How to get your baby to sleep through the night

What “sleeping through the night” really means

Every person — adults included — wakes briefly between sleep cycles. A baby who “sleeps through the night” is not a baby who never wakes; it is a baby who can surface, settle and drift back into the next cycle without needing you to feed, rock or replace a dummy every time.

So the goal is not to stop your baby waking. It is to change what needs to happen when they do.

When can a baby sleep through the night?

From around 16 weeks, babies have the ability to link sleep cycles and sleep for longer, uninterrupted stretches if all their needs are met. If your baby was premature, count from their due date, not their birth date.

A small percentage of babies at 4–6 months still need one night feed. Generally, though, they can consolidate night sleep into two long stretches with a single feed in the middle of the night. Always check with your clinic sister or paediatrician that your baby is growing well before you drop night feeds.

A step-by-step plan for longer nights

1. Fix the bedtime. Pick a consistent bedtime that suits your baby’s age (often between 18:00 and 19:30) and keep it the same every night, weekends included.
2. Start a 30–45 minute bedtime routine. Close the curtains, warm bath, massage, pyjamas, a story or song, then a feed. Keep it in the same order every night so your baby learns what comes next.
3. Move the feed earlier in the routine. If your baby falls asleep on the breast or bottle, that becomes their sleep association — the thing they need to fall back asleep at 2am. Feed earlier in the routine, with the lights on, so they finish the feed awake.
4. Put your baby down drowsy but awake. Let them do the last little bit of falling asleep themselves, in their own cot. This is the single most important skill for sleeping through.
5. Get the room right. As dark as possible (melatonin is released in darkness), 19–22 °C, fresh air during the day, and white noise to mask sudden household sounds. Remove mobiles and toys from the cot.
6. Check daytime sleep. An overtired baby sleeps worse at night, not better. Make sure naps are happening at the right times for their age (see our sleep schedule by age guide).
7. Respond consistently at night. Decide in advance how you will respond to wakings — and respond the same way every time. Consistency is what helps a baby learn.
8. Give it two weeks. New habits take time. Most families see real change within one to two weeks of consistent practice.

Common reasons babies keep waking at night

• Falling asleep while feeding, being rocked or held — then needing the same help between sleep cycles.
• Overtiredness from naps that are too short or too far apart.
• A bedtime that is too late, or that moves around from night to night.
• A room that is too light, too warm or too noisy.
• Hunger from too little milk or food during the day (check with your clinic first).
• Developmental leaps, teething or illness — these are temporary; return to your routine once your baby is well.

Does sleeping through the night mean leaving my baby to cry?

No. At Momslifeline we never allow a baby to cry for longer than 3 minutes without seeing, feeling or hearing their parent. Some protest is normal when you change a habit — crying is how babies communicate — but your baby is never left alone with it. Read more in our guide to gentle sleep training without cry it out.

When to get help

If you have been consistent for two to three weeks and nothing is changing, if your baby is waking every one to two hours, or if you are simply too exhausted to work out a plan, a personalised consultation can save weeks of trial and error. Erica reviews your baby’s full routine, temperament and history and gives you a written, step-by-step plan for your family — with support while you put it into practice.
