How much should a 1-month-old sleep?

Fourteen to 17 hours in total each day. About 8 to 9 hours happen at night, interrupted by feeds, and the rest is spread over 4 to 5 daytime naps that are still very irregular in length. Some babies land at the bottom of that range and some at the top. Look at the day as a whole and at how your baby seems, rather than trying to hit an exact number.

Why does my 1-month-old only sleep in my arms?

Because motion, warmth and your heartbeat are what your baby knew for nine months, and at 1 month there is no expectation of self-settling. Contact naps are normal and not a habit you'll regret. If you want to shift some sleep to the crib, try putting your baby down drowsy but awake once a day when they are calm, and let the rest happen in arms. Always move them to a safe flat surface if you feel sleepy yourself.

Should I still swaddle at 1 month?

Many babies settle better swaddled at this age, with the arms snug and the hips loose so the legs can bend. The hard rule is timing: stop swaddling as soon as your baby shows any sign of rolling, usually somewhere between 2 and 4 months, and never swaddle a baby who sleeps on their side or front. Ask your pediatrician to check your technique if you are unsure.

When will my 1-month-old sleep through the night?

Not yet, and that's expected. At 1 month babies still need night feeds, and the 8 to 9 hours of night sleep come in pieces. Longer stretches usually build gradually over the coming months as the body clock matures and feeds space out. Chasing it now, with long gaps between feeds or cereal in a bottle, is not safe. Talk to your pediatrician about feeding intervals if you are worried.

Baby sleep schedule at 1 month: wake windows, naps and night feeds

At 1 month your baby still needs 14 to 17 hours of sleep across the day, with about 8 to 9 of those at night — still broken by feeds — and 4 to 5 naps filling in the rest. The visible change from the first weeks is the awake time: wake windows now stretch to 45 to 75 minutes.

That extra half hour buys your baby time to look at your face, track a high-contrast pattern and start responding to you. It also makes it easier to overshoot. The end of every wake window should get quieter than the start, so your baby arrives at the crib winding down rather than revving up.

Wake window

The day-night rhythm is still immature at 1 month. Melatonin production has not settled into a cycle yet, so long organized nights aren't on the table. If the longest stretch of sleep lands in the late afternoon and the 4 am shift is wide awake, nothing has gone wrong — the internal clock simply hasn't switched on. Morning daylight is the single most useful nudge you can give it.

What has changed is how present your baby is. Eye contact holds longer, your voice gets a reaction, and the first real social smile often appears this month. Use the fresh part of the wake window for that, and keep the last stretch calm. Evening fussiness is also common now — a long unsettled patch before the night — and it's usually cumulative tiredness rather than anything you did.

A sample day

At 1 month the day is still built around feeds rather than a clock. Use the sample below as a picture of how 4 to 5 naps and 45 to 75 minute wake windows can fall, and shift the times freely to fit your baby.

Time	What happens
7:00	Wake-up and first feed
8:00	Nap 1 · approx. 45 min
10:00	Nap 2 · approx. 60 min
12:30	Nap 3 · approx. 45 min
14:30	Nap 4 · approx. 60 min
16:45	Nap 5 · approx. 30 min
20:00	Bedtime routine and lights out

A sample day to give you a rough idea — every baby is different. Adjust the times to your child's sleep cues, and talk to your pediatrician about anything that worries you.

Tips for this age

Back to sleep for every nap and every night — including when grandparents or a sitter do the settling; there is no exception to the position.
Keep the crib empty: no loose blankets, pillows or soft toys before 12 months. A correctly sized sleep sack is the warm option.
Get outside or open the blinds in the morning, because natural light is the strongest signal you can give an immature body clock.
Wake windows are not all equal — the first of the morning is usually the shortest — and a few days of logging in Lulla will show you your baby's own pattern.
If evening crying is inconsolable, keeps escalating, or comes with feeding trouble or fever, have your pediatrician take a look rather than assuming it is just colic.
