists licking lips, sticking the tongue out, rooting, hands to the mouth, opening the mouth, fussiness and sucking on everything around, and calls crying a late sign of hunger that can make it hard for a baby to settle down and eat. AAP HealthyChildren Some feeds run long and some short, and the CDC says that is OK: babies will generally take what they need at each feeding and stop eating when they are full. CDC
  2. A short stretch awake. A diaper, a look at your face, and from the first days home a few minutes of tummy time while your baby is awake and closely supervised, 2 to 3 times a day per the AAP. AAP HealthyChildren MedlinePlus puts a newborn's time awake at only 1 to 3 hours at a stretch, and our wake windows by age guide takes that one question further. MedlinePlus (NIH)
  3. Sleepy cues. MedlinePlus lists crying, eye rubbing and fussiness as signs your baby is becoming sleepy. MedlinePlus (NIH)
  4. Sleep, on the back, in their own flat space. Every time, naps included. The four checks are further down.

A small piece of arithmetic, and it is ours, not a published figure: 24 hours shared among 8 to 12 feeds is one loop every 2 to 3 hours, start to start. The CDC's own average for most exclusively breastfed babies is every 2 to 4 hours, and the same page says some babies may feed as often as every hour at times, often called cluster feeding. CDC USDA WIC adds growth spurts to the picture: typically at around 2 to 3 weeks, 6 weeks, 3 months and 6 months, though a given baby's may not come at those exact times. It writes that growth spurts usually last a few days, and that many babies are fussier during them and want to nurse longer and more often. USDA WIC So the loop is an average of uneven days. USDA WIC writes that when feedings are bunched together, especially in the evening, it is called cluster feeding, and that while it may seem like a lot, it is normal. USDA WIC

You may have seen a sample newborn schedule with clock times on it. None of the pages cited here publishes one. What they publish are the ranges in the table, and a timetable built on top of them would be a guess wearing a clock. For how much a newborn eats and how feeds change over the first month, our newborn feeding schedule goes further.

Day loops and night loops are not the same loop

The loop runs around the clock, but it does not have to feel the same at 2 p.m. and 2 a.m. The NHS writes that it's a good idea to teach your baby that night-time is different from daytime from the start: during the day, open curtains, play games and do not worry too much about everyday noises when they sleep. NHS MedlinePlus says it in its own words: expose your newborn to light and noise during the daytime, and as evening or bedtime approaches, dim the lights, keep things quiet and reduce the activity around your baby, and when your baby wakes at night to eat, keep the room dark and quiet. MedlinePlus (NIH)

At night the loop gets smaller. The NHS suggests keeping the lights down low, talking little and quietly, putting your baby down as soon as they have been fed and changed, not changing them unless they need it, and not playing. A baby, in the NHS's word, gradually learns that night-time is for sleeping. NHS The AAP adds one line for the night feed: try not to stimulate or wake babies when you feed or change them during the night, and if you speak, speak softly. AAP HealthyChildren

That is also the honest answer to when a newborn routine can start. The NHS says the day and night difference can be taught from the start. A bedtime routine is a separate and gentler thing. The NHS writes that a simple, soothing bedtime routine may help a baby settle, and suggests, among other things, a bath, night clothes and a fresh nappy, bed, and a story. NHS MedlinePlus, in its section for infants 3 to 12 months, asks that the bedtime routine be consistent and pleasant, with the last night feed shortly before bed, and never to bed with a bottle. MedlinePlus (NIH) The NHS names no age to begin, and neither will we.

Every sleep in the loop gets the same four checks

Schedule pages tend to skip this part, and it is the one part of the day that does not change between week one and week twelve. Every sleep, including the twenty minute nap after lunch:

