Willo phase 1: The Arrival
Phase 1 of 35 · 0–2 weeks

The Arrival: your baby at 0 to 2 weeks

The first two weeks are mostly sleeping, feeding and being held, and that is exactly as it should be.

In the first two weeks, most newborns sleep 14 to 17 hours across each 24 hour day in short stretches of 2 to 4 hours, feed 8 to 12 times, and stay awake only 30 to 60 minutes at a time. Vision is blurry beyond about 8 to 12 inches, and most movement is still reflex.

Nothing about this stage is meant to look like a routine yet. A newborn body clock has not formed, so day and night blur together and feeds drive the whole rhythm. Most babies lose 7 to 10 percent of their birth weight in the first days and are back to it by around two weeks. Ranges are wide, and healthy babies sit all across them.

What may be happening

Body

  • Most of what your baby does in these first days is reflex, including rooting toward a nipple, sucking, gripping a finger and the startle that throws their arms wide.
  • Neck muscles are not ready to hold the head yet, so the head needs supporting every time your baby is lifted or moved.
  • A head that looks pointed or uneven from the birth often rounds out over the first days, and the umbilical stump usually dries and drops off somewhere between about 10 days and 3 weeks.
  • Peeling skin, fine body hair and blotchy mottling are common in the first week or two and generally settle on their own.

Brain

  • Sight is short range at this age, with most newborns seeing most clearly at about 8 to 12 inches, roughly the distance from your arms to your face.
  • High contrast edges hold attention far better than pastel colours or fine detail.
  • Hearing is already well developed, and many babies quieten or turn slightly toward a voice they heard before birth.
  • Sleep is broken into short cycles with a large share of light, twitchy sleep, which is part of how the newborn brain builds connections.

Connection

  • Crying is the only signal your baby has, and in these first weeks it is usually about hunger, temperature, tiredness or wanting to be held.
  • Skin to skin contact often steadies a newborn heart rate, breathing and temperature, and many babies settle fastest on a parent chest.
  • Smiles at this age are usually reflexive rather than social, and they often appear in sleep.
  • Responding to your baby quickly does not spoil them, it is how early trust gets built.

Sleep at 0 to 2 weeks

Newborn sleep is short, frequent and scattered across the whole 24 hours. Most babies this age total 14 to 17 hours, with some closer to 18, taken in stretches of roughly 2 to 4 hours around feeds. There is no day and night pattern yet because the body clock has not developed. Current safe sleep guidance is back sleeping every time, on a firm flat surface, with nothing loose in the sleep space.

SleepTypical range
Total sleep in 24 hours14 to 17 hours, sometimes up to 18
Longest stretchoften 2 to 4 hours
Sleep periods per day5 to 8, spread across day and night
Wake window30 to 60 minutes
Day and night rhythmnone yet, usually starts forming after 6 to 8 weeks

Feeding

Feeding sets the rhythm of these two weeks. Breastfed newborns commonly feed 8 to 12 times in 24 hours, roughly every 1.5 to 3 hours, and are usually not left longer than about 4 hours without a feed even overnight. Formula fed newborns often take 2 to 3 ounces every 2 to 3 hours, building up over the first month. Evening cluster feeding is common and does not on its own mean low supply.

Questions parents ask

How much should a newborn sleep in the first two weeks?
Most newborns sleep 14 to 17 hours across a 24 hour day, and some sleep closer to 18. It comes in short blocks of roughly 2 to 4 hours, because a newborn stomach empties quickly and needs refilling. Sleep is spread fairly evenly across day and night at this age. Variation is wide, and one baby total can sit well above or below another.
Is it normal for my newborn to only sleep 45 minutes at a time?
Short sleeps are common in the first two weeks. Newborn sleep cycles run around 45 to 60 minutes, and many babies surface fully at the end of one rather than linking into the next. Some stretches may be 3 hours and some 40 minutes, often on the same day. If your baby is feeding well and having enough wet nappies, short sleeps alone are not usually a concern.
How often should a 1 week old feed?
Breastfed babies usually feed 8 to 12 times in 24 hours at this age, roughly every 1.5 to 3 hours, counted from the start of one feed to the start of the next. Formula fed babies often take 2 to 3 ounces every 2 to 3 hours, with 8 feeds a day as a general minimum. Most guidance suggests not letting a newborn go beyond about 4 hours without feeding.
Can my newborn see me?
Yes, at close range. Most newborns focus best at about 8 to 12 inches, or 20 to 30 cm, which is roughly the distance from your face to theirs while feeding or being held. Beyond that, detail is blurry. Bold contrast and the shape of a human face hold attention more than colour, which is why your face is the most interesting thing in the room.
Why does my newborn startle and throw their arms out?
That is the Moro or startle reflex, a normal newborn response to a sudden noise, a movement or a feeling of falling. The arms fling wide and then curl back in. It is present at birth in healthy babies and usually fades over the first couple of months. Swaddling on the back can reduce how often it wakes a sleeping baby in the early weeks.

More questions about 0 to 2 weeks

The things parents actually search for at this stage. Tap any question to open it.

