Signs Your Baby Is Ready to Sleep Through the Night
"When will she sleep through the night?" is the question every Australian parent asks by month two. The honest answer: there's a wide normal range, but the night you stop being woken is usually the night your baby learns to resettle through their natural partial wakes — not the night they stop waking at all.
The 6 signs your baby is ready
- Aged 4 months or older with weight gain on track.
- Past the 4-month sleep regression (sleep cycles have matured).
- Going down drowsy-but-awake at bedtime, at least sometimes.
- Spaced day feeds with full milk feeds rather than constant snacking.
- Brief overnight wakes where they thrash, mumble, then resettle alone.
- A consistent bedtime routine that ends with a clear sleep cue (e.g. a lullaby).
What "sleeping through" actually looks like
Even adults wake 4–6 times overnight between sleep cycles — we just don't remember because we resettle in seconds. The goal for your baby isn't zero wakes; it's independent resettles. The shift you'll notice is going from "she woke me up 4 times" to "she woke up 4 times and I didn't hear her."
The on-loop lullaby setup
Download the 60-minute loop of your personalised lullaby and let it play softly through the first sleep cycle (40–50 minutes). When baby partially wakes between cycles, the familiar song is still there — same name, same melody, same parent voice greeting — and the recognition cue triggers resettling before a full wake-up develops.

When to talk to your GP or child health nurse
If your baby is over 6 months, otherwise healthy, and still waking every 1–2 hours, it's worth a check-in. Iron levels, reflux, and undiagnosed sleep apnoea all show up as fragmented sleep and are very treatable.

Frequently Asked Questions
What age do babies typically sleep through the night in Australia?
Most healthy babies are physiologically capable of a 6–8 hour stretch from around 4–6 months, with consistent 10–12 hour nights becoming common between 9 and 12 months. There's a huge normal range.
What does 'sleep through the night' actually mean?
Sleep researchers usually define it as a 5–6 hour stretch — not 12 hours of total silence. Most adults wake briefly 4–6 times per night too; we just resettle ourselves.
What are the signs my baby is ready?
Weight gain on track, 4–6 month milestone reached, dropping the third nap, and self-settling at bedtime even briefly. The single biggest sign is partial-waking and resettling without your help.
Does a personalised lullaby help babies sleep through?
Yes — when used as an on-loop cue during partial wakes. Babies wake briefly between sleep cycles; the familiar lullaby still playing tells them 'still bedtime' and they resettle without crying out for you.
Will night feeds stop on their own?
Usually yes, between 6 and 12 months, once daytime calories are sufficient. Talk to your GP or child health nurse before deliberately dropping night feeds under 6 months.