  • On the back. NICHD Safe to Sleep: place babies on their backs to sleep for naps and at night, and it is not safe to place babies on their sides or stomachs to sleep, not even for a nap. NICHD Safe to Sleep
  • On a firm, flat, level surface with only a fitted sheet. Also NICHD Safe to Sleep. NICHD Safe to Sleep
  • In the same room as you. The NHS advises keeping your baby in the same room as you for every sleep, both day and night, for at least the first 6 months, and writes that this can reduce the risk of SIDS. NHS
  • Not left asleep in a seat, a sling, or on a couch. NICHD Safe to Sleep says not to use sitting devices such as car seats and strollers, or carrying devices such as carriers and slings, for regular sleep or naps, and if your baby falls asleep in one, to move them to their regular sleep space as soon as possible once you are out of the vehicle. NICHD Safe to Sleep It also writes that babies should never sleep on an adult bed, couch or armchair, and that couches and armchairs are particularly dangerous when an adult falls asleep on them while feeding or comforting a baby. NICHD Safe to Sleep

That last one is the check a tired night breaks, and NICHD Safe to Sleep names the moment: an adult falling asleep on a couch or armchair while feeding or comforting a baby. The whole setup, room by room, is in our safe sleep guide.

Waking a sleepy newborn to feed: four organizations, their own numbers

Here is where the published guidance does set a limit on the clock. Early on, the worry it names is sleep that goes on too long.

  • CDC. At first, babies need to eat every 2 to 4 hours to get enough nutrition and to grow, and you may need to wake your baby to feed. Patting, stroking, undressing, or changing the diaper can help wake them. CDC
  • MedlinePlus. No more than 4 hours asleep at night without a feed, or 4 to 5 hours if you are feeding formula, and it is OK to wake your baby up to feed. MedlinePlus (NIH)
  • AAP, for formula feeding. If your baby sleeps longer than 4 to 5 hours during the first few weeks after birth and starts missing feedings, wake them up and offer a bottle. AAP HealthyChildren
  • Nemours KidsHealth. Wake your baby every 3 to 4 hours to eat until they show good weight gain, which usually happens within the first couple of weeks. After that, it is OK to let your baby sleep for longer periods at night. Nemours KidsHealth

Four bodies, four sets of numbers, and we are not averaging them. What they share is the direction: in the early weeks, a long sleep can be a reason to wake for a feed. They mark the end differently: the CDC says "at first", the AAP's formula page says "during the first few weeks after birth", MedlinePlus names no end, and Nemours KidsHealth ties it to good weight gain, which it says usually happens within the first couple of weeks. The person who can tell you your baby is there is your pediatrician, who has the weight chart. The CDC's own line: if you have concerns about how much your baby is sleeping or eating, talk to their doctor or nurse. CDC

When a pattern starts to show

Slowly, and from several directions at once. These are the published markers, and every one of them is a spread rather than a date.

  • Longer gaps between feeds. The CDC writes that as a baby grows they drink more at each feeding and the time between feedings gets longer. CDC
  • The wake-to-feed rule relaxes. Once there is good weight gain, which Nemours KidsHealth says usually happens within the first couple of weeks. Nemours KidsHealth
  • Fussing peaks, then eases. The AAP writes that regular daily fussing usually peaks at about 3 hours a day by 6 weeks old, then declines to 1 or 2 hours a day by 3 to 4 months of age. AAP HealthyChildren The NHS writes that a baby may have colic if they cry more than 3 hours a day, 3 days a week for at least 1 week but are otherwise healthy, and that colic is a common problem that should get better by around 3 or 4 months of age. NHS The AAP's colic page adds that colicky behavior may also signal a medical problem, such as a hernia or some type of illness, so crying that worries you is a reason to call your pediatrician. AAP HealthyChildren Two kinds of cry are more urgent than that on the NHS's own colic page; they are under Call 911 below.
  • A first longer night stretch, for some. Nemours KidsHealth writes that some babies start to sleep through the night, meaning 5 to 6 hours at a time, by 2 to 3 months, and some do not. Nemours KidsHealth Our article on when babies sleep through the night takes that phrase apart.
  • Regular sleep cycles. About 4 months of age, per the AAP. AAP HealthyChildren

This page stops at 12 weeks because that is roughly where the newborn guidance it quotes stops too. What comes after, including why 4 months can feel like a step backwards, is in our 4 month sleep regression article.

When to call, and when to call 911

The lists below come from different organizations and are kept apart on purpose. Merging them would mean deciding for you which items are emergencies, and that decision belongs to the people who published them. None of these thresholds is ours.