Is it normal for my newborn to grunt and squirm all night?
Very common. Newborns are noisy sleepers, and light sleep makes up a large share of their night, so grunting, snuffling, squeaking and wriggling often happen without waking. Many parents mistake it for distress. If your baby settles again on their own and feeds well, it is usually just newborn sleep. Persistent laboured breathing is different and needs checking.
Why does my newborn sneeze so much?
Sneezing clears tiny nasal passages of lint, mucus and dust, and newborn noses are very narrow, so it happens a lot. Frequent sneezing on its own does not usually mean a cold. Look at the whole picture instead. A fever, poor feeding or difficulty breathing alongside sneezing is worth a call to your doctor.
How do I know if my newborn is getting enough milk?
Output and weight are the two everyday signs. After day 5, most babies have at least 6 wet nappies a day, and they should be back to birth weight by around 2 weeks. Feeds that end with a relaxed, satisfied baby are another clue. If wet nappies drop or weight gain stalls, get feeding assessed rather than waiting.
Is it normal for a newborn to lose weight in the first week?
Yes. Most newborns lose 7 to 10 percent of their birth weight in the first days, largely fluid, and start gaining again from around day 5. Birth weight is usually back by two weeks and almost always by three. A loss beyond 10 percent, or no gain by the second week, is worth a same week review.
Why does my baby's breathing speed up and then pause?
Irregular newborn breathing is common, with faster runs followed by brief pauses of a few seconds, then a return to normal. The breathing centre in the brain is still maturing. Pauses longer than about 20 seconds, colour changes around the lips, grunting or flaring nostrils are different and need urgent medical attention.
Should I wake my newborn to feed at night?
Usually yes in these first weeks. Common guidance is to wake a newborn every 3 to 4 hours to feed until weight gain is clearly established, and not to leave them longer than about 4 hours even overnight. Once your doctor or health visitor confirms steady gain, most babies can be left to wake on their own.
How long does the umbilical cord stump take to fall off?
Usually somewhere between about 10 days and 3 weeks. It dries, darkens and detaches on its own, and keeping the area clean and dry is the standard advice. A little dried blood as it separates is common. Redness spreading onto the tummy, swelling, bleeding or foul smelling discharge needs same day medical attention.
Why does my newborn have tiny white or red spots on their face?
Newborn skin goes through several harmless phases. Tiny white bumps, small red blotches with a pale centre, and pimple like spots around two to four weeks are all common and usually clear without treatment. Skin also flakes and peels in the first week or two. Blistering, weeping spots or a rash with fever should be checked.
Is it normal that my newborn will only sleep on me?
Very normal. A newborn has spent months hearing your heartbeat, and your chest offers warmth, smell and motion that a flat mattress does not. Many babies protest being put down for weeks. Safe sleep guidance is still back sleeping on a firm flat surface, so contact naps are usually kept for times you are awake and alert.
Why does my newborn's skin look yellow?
Newborn jaundice is common and usually appears on day 2 or 3, then fades within one to two weeks. It happens as the body clears bilirubin left over from birth. Yellowing that appears in the first 24 hours, spreads to the arms and legs, deepens after the first week, or comes with sleepiness and poor feeding needs prompt assessment.
Can I spoil my newborn by holding them too much?
No. In the newborn period, responding consistently to crying is how a baby learns the world is predictable, and there is no evidence that holding a newborn creates bad habits. Being held often steadies breathing, temperature and heart rate. Whether you can hold them as much as you would like is a practical question, not a developmental one.
Why does my newborn's chin tremble when they cry?
A quivering chin, lower lip or trembling hands during crying is common in the first weeks, because the nervous system is still immature and signals overshoot. It usually stops when your baby is calmed or held. Trembling that continues while your baby is calm, or jerking that you cannot stop by holding a limb, should be checked promptly.
Is it normal for a newborn to have hiccups constantly?
Yes. Newborn hiccups are frequent, often after feeds, and most babies do not seem bothered by them. The diaphragm is still settling into a rhythm. They usually pass on their own within a few minutes. Hiccups paired with a lot of spitting up, arching or distress during feeds is worth mentioning at your next appointment.
How many wet nappies should a newborn have each day?
Roughly 2 to 3 in the first few days, rising to at least 6 a day once your milk supply is established after about day 5. Stools also change, moving from black meconium to green and then yellow over the first week. Fewer than 6 wet nappies a day after day 5 is a reason to seek advice.

When to check in with your doctor

Willo is a parenting companion, not a medical app. If something feels off, ask.

  • A temperature of 100.4°F (38°C) or higher in a baby under 3 months needs urgent medical assessment, at any time of day or night.
  • Fewer than 6 wet nappies a day after day 5, no wet nappy for 8 hours, a sunken soft spot, or a baby who is too sleepy to rouse for feeds.
  • Yellowing that starts in the first 24 hours, spreads to the arms and legs, deepens after the first week, or comes with poor feeding and drowsiness.
  • Fast, grunting or laboured breathing, pauses in breathing, or a blue, grey or blotchy colour to the lips, tongue or skin. This needs emergency help.
