Unlocking the Mystery: When Can Newborns Start Sleeping Through the Night? Expert Insights and Tips
Congratulations on welcoming your precious little one!
The early days with a newborn are magical, yet they can be overwhelming as you navigate the ins and outs of caring for your tiny human.
In these crucial first 12 weeks, focus on mastering two key elements: feeding and sleeping. These are intertwined, and success in both can make you the champion of life and the envy of your coffee group.
During the initial weeks, your newborn relies on you to guide them to sleep. This might feel like a full-time job, as newborns are still too young neurologically to self-soothe. Whether through holding, rocking, patting, or allowing them to suck, your comforting touch is essential when they're upset.
While it's true that your baby will sleep a lot in the first weeks, these snoozes will be brief and frequent, necessitated by their tiny tummies needing regular filling. The intermittent sleep pattern can be challenging, especially during the night when waking to feed and resettling interrupts your own rest.
Many parents consider turning to formula feeding, hoping it will lead to better sleep for their babies at night. But what does the science say? Is swapping breastfeeding for formula feeding the key to achieving consolidated night sleep? Let's explore the facts.
Study shows breastfed babies as young as 8 weeks can sleep through the night
Teresa Pinilla and Leann L. Birch from the University of Illinois set out to investigate whether exclusively breast-fed infants could be taught to sleep through the night (defined as a 5 hour stretch of sleep… I know, probably not as long as you imagined when I said sleep through the night, but this stat was defined in the 70’s and hasn’t changed) during the first 8 weeks of life.
Twenty six first-time parents were randomly assigned to a treatment or control group.
Those parents in the treatment group offered their infants a ‘dream feed’ every night between 10pm and 12am and were instructed to gradually lengthen the intervals between this dream feed and the next middle-of-the-night feed by using alternative caretaking behaviors like re-swaddling, walking, changing the nappy…..
The treatment group was also instructed to take steps to maximise environmental differences between day and night-time.
Day time feeds are bright and light, there is chatting from parents, there is play time after feeds, and mum is animated and fun!
Night-time feeds are done under dim lights, little to no interaction, and no play time, just a quick nappy change, settle and back to bed. These environmental differences combined with using alternative caretaking behaviours to lengthen the time between feeds worked!
The researchers found that by just three weeks old, infants in the treatment group showed significantly longer sleep episodes at night….3 weeks!
Now every bit of online literature you read including my own sleep guides will say, you can’t sleep train a new-born.
But this isn’t sleep training, this is very basic steps taken in a nurturing environment to help encourage longer night sleep, and it works!
By the time they were 8 weeks old 100% of those infants were sleeping through the night (as per the definition above – just 5 hours…but if you’re a new mum 5 hours probably sounds like bliss right now) compared to only 23% of infants in the control group.
The babies in the treatment group were feeding less frequently at night but compensated for this by consuming more milk in the early morning so that overall milk intake did not differ between the two groups.
These exclusively breastfed babies totally regulated their calorie intake!
No formula needed.
If you’re a breastfeeding mum struggling with the idea of giving a formula top up at night for better sleep, know that even exclusively breastfed your babies can sleep well at night.
Teresa Pinilla and Leann L. Birch from the University of Illinois pointed out that frequent night waking in breastfed infants often resulted in early termination of breastfeeding.
This research confirmed that parents can teach their breast-fed infants to lengthen their night-time sleep, meaning more sleep for everyone, and hopefully helping parents who want to exclusively breastfeed continue to do so without sacrificing sleep.
What to expect – week by week
Studies like this back up what we at Baby Sleep Consultant live by - that parents can have a powerful influence on the development of their baby’s sleep. Sleep is malleable.
Sometimes, it’s hard to know what we should aim for, or what realistic expectations could be, but if you’re a tired parent struggling to get enough sleep, you can take comfort in knowing that it is scientifically possible for your little one to get a solid stretch of night-time sleep even in those first few months.
Jodi A. Mindell published another study in Pediatrics in 2016.
Dr Mindell explains that inadequate sleep during infant years is associated with adverse outcomes for babies and families, and she wanted to test a hypothesis that she could improve sleep behaviours through a responsive parenting intervention education delivered to new parents.
What was the education these new parents received?
Parents were taught about different baby behavioural states, drowsy, sleepy, fussy and alert. More importantly they were taught ways to soothe a fussy baby without feeding a non hungry baby.
The parents enrolled in Dr Mindells study were taught developmentally appropriate bed time routines, sleep locations, and behaviours.
Realistic night waking’s were explained, and parents began to understand how to recognise whether their baby was fussy due to fatigue or hunger.
As the weeks went by, parents were shown information on routines before bed to avoid feeding to sleep, the importance of self-soothing to sleep and after night waking’s. Early bed times, and working towards self-soothing was encouraged by the nurses delivering the sleep education.
Teach new parents all of this and more.... Ensuring you have realistic ideas about sleep, and know exactly what to do to naturally move the dial when it comes to more night sleep, better quality sleep, easier settling, and confidence as a mum.
The results of this study are impressive and back up what we are teaching here at Baby Sleep Consultant.
By 16 weeks the babies involved in the study had shorter bed time routines, settled easier, and had earlier bed times. 44% of these babies were self soothing by 16 weeks with no formal sleep training, and just like the babies in the first study, their total night sleep was longer than the control group who didn’t receive the sleep education.
Better sleep is possible, but it’s not going to happen from day one. So, what is most important – and realistic – in your baby’s first year?
The complete list of what Dr Mindells study recipients received is below…. The good news? This is ALL covered in our online sleep programs!
- Bedtime routine
- Consistent routine beginning 30–45 min before bedtime
- Choose age-appropriate, calm bedtime activity
- Feeding not the last step before bed
- Cereal in the bottle does not improve sleep
- Sleep location and behaviours
- Age-appropriate sleep duration guidance
- Best bedtime is 7–8 pm
- Avoid stimulating environment at bedtime (low light, no TV, etc)
- Use white noise
- Use swaddle blanket
- Pacifier use
- Transition to own room by 3 months
- Consistently put to bed drowsy but still awake by 4 months
- Avoid rocking, feeding to sleep
- Allow infant some time to self-soothe when put down for night
- Nap frequency, duration, and routines
- Strategies for separation anxiety affecting sleep
- Night waking
- Respond differently night vs day
- Stop waking infant routinely to feed at night
- Caretaking behaviours other than feeding: 5 S’s
- Feed before parent’s bedtime: “dream feed”
- Avoid starting “dream feeds” after age 4 months
- Allow infant some time to self-soothe when waking at night
- Possible increased frequency around developmental advances (leaps regressions)
- Do not reinforce waking; keep night interactions with child boring
- Avoid overnight feeds; infants can sleep 8–12 h without eating (3-6 months)
- Personalized sleep profile (sleep temperament)
Sleep is not easy.
You’ll have good days and bad days but there are gentle and proven solutions backed by science that we know work.
