Does Your Baby Really Need to Learn to Fall Asleep Independently to Sleep Through the Night?
Does Your Baby Really Need to Learn to Fall Asleep Independently to Sleep Through the Night?
If you’ve spent any time reading baby sleep advice, you’ve probably heard some version of this:
If your baby needs you to get to sleep at bedtime, they’ll need you every time they wake overnight.
Therefore:
Teach them to fall asleep independently at bedtime and they’ll learn to put themselves back to sleep overnight.
It sounds logical.
And there’s research showing that babies who fall asleep independently are also more likely to return to sleep without signalling for their parents during the night.
But here’s the important bit:
A correlation finding like this doesn’t necessarily tell us which thing caused the other.
First, almost all babies wake overnight
This gets lost in conversations about “sleeping through”.
Studies using recording devices instead of relying only on what parents remember in the morning have found that most babies wake during the night, including babies whose parents think they sleep through.
But some babies wake, wriggle around for a bit and drift back to sleep.
While others wake and immediately make it very clear that parental assistance is required.
So sometimes “my baby sleeps through” really means:
“My baby wakes, but doesn't call me.”
Which is an important distinction - so put a pin in that.
The research does find a link between falling asleep independently and settling independently overnight
Babies who are routinely put down awake are more likely, on average, to have periods of waking overnight in which they return to sleep without parental involvement.
And behavioural sleep interventions that encourage independent settling can improve sleep for some infants and families. Randomised trials have found reductions in sleep latency, night waking and parent-reported sleep problems following behavioural interventions.
So the relationship isn't imaginary.
But where things become a bit less certain is why these babies settle independently.
What if some babies are simply more inclined to do both?
Imagine two babies.
Baby A is fairly easy-going. You put her into the cot awake. She rolls around, examines her hands, complains briefly about the injustice of bedtime and eventually falls asleep.
At 2am she wakes, makes a few noises, rolls around and falls asleep again.
Baby B is more emotionally reactive. The moment you put him down, he becomes upset. When he wakes overnight, his distress escalates quickly and he calls for you.
It would be very easy to observe these babies and conclude:
Baby A sleeps well because her parents taught her to fall asleep independently.
But there's another possibility.
Baby A's temperament may make both falling asleep independently and returning to sleep independently easier for her.
And research increasingly supports the role of temperament in sleep.
Higher infant negative emotionality has been associated with more night waking, longer periods awake overnight and more persistent sleep difficulties.
A recent study using objective video measures also found that infant temperament, bedtime practices and sleep were intertwined rather than being neatly separable.
In other words, the baby comes into the equation too.
It's probably not nature or nurture
This is where the research becomes less catchy but more realistic.
Older observational work on infant “self-soothing” found evidence that both infant characteristics and parental responses contribute to how babies learn to settle across the first year.
Which makes intuitive sense.
A baby who becomes very distressed when put down will naturally receive more parental settling.
A baby who lies happily in the cot will naturally be given more opportunity to settle independently.
Over time, the baby's temperament influences what the parent does - and what the parent does may also influence what the baby learns.
It's a feedback loop.
Not simply:
Parents who don’t teach self-settling skills cause overnight waking.
This may explain why controlled comforting works brilliantly for one baby and terribly for another
You've probably heard both stories.
One parent says:
“We did controlled comforting for three nights and it completely changed our lives.”
Another says:
“We tried for two weeks. Everyone cried. Sleep got worse. I thought I was doing it wrong.”
It doesn't necessarily mean one parent implemented the method correctly and the other didn't.
Behavioural approaches have good evidence that they can improve infant sleep, and longer-term follow-up studies have not found marked differences in attachment, emotional difficulties or parent-child relationships after commonly studied behavioural interventions.
But averages don't tell us how an individual baby will respond.
A relatively calm baby who grizzles briefly and settles may find a behavioural approach quite manageable.
A highly reactive baby who goes from slightly unhappy to absolutely beside themselves in approximately eight seconds may have a very different experience.
Temperament is one reason a sleep strategy shouldn't automatically be treated as universally appropriate.
And needing help to fall asleep isn't automatically a sleep problem
This is another leap we make surprisingly often.
Your baby feeds to sleep.
They wake twice overnight.
You feed them for ten minutes.
Everyone goes back to sleep.
Does this require fixing?
Probably not.
If feeding, rocking or cuddling is getting your baby back to sleep quickly and the arrangement is manageable for your family, the fact that your baby isn't falling asleep “independently” doesn't automatically make it a problem.
Sometimes we spend an extraordinary amount of effort trying to remove a sleep association that was actually the fastest route back to sleep.
Sometimes earlier intervention makes more sense
A responsive approach to sleep asks a slightly different question to behavioural approaches.
Instead of:
How long should I wait before helping?
A responsive approach asks:
What does this particular baby need to get back to sleep with the least disruption?
For a baby who wakes briefly and happily rolls around, the answer might be: absolutely nothing.
Leave them to it.
But if you know your baby and know that a little grizzle usually becomes full-blown distress very quickly, intervening earlier may make more sense.
Keep the room dark.
Keep interaction boring.
Feed if feeding works.
Cuddle, pat, rock, replace the dummy - whatever safely gets them settled again.
The aim is to keep them as ‘dialled down’ as possible so that a brief night wake doesn't become a 90-minute party nobody wanted an invitation to.
The goal doesn't have to be “independent sleep”
Perhaps the better goal is:
How do we get the most sleep with the least stress?
For one family, that might involve gradually teaching their baby another way of settling.
For another, it might mean feeding back to sleep because it takes seven minutes and everyone is asleep again by 2.14am.
For another, it might mean sharing night wakes between parents.
And for another, where frequent waking genuinely is becoming unsustainable, a more structured behavioural approach might feel right.
There doesn't have to be one correct answer.
Your baby's sleep isn’t a test of your parenting
If you have a baby who happily falls asleep independently, awesome.
If you have one who would like to lodge a formal complaint every time you move towards the cot, you haven't necessarily missed some critical opportunity to teach them a skill.
Babies arrive with different temperaments, different levels of sensitivity and different capacities for regulation. Their sleep develops within the relationship between biology, development, temperament, environment and the way we respond to them.
Independent settling can be useful.
It can be learned or encouraged to some degree.
And behavioural sleep strategies can absolutely work.
But the research doesn't justify reducing infant sleep to:
Teach your baby to fall asleep alone and they'll sleep through the night.
Sometimes the baby who falls asleep independently and resettles independently simply finds both things easier.
And sometimes the most sensible sleep strategy isn't trying harder to make your baby need you less.
It's working with the baby you've got - and choosing whatever safe, sustainable approach gets everyone back to sleep fastest.
