Sleep Training Approaches Compared

What we are actually comparing

"Sleep training" covers a family of behavioural approaches that differ mainly in how much parental presence and response they involve. Described neutrally, and without endorsing any of them:

• Extinction, commonly called cry it out. The baby is put down awake and the parent does not return until morning, other than for genuine needs.
• Graduated extinction, associated with Richard Ferber. The parent returns at timed intervals that lengthen across the night and across successive nights.
• Chair method or gradual retreat, sometimes called camping out. The parent stays in the room and moves progressively further from the cot over a period of nights.
• Pick up, put down. The parent lifts and settles the baby whenever they cry, then returns them to the cot awake.
• Bedtime fading. Bedtime is moved to when the baby actually falls asleep, then shifted earlier in small steps.

Those names come from the parenting literature, not from clinical guidance. That distinction turns out to matter.

What health services actually publish

The NHS

Publishes no sleep training method. Its guidance on baby sleep covers routines, day and night contrast, coping with disturbed nights and sharing the load, and ends with the referral line: "If your baby is having problems sleeping or you need more advice about getting into a routine, speak to your health visitor."

NICE

Its postnatal care guideline, NG194, is the relevant UK clinical guidance for the first weeks. It contains recommendations on safer sleep and on bed sharing. It contains no recommendation on behavioural sleep interventions for babies.

The AAP

Comes closest to endorsing an approach without naming one. For babies four months and older it advises putting them down drowsy but awake, and then: "Do not rush in to soothe a crying baby. Babies need time to put themselves back to sleep, and they need to learn how to fall back asleep on their own. It is normal for a 6-month-old to wake up during the night and then go back to sleep after a few minutes." The same page immediately qualifies that, and the qualification matters as much as the advice: "Of course, you can attend to them—like feeding them, changing a dirty diaper or comforting them if they are sick—if needed." Its toddler bedtime guidance goes further, advising parents to "avoid returning to your child's room when they call out", on the reasoning that "children's main goal is to get you to appear".

Red Nose Australia

Says the opposite. In its bedtime routine guidance: "We recommend a hands-on settling technique for an upset child. Never leave a crying child. Stay with them so they know that they are safe and help support them to sleep."

The HSE in Ireland

Sits between the two and is the only one to describe a method. For night waking it advises "try not to leave them crying for longer than a few minutes", and to hold and soothe them, feed them if hungry, and return them to the cot drowsy but awake. It also names a technique: rocking and back-rubbing can become sleep associations between six and twelve months, and "when your baby is 6 months old, you can start to phase these out using the gradual retreat approach."

Where that leaves you

Two of the four bodies give advice that cannot both be followed. "Do not rush in to soothe a crying baby" and "never leave a crying child" are not nuances of the same position. They reflect genuinely different judgements about the same thin evidence, made by organisations that are each reputable in their own country.

What they do agree on is narrower and more useful. Every one of them recommends putting a baby down drowsy but awake from around three to four months. Every one of them treats waking in the night as normal at every age in the first year. None of them recommends any approach before three months. And none of them endorses a named commercial programme, an app, or a consultant's protocol.

What is and is not established

Established: babies wake between sleep cycles, and where they fall asleep affects how easily they settle again. That is why drowsy but awake is the one piece of advice with universal agreement.

Not established, at least not to a standard any of these bodies has been willing to publish: that one named method outperforms another; that a specific interval schedule matters; that a particular age is the correct age to start; or that any approach produces lasting differences in a child's sleep years later. Where you see confident claims on those points, check whether the source sells something.

The Lullaby Trust adds a safety boundary that applies whatever you decide. Products and advice promising longer or deeper sleep "can actually be dangerous as it can affect your baby's ability to wake up if they need to", and it names impaired arousal as a SIDS risk factor. Behavioural approaches change how a baby settles. Anything that changes how easily a baby can wake is a different category of thing entirely.

Practical ground rules if you decide to try something

Safer sleep does not pause for sleep training. Back to sleep, own clear flat firm sleep space, same room as you for the first six months, room at 16 to 20°C by the Lullaby Trust's guidance, and cot kept clear. Do not start during illness, teething pain or immediately after a house move, since every service notes these disrupt sleep independently. Rule out hunger first — the HSE says to feed a hungry baby at night, without qualification. Give any approach more than a couple of nights before judging it, and stop if it is making things worse for you or your baby. And tell your health visitor or public health nurse what you are doing; they see this constantly and will not be shocked.

When to ask

Speak to your health visitor, public health nurse or GP before starting anything if your baby was born prematurely, has reflux, has a medical condition, or is not gaining weight. Speak to them regardless if bedtime has become distressing for you, if you are struggling to cope with the broken nights, or if you feel low and unable to enjoy things. That is a reason to see a GP in its own right, and it is far more common than most people are told.
