Exhausted new parents and certified sleep consultants swear by some of these sleep-training techniques. Here’s what you need to know before you get started.

For the first few months of his life, Laura Welk’s baby, Greyson, was a dream sleeper. He had regular naps during the day, and all it took was a calming bottle in the evenings, and he would be fast asleep. He would wake up only once a night for a feed, and that would last him until morning.
But when he was about three-and-a-half months old, the routine fell apart. “I would feed him, but he wouldn’t be asleep at the end of the feed,” recalls Welk. “I would rock him until he fell asleep and put him down, and then he would wake up 30 minutes later, and I would repeat the process all over again.”
Welk was desperate for rest, so she brought Greyson into bed. However, she ended up lying still all night, holding a pacifier in his mouth.“I didn’t know anything about sleep,” says Welk. “I didn’t know you couldn’t just rock them to sleep and then put them down.”
When Greyson was four months old, the new parents consulted a sleep consultant. The consultant explained that Greyson's frequent rocking and pacifier use had become ingrained sleep associations, meaning he relied on these "crutches" to fall and stay asleep. They decided to sleep-train him.
Sleep training is a loaded phrase. It's often used synonymously with letting your baby self-soothe, or “cry it out,” but that’s not the whole picture, says Alanna McGinn, a certified sleep consultant and the founder of Good Night Sleep Site. “It’s more about being able to teach your baby that they are capable of falling asleep independently,” she says.
You want your baby to be able to nod off on their own—ideally without nursing, rocking or using a pacifier—because whatever tools they use to fall asleep at bedtime are the same things they’re going to wake up looking for during the night. Yes, this can feel unloving and even downright cruel.
Experts hold differing views on this topic. Breastfeeding advocates state that it's normal for babies of all ages to wake frequently to nurse. Even the sleep coaches interviewed for this article disagree on the acceptable amount of crying and distress.
There are many variations on the check-and-console method, but the general principles are the same: You want to continue to check on your baby at preset intervals but never feed or rock them to sleep, as that would mean they aren’t falling asleep on their own.
This technique could take up to a week to work, but you should start seeing some progress after a few nights. Many experts recommend keeping a sleep-training log to help reassure yourself. Some parents find that going into the room aggravates the baby even more and might consider a more direct method, like full extinction.
The idea behind extinction, also called full extinction to distinguish it from graduated extinction, is to stop the crying behaviour by not responding to it. As with the check-and-console method, go through your bedtime routine, put them in their crib awake, say goodnight and walk out.
This is certainly the most controversial sleep-training method, and even experts disagree on what to do next—it all depends on what stage your baby is at developmentally and what works for the parents.
Parents are often hesitant to go this route, worried about how much crying will be involved. While McGinn doesn’t deny it can be difficult at first, she finds parents are often surprised by how quickly it works. “Yes, there is a lot of crying, but it’s short-term,” she says. “You might get a lot of crying for two to three nights, but then every night is less and less.”
She says you should see significant improvement with this method by night three or four, but adds that it’s important to try it for a week before determining that it’s not working.
This is a very gradual sleep-training method (McGinn gives her clients a two-week plan for implementation) and requires a lot of discipline on the part of the parents. Again, you prep your baby for bed, but instead of leaving the room, you sit in a chair next to the crib.
“The pro of this method is that mom or dad is there and present,” says McGinn. “But the con is, there will likely still be some crying, and now baby is watching you watch them cry. It can be really hard to be consistent with this method.”
Mitelman doesn’t recommend this method to her clients because she says having a parent in the room but not responding to the baby is confusing and may also be too much stimulation, depending on the baby’s age and developmental stage.
“They can get so escalated to the point that they can’t calm themselves down,” she says.
For babies younger than seven months, Garden prefers an approach where you stay in the room without giving them too much help to fall asleep.
While these methods can work really well for younger babies, after six or seven months, your presence might make your baby more upset, and picking them up and putting them back down will likely be too much stimulation.
With the fading technique, continue with whatever method you were using to help your baby fall asleep (such as rocking or nursing), but decrease the amount of time you spend doing it until, in theory, you don’t have to do it at all. This is a great technique for minimizing crying, but unfortunately, many parents find it difficult to sustain.