Call 911

Seattle Children's Hospital, in its handout on signs of respiratory distress in infants (PE1736, 2024), publishes four things that mean call 911 now: they stop breathing for 15 seconds or longer; they have severe difficulty breathing; they have blue-tinged skin, especially noticeable around the lips, fingernails and gums, which the handout says may not be visible on darker skin tones, so pay close attention to your child's breathing and behavior; and you are unable to wake your baby. Seattle Children's PE1736

The NHS colic page, written for the UK, puts two signs under immediate action, where it says to go to A&E or call 999: your baby has a weak or high-pitched cry, or your baby's cry does not sound like their normal cry. A&E and 999 are the UK's emergency department and emergency number; in the US, that is the emergency room or 911. NHS

Call your baby's doctor

  • Fever at 3 months or younger. The AAP (Fever and Your Baby, updated 2025) writes that if your baby is 3 months of age or younger and has a rectal temperature of 100.4 degrees Fahrenheit (38 degrees Celsius) or higher, call your pediatrician immediately, and adds: this is very important, even if your baby shows no other signs or symptoms of being ill. AAP HealthyChildren
  • Yellow skin or eyes (jaundice). The AAP (Jaundice in Newborns, updated 2024) says to call your baby's doctor if your baby's skin turns more yellow, if the abdomen, arms or legs are yellow, if the whites of the eyes are yellow, or if your baby is hard to wake, fussy, or not nursing or taking formula well. AAP HealthyChildren
  • The AAP's check on waking your baby at night. The AAP (Sleeping Through the Night, 2013) says to check with your pediatrician about nighttime awakening if your baby is not growing and gaining weight steadily; feeding well 8 to 12 times a day breastfeeding, or 5 to 8 times a day bottle-feeding; urinating normally with at least 4 wet diapers a day; and having at least 3 normal bowel movements per day. AAP HealthyChildren
  • Signs of dehydration. The AAP (Signs of Dehydration in Infants and Children, updated 2019) says to notify the pediatrician immediately if any of these develop: plays less than usual; urinates less frequently, for infants fewer than six wet diapers per day; a parched, dry mouth; fewer tears when crying; a sunken soft spot of the head; and, depending on the cause, loose stools or fewer bowel movements. That page's six wet diapers and the 4 wet diapers in the check above come from two AAP pages answering two different questions, and we print both rather than pick one. AAP HealthyChildren Two more pages publish a daily count for the same sign. A third AAP page, How Often and How Much Should Your Baby Eat? (updated 2024), says a baby should have 2 to 3 wet diapers each day in the first few days after birth and at least 5 to 6 wet diapers a day after the first 4 to 5 days, and that by the fourth day a baby should be having at least 4 stools a day, the exact number depending on whether they are breastfed or formula-fed. AAP HealthyChildren MedlinePlus lists, among the signs your baby is getting enough to eat, that once your milk comes in, a baby should have at least 6 wet diapers and 3 or more dirty diapers a day. MedlinePlus (NIH)
  • Signs of severe dehydration. The same AAP dehydration page prints a second, separate list for severe dehydration, in addition to the signs above, under the same instruction to notify the pediatrician immediately: very fussy; excessively sleepy; sunken eyes; cool, discolored hands and feet; wrinkled skin; and urinates only one to two times per day. AAP HealthyChildren
  • Any worry about sleep or feeding. The CDC: if you have concerns about how much your baby is sleeping or eating, talk to their doctor or nurse. CDC

Notice the different wordings. On its jaundice page, the AAP lists a baby who is hard to wake among reasons to call the doctor, and on its dehydration page it lists one who is excessively sleepy among signs to notify the pediatrician immediately. Seattle Children's lists a baby you are unable to wake as a reason to call 911. We print each exactly as written and do not draw the line between them for you: if you are not sure which one you are seeing, call 911. And over all of it: if your baby seems unwell to you, call your pediatrician at any hour.

A note from the editor. A newborn day that looks nothing like a chart is still a newborn day. Every published number on this page names the organization behind it, and the one piece of arithmetic is labelled as ours. A baby outside a range is not a verdict on your baby. If your baby was born prematurely or with certain medical conditions, the AAP's own exception applies and your pediatrician's plan comes first. And if today feels different from the days you know, trust that and call.

