Newborn sleep, 0–6 weeks: there is no schedule yet

You are six days in, nothing is predictable, and every article you find talks about routines. There is a reason none of them are working: the machinery that produces a routine has not switched on yet.

A newborn has no circadian rhythm. In the womb there is no day and no night, and the internal clock that eventually distinguishes them takes weeks to start running - melatonin production does not begin in any meaningful way until around eight to twelve weeks. Until then, sleep is distributed more or less evenly around the clock in stretches of two to four hours, driven almost entirely by hunger and the need for sleep itself.

This is not a phase to be managed into shape. It is the design, it is temporary, and the single most useful thing to know is that nothing you do in these six weeks will make a routine appear sooner.

What is worth doing

The safe sleep rules, which are not optional

Every sleep, day and night: on the back, on a firm flat mattress, in their own clear sleep space, with no pillows, duvets, bumpers or soft toys. Room-sharing with your baby in their own cot or basket for at least the first six months lowers the risk of sudden infant death substantially. Keep the room between about sixteen and twenty degrees, and keep the household smoke-free.

Never sleep with your baby on a sofa or an armchair - that carries a far higher risk than a bed. If you may fall asleep while feeding at night, it is safer to prepare your bed in advance according to safer-sleep guidance than to feed on the sofa hoping you will stay awake.

There is no routine to find yet. You are not missing it.

What not to bother with

Wake windows in the strict sense, sleep training of any kind, dream feeds as a strategy, capping naps, and any book promising a schedule for a three-week-old. None of these have anything to work with at this age, and pursuing them mostly produces a distressed parent.

One thing worth watching loosely: newborns become overtired quickly, and awake stretches of much more than forty-five to sixty minutes often end badly. If a baby is difficult to settle, having been awake too long is the most likely reason.

The one thing worth watching

Awake stretches. Newborns become overtired remarkably quickly, and a baby who has been up for more than about an hour is usually much harder to settle than one caught at forty minutes. There is no schedule to keep, but there is a limit worth respecting.

The signs are subtle at this age: a fixed stare, a turned-away face, jerky movements, a first small yawn. Crying and eye-rubbing come later and mean you have already missed it. If settling has suddenly become difficult when it was easy an hour ago, the awake stretch running long is the most likely explanation and it is worth trying before anything else.

Building the day–night distinction

The one thing that does useful work in these weeks costs nothing. Make daytime feeds bright, chatty and ordinary - curtains open, normal household noise, eye contact, conversation. Make night feeds dim, silent and dull - minimal light, no talking, straight back down afterwards.

It has no effect for the first few weeks because there is no clock to influence yet. But the distinction is what the clock latches onto when it starts running at around eight to twelve weeks, and babies whose nights have always been boring tend to sort themselves out sooner.

When to stop troubleshooting

Speak to your midwife, health visitor or GP urgently if your baby is very difficult to wake, is feeding poorly or refusing feeds, has fewer wet nappies than expected, is not regaining birth weight, has a fever, or seems floppy or unusually unwell. Newborn sleep varies enormously; feeding and alertness are the things worth watching closely.

General guidance, not medical advice. Your paediatrician's advice takes precedence.
