A Guide to Sweet Dreams for Your Baby

Most baby sleep advice is written as troubleshooting — what to do when it has gone wrong. This is the other half: what to put in place before that, so that the room, the routine and the timing are all working in the same direction. None of it guarantees a baby who sleeps through, because nothing does. It removes the causes you have control over.

The non-negotiables first

Everything else in this post is preference. This part is not, and it is worth stating plainly because it is also the part that gets quietly eroded by tired improvisation at 3am.

On the back, every sleep, until they can roll both ways reliably on their own. Naps included — side and front sleeping carry the higher risk.
On a firm, flat, separate surface. A cot, crib or moses basket with a firm mattress. Not a sofa, not an armchair, not a propped incline.
Clear cot. No pillows, no duvets, no bumpers, no soft toys and no loose blankets in the first year.
Feet to foot if you use a blanket at all, tucked no higher than the shoulders — or skip the question entirely with a sleep sack.
Smoke-free, and not overheated. Overheating is a recognised risk factor, and in a warm climate it is the easier mistake to make.
In your room for the first six months, on their own surface.

The reason a sleep sack solves several of these at once is that it cannot be kicked off, cannot ride up over the face, and takes the blanket decision out of the room. What weight to choose is a separate question, and one our sleep sack and TOG guide answers properly.

The room

Temperature. Aim for roughly 16–20°C where that is achievable; in a warm climate, focus on whether the baby's chest feels comfortably warm rather than chasing a thermostat number. Hands and feet run cool and tell you nothing.
Dark. Properly dark for night sleep, and dark for naps too once past the newborn weeks. Light is the strongest signal the body clock has, and a bright room is doing work against you.
Sound. Steady, low white noise can help mask a household — but keep it low, well away from the cot, and turn it off once the baby is asleep if you can.
Boring. A cot is for sleep. Mobiles, lights and projectors give a baby something to do at 5am.
Airflow. Moving air is more comfortable than still air at the same temperature. A fan pointed at a wall rather than at the baby is usually the right compromise.

A bedtime routine you will actually keep

The single most common mistake is building a routine that works beautifully on a calm Sunday and collapses on a Wednesday. Aim for twenty to thirty minutes, four or five steps, in the same order every night. Same order matters more than same content — the sequence is the signal.

Bath or a warm wipe-down. Optional, and not every night; the mild drop in body temperature afterwards is the part that helps.
Into sleepwear, in the room where they will sleep, with the lights already low.
A feed — but not the last step, once you are past the newborn weeks.
One quiet thing: a book, a song, a few minutes of nothing.
Into the cot, awake if you can manage it, with the same short phrase every night.

The order puts the feed before the final step deliberately. A baby who always falls asleep on the breast or bottle learns that this is how sleep starts, and will reasonably expect it again at the next wake-up. That is not a moral failing and plenty of families are happy with it — but if you would like an alternative later, it is much easier to leave the door open now than to close it and reopen it at eight months.

Drowsy but awake, honestly

This is the most repeated instruction in baby sleep and the most quietly infuriating, because for a large minority of newborns it simply does not work — they wake fully the moment they touch the mattress. If that is your baby, do not read it as a failure. Try it once a day at the easiest sleep of the day, usually the first nap, and let the rest be whatever gets everyone through. Most babies become far more capable of it somewhere between three and five months, when sleep architecture matures.

Timing beats technique

If bedtime is a fight, the cause is more often the schedule than the routine. A baby who has been awake too long arrives at bedtime with a stress-hormone surge that makes settling harder, not easier — the wired, giggly, impossible-to-put-down state most parents recognise. Bring bedtime earlier rather than later, and watch the last awake window of the day more carefully than any other. There is a full table of comfortable awake windows in our guide to whether a baby is getting enough sleep.

What not to buy

Cot bumpers, in any material, including the mesh ones. No safe-sleep body recommends them.
Sleep positioners and wedges. These are specifically warned against.
Weighted sleep sacks and weighted swaddles. Not recommended for infants.
Anything that requires a baby to sleep on an incline.
Movement or oxygen monitors bought for reassurance. They are not shown to reduce risk, and false alarms cost more sleep than they save.

Questions parents ask

When should I start a bedtime routine?

Any time from around six to eight weeks, when a rough day-night rhythm starts to appear. Before that a routine does no harm, but it also has little to work with — newborn sleep is driven by feeding and by an immature body clock rather than by cues.

What temperature should a baby's room be?

Roughly 16–20°C is the usual guidance. In a warm climate that is often not achievable, so judge by the baby instead: a chest or back of the neck that feels comfortably warm and dry is right. Sweating, damp hair or flushed cheeks mean too warm.

Is white noise safe for babies?

Used sensibly, yes. Keep the volume low — conversational rather than loud — position it well away from the cot rather than beside it, and switch it off once the baby is settled where you can.

Can my baby sleep with a comforter or soft toy?

Not in the first year. Keep the cot clear of soft objects, loose bedding and toys until at least twelve months, after which a small comforter is generally considered fine.
