WHY SLEEP TRAINING FAILS?



WHY SLEEP TRAINING FAILS?

You have followed a sleep-training method, tried to stay consistent, and waited for bedtime to become easier. Yet your child still wakes repeatedly, takes a long time to settle, or becomes distressed as soon as bedtime begins.

After repeated nights of broken sleep, it is understandable to feel exhausted and desperate for something that works.

The problem, however, may not be the method itself. Sleep training addresses specific behavioural sleep difficulties, and it cannot fix every reason a baby or young child struggles to sleep.

The Main Reason Sleep Training Fails

Behavioural sleep interventions can improve sleep for many children. Approaches such as the Ferber method and the fading method may help with specific sleep problems.

But no single technique addresses every sleep problem. If a child is rocked completely to sleep and needs the same help after every night waking, changing that sleep-onset association may help. If the child simply is not ready to sleep at the bedtime being attempted, repeatedly changing the parental response to crying does not address the timing problem.

Using The Right Tool for the Right Sleep Problem

Crying it out is a good example of how the right sleep-training method may not work when it is used for the wrong sleep problem.

• What It Is Designed For: Crying it out teaches a child to fall asleep independently at bedtime and return to sleep between sleep cycles without parental help.
• Why It May Not Work: If a child’s sleep difficulty has another cause, such as an unsuitable bedtime or nap schedule, crying it out will not address that issue. It may seem to help for a few nights before the sleep difficulty returns.
• How to Read the Results: If cry it out is being used for the right sleep problem and is followed correctly, the approach may help improve sleep within one night. If it doesn’t, it may signal a different sleep problem affecting the child’s sleep.

Common Implementation Mistakes: Why Sleep Training Is Not Working

Sleep training may not work as expected due to:

1. Mixing Methods

Don’t mix sleep-training methods once you have started. For example, starting with Ferber and then switching to crying it out can confuse the child because the response to their crying changes mid-process. This inconsistency can lead to more crying and distress.

2. Too Much Interaction With the Child

With Ferber’s controlled crying method, parents check on their child at set intervals without talking, picking them up, or helping them fall asleep. Too much interaction during these check-ins can make the process less clear for the child. Keeping each check-in brief and consistent helps avoid sending mixed signals about what is expected at bedtime.

3. Expecting Results on a Fixed Timeline

Different sleep-training methods take different amounts of time to show results. Expecting a method to work sooner than it can may make progress feel slower than it is.

Sleep Training Methods Compared

The comparison below outlines the expected timelines and key differences between these methods.

Method	How it Works	Age Range	Typical Duration	What It Addresses	Limitation
Extinction or Crying It Out Method	The child is put to bed, and the parent does not respond to crying until the next scheduled sleep period.	Under 15 months	Typically 1-2 days	Falling asleep and returning to sleep independently	Difficult for the parents on the first day
Ferber’s Controlled Crying Method	Parents put the child to bed awake and check in at gradually increasing intervals when the child cries.	16 weeks to 9 months	Typically 7-10 days	Independent sleep with scheduled check-ins	Check-ins can confuse the child if overdone
Fading Method	Parents gradually reduce the amount of help they provide while the child learns to fall asleep independently.	No specific age	At least 6 weeks or longer	Gradually reducing parental assistance	Requires high consistency

Extinction or Crying It Out (CIO) Method

This is the fastest of the three training methods. It generally takes about 1-2 days, depending on the child’s age, with the sleep association expected to change in about one day for children under 12 months and two days for children over 12 months.

The first night is usually the most difficult for parents because the child may protest longer. In the following days, there is typically less fussing and protesting. This method suits children under 15 months and is relatively simple to follow and implement.

Ferber’s Controlled Crying Method

This method was designed to reassure the parent while the child learns to fall asleep without the usual assistance. After the child starts protesting, the parent follows a strict timetable for check-ins. During each check-in, the parent does not talk to, pick up or assist the child, but simply checks on them before leaving again.

This can reassure parents because they can see their child during the process. However, too much interaction can send confusing messages to the child. This method is ideal for children between 16 weeks and 9 months and may involve 7 to 10 days of crying or protesting.

Fading Method

This method is promoted as a no-cry or very-low-cry method. Instead of removing parental assistance all at once, you gradually reduce the amount of help you provide when your child falls asleep.

A sleep association means that a baby becomes used to a particular form of assistance to fall asleep, such as feeding, patting or rocking.

If you have always rocked your baby all the way to sleep, for example, you might gradually rock for less time and put them in the crib drowsy but awake. If they become upset, you can quiet and soothe them using other methods. Each night, you do less of the work while your baby does more of it.

Progress with the fading method can be slow, requiring patience, stamina and consistency from parents. It can take at least 6 weeks and often around 3 months or longer to see improvement. The time it takes can also depend on the child’s temperament and how consistently you follow the plan.

Before starting, write down the plan you intend to follow. This gives you something to refer to each night and helps you stay consistent, rather than changing your approach partway through.

The Role of Parent Behaviour in Child Sleep

What happens around bedtime can influence how a child falls asleep and what they expect when they wake during the night.

• Falling Asleep Is a Learned Skill: Falling asleep independently is a skill children learn, and parents help them develop it through bedtime routines and the level of assistance they provide.
• Bedtime Assistance Can Affect Night Waking: Whatever helps a child fall asleep at bedtime may also be needed when they wake during the night. For example, a child who relies on rocking, feeding or patting to fall asleep may look for the same assistance after waking.
• Parents Can Influence the Sleep Pattern: Understanding how routines, responses and consistency affect a child’s sleep can help parents make informed changes rather than follow a sleep training myth that may not apply to their situation.
