Baby sleeps all day and is awake at night

Newborns spent nine months in a body that was still at night and moving all day. Their internal clock arrives late, and it can be nudged.
Why it happens
Newborns are not born with a body clock. The circadian rhythm that separates day from night develops over the first two to three months, and melatonin production does not properly begin until around eight to twelve weeks.
In the womb, the mother's movement through the day tended to lull the baby to sleep, and the still hours of the night were when the baby was most active. Many babies simply arrive on that schedule.
Newborns also sleep in short cycles of two to four hours around the clock regardless, so the aim is not to make a newborn sleep through — it is to shift the longer stretches into the night.
It usually resolves by around six to eight weeks with no intervention at all. What follows below shortens it rather than being essential.
How to shift it
Make daytime bright and noisy. Feed near a window, keep normal household sound going, and do not tiptoe. Daylight is the strongest signal the developing clock responds to.
Make night boring: dim light, no talking beyond the minimum, nappy changes only when needed, and straight back down. The contrast between day and night is what teaches the difference.
Cap daytime naps. If a stretch goes beyond about three hours in the day, wake them for a feed. It feels wrong and it is how the pattern turns around.
Feed frequently in the day, so the biggest calories are not being taken at 2 a.m.
Get outside, or at least onto a balcony, in the morning. Ten minutes of daylight does more than an hour of indoor light.
Start a very short evening routine early — bath or wipe-down, feed, dim room — even at three weeks. It does nothing tonight and everything by week eight.

Getting through it
Sleep when the baby sleeps is impractical advice for most Indian households, but sleeping in shifts is not: one parent takes until 2 a.m., the other after. Even one four-hour unbroken block changes how a person functions.
Accept help with the daytime rather than the nights if that is what is on offer — a nap in the afternoon while someone else holds the baby is worth more than company at 3 a.m.
Keep safe sleep non-negotiable however tired you are: the baby on their back, on a firm flat surface, with nothing else in the sleep space. The riskiest moment for an exhausted parent is falling asleep holding a baby on a sofa or armchair, which is far more dangerous than a bed.
If you feed lying down, set the bed up safely for it in advance rather than improvising at 3 a.m. — firm mattress, no pillows or covers near the baby, nobody who has drunk alcohol or taken sedating medication.
When to see a doctor
Same-day care for a newborn who: is difficult to wake for feeds, is feeding poorly, has fewer wet nappies than expected, is jaundiced, has a fever, or is unusually floppy. Sleeping excessively in a newborn is not always benign.
Also for a baby who cries inconsolably for hours, arches and appears in pain, or vomits forcefully after feeds.
See your own doctor if the exhaustion is tipping into low mood, hopelessness or anxiety that will not settle — postnatal depression is common and treatable, and sleep deprivation makes it far more likely. Tele-MANAS on 14416 is free, confidential and round the clock.

Frequently asked questions
How long does day-night confusion last?
Usually resolving by six to eight weeks. Bright days and dark boring nights speed it up.
Should I wake a sleeping baby?
In the daytime, yes, if a stretch runs beyond about three hours in the early weeks. At night, only if your doctor has asked you to for feeding or weight reasons.
Is it safe to let a newborn sleep in a bright room?
Yes, and it helps. Daytime naps do not need darkness in the first weeks.
Can I use a jhula or swing to settle them?
For supervised settling while awake, yes. Babies should not be left to sleep unsupervised in a swing, jhula, car seat or bouncer — the position can compromise breathing.
