A one-week-old baby should sleep roughly 14 to 17 hours over each 24-hour period, with some newborns logging as much as 18 or 19 hours. That sleep won’t come in long, predictable blocks, though. It arrives in short bursts spread across day and night, shaped by a tiny stomach that needs frequent refilling.
Total Sleep in the First Week
The National Sleep Foundation puts the recommended range at 14 to 17 hours per day for newborns. That range is wide because individual babies vary considerably. A baby sleeping 15 hours is just as normal as one sleeping 18. What matters more than hitting an exact number is that your baby is feeding well, producing wet and dirty diapers, and gaining weight on schedule.
Almost none of those hours will happen in one stretch. At this age, sleep comes in chunks of roughly 45 minutes to two hours, sometimes three. Your baby’s stomach is still tiny, holding only small amounts of milk at a time, so hunger interrupts sleep frequently. Expect to feed about 8 to 12 times per day, which works out to roughly every two to three hours around the clock.
Why Newborns Wake So Often
A one-week-old’s sleep cycles are fundamentally different from yours. About half of a newborn’s sleep is active sleep (the infant version of REM), during which you’ll notice fluttering eyelids, irregular breathing, small twitches, and even faint smiles. The other half is quiet, deeper sleep. A full cycle through both stages is short, and the transitions between them create natural wake points.
On top of that, newborn stomachs can only hold small volumes of breast milk or formula. This biological limit means your baby genuinely needs to eat every two to three hours. If your one-week-old has been sleeping for more than four hours without feeding, it’s generally a good idea to gently wake them. Consistent feeding in these early days supports healthy weight gain and helps establish your milk supply if you’re breastfeeding.
Wake Windows at One Week
The time a one-week-old can comfortably stay awake between naps is remarkably short: about 30 minutes to one hour. That window includes feeding, a diaper change, and maybe a few minutes of quiet alertness before sleepiness sets in again. Trying to keep a newborn awake longer than this usually backfires, leading to overtiredness and fussier sleep.
Watch for early tired signs: jerky arm or leg movements, yawning, turning away from faces or stimulation, and fussing that isn’t hunger-related. Hunger cues look different. A hungry baby brings their hands to their mouth, turns their head toward your breast or the bottle (called rooting), and smacks or licks their lips. Clenched fists can also signal hunger. Crying is typically a late hunger sign, not an early one, so responding to the quieter cues helps keep feedings calmer.
Day-Night Confusion Is Normal
Many one-week-old babies sleep more during the day and have their longest alert stretches at night. This isn’t a sleep problem. Newborns haven’t developed a circadian rhythm yet, so they have no internal sense of day versus night. That internal clock starts to mature over the first few months of life.
You can help the process along with simple environmental cues. During the day, let your baby nap in naturally lit, normally noisy areas of the house. Don’t tiptoe around or darken the room for daytime sleep. At night, do the opposite: keep the room dark, use a soft voice, and limit interactions to feeding, burping, changing, and gentle soothing. This contrast won’t produce instant results at one week, but it begins building the associations your baby will rely on as their rhythm develops.
Safe Sleep Setup
Because your baby will be sleeping so many hours each day, the sleep environment matters from the very first week. The American Academy of Pediatrics recommends placing infants on their backs for every sleep, on a firm, flat mattress in their own sleep space, whether that’s a crib, bassinet, or portable play yard with a fitted sheet. The sleep area should be free of loose blankets, pillows, stuffed animals, and bumper pads.
Avoid letting your baby sleep on a couch, armchair, or in a device like a swing or car seat (unless actively riding in the car). Room-sharing, where your baby sleeps in their own space but in the same room as you, makes nighttime feeds easier and is associated with lower risk of sleep-related infant deaths. These guidelines apply to every sleep, including short naps during the day.
What “Too Much” or “Too Little” Sleep Looks Like
At one week old, there’s a wide range of normal. A baby consistently sleeping under 14 hours or well over 19 hours, especially if paired with poor feeding, very few wet diapers, or difficulty waking for feeds, may need a pediatric check. The key indicators of healthy newborn sleep are that your baby wakes on their own or rouses relatively easily for feedings, feeds actively once awake, and has at least six wet diapers and several stools per day by the end of the first week.
A deeply sleeping baby who is difficult to wake, feeds poorly when awake, or shows a significant drop in wet diapers looks different from a baby who simply sleeps a lot but feeds well. If you’re noticing those patterns together, your pediatrician can check for dehydration or other concerns quickly and easily.