FAQ

What is a realistic schedule for a newborn baby?

A loop rather than a clock: feed, a short stretch awake, then sleep, repeated around the clock. The AAP puts newborn sleep at about 16 to 17 hours per day, though newborns may only sleep 1 or 2 hours at a time. The CDC says a breastfed baby feeds about 8 to 12 times in 24 hours, and MedlinePlus says newborns stay awake only 1 to 3 hours at a time.

When should you start a schedule with a newborn?

For feeding, the AAP's answer for most healthy, full-term infants is to look to the baby rather than the clock, which it calls responsive feeding. Babies born prematurely or with certain medical conditions are the exception, and for them the AAP says scheduled feedings advised by the pediatrician are best. For sleep, the AAP writes that babies do not have regular sleep cycles until about 4 months of age.

When should you start a sleep routine with a newborn?

The NHS says to teach your baby that night-time is different from daytime from the start: curtains open and play in the day, lights low and voices quiet at night. For a bedtime routine, the NHS says a simple, soothing one may help a baby settle and names no age to start. MedlinePlus places its bedtime routine advice under infants 3 to 12 months and asks that it be consistent and pleasant.

Can I let my newborn sleep 5 hours?

In the early weeks, the published limits sit at or below 5 hours. MedlinePlus says a baby should not sleep more than 4 hours at night without feeding, or 4 to 5 hours on formula. Nemours KidsHealth says to wake your baby every 3 to 4 hours until good weight gain, which usually comes within the first couple of weeks, and that longer night sleep is fine after that. Your pediatrician, who sees the weight chart, confirms when.

How long should you let a newborn sleep at a time?

The AAP says newborns may only sleep 1 or 2 hours at a time. On the upper limit, each organization publishes its own number: MedlinePlus says not more than 4 hours at night without a feed, or 4 to 5 hours on formula; the AAP says to wake a formula-fed baby who sleeps longer than 4 to 5 hours in the first few weeks and starts missing feedings; the CDC says that at first babies need to eat every 2 to 4 hours; and Nemours KidsHealth says to wake your baby every 3 to 4 hours until good weight gain. If you have concerns about how much your baby is sleeping or eating, the CDC says to talk to their doctor or nurse.

What week is hardest with a newborn?

No organization we cite names a hardest week, and families answer it differently. Two published patterns do meet around week six. The AAP writes that regular daily fussing usually peaks at about 3 hours a day by 6 weeks old and eases to 1 or 2 hours by 3 to 4 months, and USDA WIC writes that growth spurts typically happen at around 2 to 3 weeks, 6 weeks, 3 months and 6 months, though a given baby's may not come at those exact times, and that many babies are fussier during them and want to nurse longer and more often. The AAP's colic page adds that colicky behavior may also signal a medical problem, such as a hernia or some type of illness, so crying that worries you is a reason to call your pediatrician.

What is the 3-3-3 rule for newborns?

None of the organizations cited on this page publishes a 3-3-3 rule for newborns, and we did not find a health body that does, so we will not invent one. The nearest published rule of threes is about crying, not schedules: the NHS says a baby may have colic if they cry more than 3 hours a day, 3 days a week for at least 1 week but are otherwise healthy. The AAP's colic page adds that colicky behavior may also signal a medical problem, such as a hernia or some type of illness, so crying that worries you is a reason to call your pediatrician. The same NHS page lists a weak or high-pitched cry, or a cry that does not sound like your baby's normal cry, as needing immediate action: in the UK it says to go to A&E or call 999, and in the US that is the emergency room or 911.

Is it normal for my newborn to sleep all day?

Newborns sleep for most of the day and night: the AAP puts it at about 16 to 17 hours, and Nemours KidsHealth writes that newborns don't yet have a sense of day and night. Sleeping through feeds is a separate question. The CDC says that at first babies need to eat every 2 to 4 hours and you may need to wake them, and adds: if you have concerns about how much your baby is sleeping or eating, talk to their doctor or nurse. Seattle Children's lists being unable to wake your baby as a reason to call 911. If your baby also looks yellow, the AAP's jaundice page lists being hard to wake among reasons to call the doctor. If you are not sure whether your baby is hard to wake or unable to wake, call 911.
