Before any of the steps in this handbook will work, your child has to be developmentally ready for them. Most aren't ready before 6 months. Some need longer. Here's how to tell.
\nThe approach in this handbook is structured and responsive - not cry-it-out.
\nThe structured seven-stage programme works best for children around six months and older. This is not an arbitrary cutoff. Before six months, a baby's sleep cycles are still consolidating, feed needs are higher and harder to predict, and a child is not yet developmentally able to learn new sleep associations that will stick.
\nSome paediatric sleep resources discuss the four-to-six-month window as developmentally suitable for many families. This handbook uses a more conservative six-month corrected-age gate, because that's when the neurological change supporting habit formation typically appears.
\nIf your child was born before 37 weeks, use their corrected age (chronological age minus the number of weeks they were early) when reading the gate above. A baby born at 35 weeks is, at eight calendar months, developmentally closer to six months. The six-month gate refers to corrected age, not birth date. Use corrected age for at least the first two years.
\nIf your child is younger than four months, the structured programme is not ready for you yet. Skip to What to do if your child is under four months below.
\nReady is not just age. Ready is a constellation of seven conditions. Your child should ideally show six of these seven. If your child shows four or five, wait two to four weeks and reassess. If your child shows three or fewer, the structured programme will be harder than it needs to be.
\nIf your child is over 12 months, items 3 (feeding) and 4 (acute illness or recent vaccination) read differently - toddler feeding rhythms aren't on a 3–4 hour clock, and a single tooth or a cold is not the same disqualifier as it is in the first year. The principle is the same: stable rhythm, no acute disruption, ahead of you. See the toddler and preschool chapter for age-specific equivalents.
\nYour child has developed a loose pattern of roughly when they wake, when they seem tired, and when they sleep. The pattern doesn't have to be exact - it can shift by thirty to forty minutes day to day - but it should be recognisable. If your child is sleeping at completely random times and waking unpredictably, the sleep system hasn't consolidated enough yet.
\nAt least some of the time, you can place your child in the cot in a calm-but-awake state and they will either fall asleep on their own or settle without escalating immediately. This doesn't mean they do it every time. It means they can. If your child escalates to high-distress the moment they leave your arms, they are not yet developmentally ready.
\nFeeds are roughly predictable - perhaps every three to four hours during the day, with a pattern to night feeds that is recognisable. Your paediatrician is satisfied with weight gain. There are no active feeding concerns (reflux, suspected allergies, weight worries, poor latch). If feeding is still chaotic or your paediatrician has flagged concerns, settle the feeding question first.
\nStart the programme when your child is well and not in the window of post-vaccination soreness or fever. If your child is cutting a tooth, recovering from a cold, or uncomfortable for any medical reason, wait until the acute thing has passed and two to three days of wellness have returned.
\nA recent house move, new caregiver, new sibling, new daycare, or parental absence can throw the sleep system temporarily out of sync. If a big change has happened in the last two to three weeks, wait until your child has settled into the new rhythm.
\nYour paediatrician has not identified a medical condition that would interfere with sleep learning - such as reflux, suspected sleep apnea, suspected food allergy, or a neurological flag that affects regulation. If your paediatrician is watching something, address it before starting.
\nYou can hold a consistent approach for two to four weeks. Life will still happen - this is about not starting the week you go back to work or move house. Consistency is the biggest predictor of success.
\nCount the signs above that are true for your child.
\nThe conditions are right. A structured plan is likely to work cleanly. The seven-stage programme in the full handbook walks you through it over two to six weeks.
\nReady to start? Buy the handbook - $15 USD, or read the free sample chapter first.
\nTwo to four weeks of groundwork will make the structured work much easier. The Before readiness section below walks through what to do during the wait. Come back and re-check at the end.
\nTwo paths here, and the difference matters:
\nIf your child is under six months, a low score is usually just developmental - they aren't ready for the structured programme yet, and that's normal. Read the Under four months or 4–6 month window section below for what to do now, and come back to re-check in a few weeks.
\nIf your child is six months or older and still scoring three or fewer, something else is likely going on - feeding, medical, environmental. Speak to your GP, health visitor, or paediatrician. The Paediatrician flags section below lists what to discuss first.
\nSee Next steps at the foot of the page for the matching action based on your score.
\nThe principles of this handbook - the mantra, the calm presence, the room set-up, the routine, the basic wake-window awareness - are good practice from birth. They will not trigger learning in a baby under six months the way the structured programme will, but they lay groundwork and make the transition easier when readiness does arrive.
\nThe calm presence. From day one, your calm is your child's regulatory mirror. When you are steady, your child can borrow that steadiness. This is co-regulation - not something you have to earn or teach, but something your child is wired to sense. If you find yourself unable to stay calm - if the crying is triggering panic or rage in you - Looking after yourself has support for that. But the simple act of breathing steadily near your settling child, of making your body unhurried, does work from the first week.
\nThe mantra. A simple, repeated phrase you say during settling - "I'm here, you're safe, I've got you" or something that fits your family - gives your child something consistent to anchor to. It is not a magic word. It is a signal that this moment is familiar, and you are still present. Start using it from whenever feels natural. It costs nothing, and it makes the transition to the structured programme much smoother.
\nThe room. A dark, quiet, cool space with a sound machine and a sleep light is good sleep hygiene from birth. If your child sleeps in a bright room or next to the television, dimming the light costs nothing. A basic white-noise machine is inexpensive. These changes will not solve broken sleep in a newborn, but they remove barriers to sleep when a child is ready to learn.
\nWake-window awareness. Newborns have short wake windows - as little as thirty to forty-five minutes at two months, building to seventy-five to ninety minutes by four months. The single most common unforced error parents make is trying to settle a baby who is not yet tired enough. Learning to read your child's tiredness cues rather than watching the clock is useful from the start, and it makes the structured programme work better later.
\nA simple routine. A bedtime routine need not be elaborate. Bath, feed, sleep light on, mantra, into the cot. Five to ten minutes is enough. A predictable sequence signals to your child's nervous system that sleep is coming. This is good practice from birth, and it becomes the foundation for the structured programme.
\nNone of these elements require your child to be ready for habit change. They are simply good sleep hygiene. They work alongside whatever your child's sleep currently looks like, and they make the transition to the structured programme far cleaner when readiness does arrive.
\n\nIf your child is younger than four months, the structured seven-stage programme is not a framework designed for this age. This is not because something is wrong. It is because the neurological readiness is not there yet.
\nWhat to do instead:
\nThe Foundations chapter covers the under-six-months period in more depth, including how to understand your newborn's sleep patterns, how to avoid common early mistakes, and what to do if sleep feels disorganised or distressing.
\nIf your child is between four and six months, they are in a bridging phase. They may be ready to start; they may not be. Use this section to prepare for readiness and get a sense of timing.
\nAt four to five months, focus on these things:
\nAt five to six months:
\nIf readiness is approaching, you can use these weeks to consolidate the foundations. Your child has probably already experienced being put down drowsy, settling with your voice nearby, and the basic mantra. The structured programme will build on these baseline expectations rather than introducing them cold.
\nBy six months, if your child checks at least six of the seven readiness signs, the structured programme is more likely to run smoothly. You can move into the seven stages with confidence.
\nBefore starting the structured programme, talk to your paediatrician if any of these apply to your child:
\nIf you and your child share a bed, this programme as written isn't for you. The structured seven-stage progression is built around a separate sleep space - cot, bassinet, or bedside sleeper - and most of the stage mechanics (the sleep spot, the response ladder, stepping back the touch) assume you are leaving the room or moving away while your child stays in their own space.
\nThat isn't a judgement about bedsharing. It is a description of what this handbook teaches. If you bedshare safely and intend to keep doing so, the structured stages won't fit your setup. Some of the principles still carry over and may be useful regardless: the mantra, the calm presence, the room cues, and the response ladder all work whether you sleep in the same bed or not.
\nIf you are transitioning from bedsharing to a separate sleep space and want to use this handbook for that transition, the cot-to-bed and bedroom-transition guidance in the toddler and preschool chapter is the closest analogue. Establish the new sleep space first, give your child a week or two to settle into it, then come back and start at Stage 1.
\nFor safe-bedsharing guidance - the conditions under which bedsharing is and is not safe - the Lullaby Trust and Basis (Baby Sleep Information Source) maintain detailed, evidence-based advice. This handbook does not duplicate that work.
\nIf your child is eighteen months, two years, four years, or older, and you are reading this handbook for the first time, the answer is usually yes: most older children adapt to this handbook's approach with stage-appropriate adjustments. The structured programme was designed around younger babies, but the principles scale.
\nOlder children take a different shape of work. They have language, which means more communication and negotiation. They have memory, which means they may remember a previous method you tried. They have independence, which means some of the stages work differently (the sleep spot is now a visible boundary you can discuss; the "no touch" steps involve talking rather than silence). The seven stages chapter and the toddler & preschool chapter cover age-specific adjustments.
\nDon't worry that you've "missed the window." There is no fixed window. Older children can still learn new sleep patterns when you start. Adjust the approach to your child's developmental stage and you are still on the right path.
\nThis checklist isn't medical advice. The full safety note covers when to stop and talk to a doctor first.
\nIf you scored six or seven, the structured programme is the next step. Many families notice early signs of progress in the first week, with the full programme running about two to six weeks. Two ways in:
\nIf you scored four or five, use the next two to four weeks for the groundwork in the Before readiness section. Bookmark this page and come back to re-check. While you're waiting, the free sample chapter is a good place to start the reading.
\nIf you scored three or fewer, the next call is your GP, health visitor, or paediatrician - not this handbook. The Paediatrician flags section lists what to flag for them.