“There has to be an end in sight,” explains Mitelman. “For example, we’ll meet this need for five to seven days, and then we’ll pull back a little bit.” But if you’re willing to stick to the plan and get your baby to the end goal of going to bed without your assistance, Mitelman says it’s worth a try.
“Whichever way the child can get to sleep independently is fine because that’s the key ingredient to sleeping through the night.”
Not to be confused with the bedtime-routine fading technique described above, bedtime-hour fading involves putting your baby into the crib at the time they usually end up dozing off, and making that their new bedtime for a couple of nights, and then gradually moving it to an earlier time.
While McGinn doesn’t use this technique with her clients, she says the trick with any training routine is to be very consistent and commit to moving the bedtime routine earlier. “It’s easy to become inconsistent with things or give up, and then the child has a really late bedtime,” says McGinn
Recent research has shown that, at least in babies older than six months, sleep training with controlled crying and bedtime fading (both described below) improved babies’ sleep and didn’t lead to increased cortisol levels. This provides some reassurance that a little bit of crying, if it leads to better sleep, likely won’t do your baby any harm.
Pediatrician Michael Dickinson, president of the Canadian Paediatric Society, advises parents to trust their instincts. “I don’t think there’s any evidence to suggest that it’s psychologically damaging to let your baby cry, but I think people need to be reasonable,” he says. “For most of us, letting your baby cry is five to 10 minutes.”
There’s also no need to institute a regimented cry-it-out plan if what you’re currently doing is working for your family. But good sleep habits never hurt, and being able to fall asleep on one's own is a necessary life skill. If you sleep-train at a developmentally appropriate time for your baby and with the basic ingredients of healthy sleep in place, you can minimize the amount of crying your baby (and, let’s face it, you) will do.
Most sleep coaches say the ideal time to start sleep training (or promote independent sleep, not necessarily using the cry-it-out method) is based on your baby’s development, but is usually somewhere between four and six months, when your baby hasn’t had much time to get used to nursing or rocking to sleep.
During this stage, most babies are developmentally ready to learn the skill of falling asleep on their own, explains Jennifer Garden, an occupational therapist who runs Sleepdreams in Vancouver.
Around four months of age, some babies go through a sleep regression because their sleep cycles change, and there are longer periods of lighter sleep per cycle. “It’s a great time to work on independent sleep skills,” says McGinn. Other babies’ slumber derails around this time because they are working on new skills, like moving around and rolling.
Some parents choose to wait until things settle down before embarking on a sleep-training method, but you don’t have to, says McGinn.
If your baby is older than six months, don’t worry, McGinn says: “It’s never too late to develop good sleep habits.” Dickinson says he finds nine months to be a bit of a sweet spot for parents in terms of getting babies to sleep through the night. “They are at a good age for understanding routines and don’t need to eat during the night,” he explains.
The age of your baby might determine what kind of sleep-training method you choose, though. You could try a gentle shush-pat technique with a five-month-old, but you’ll likely have to leave a one-year-old in the crib as they protest (cry or scream) about the new bedtime arrangement.
Don’t attempt a formal sleep-training method before four months, until your baby can go longer in between feeds and their circadian rhythm starts to develop. (Many babies this age still feed in the night—contrary to popular thinking, sleep training isn’t synonymous with night weaning.)
Dickinson says that many four-month-old babies are biologically able to go through the night without a feed, but that doesn’t mean you shouldn’t respond and feed them if other methods of calming them aren’t working. Since every situation is different, we recommend checking with your doctor before withholding your baby’s nighttime feeds.
Before you even think about “training” your baby to fall asleep on their own, make sure you’re following a regular schedule and putting them to bed at a consistent time each night (hint: early is usually better, typically around 7 or 8 p.m.). Starting at about two months old, it’s a good idea to try to put them down drowsy but awake whenever you can, just to get them (and you) used to it, even if they fuss a bit.
Make sure that they’ve been awake for an appropriate amount of time before bed (an over- or under-tired baby will have trouble falling asleep), and establish a calming and consistent bedtime routine, like a feed, bath or massage followed by pajamas and stories or songs.
Some experts recommend feeding at the beginning of the routine to avoid having the baby associate the feeding with falling asleep. Ideally, your baby won’t have started to nod off at any point during your bedtime routine.
“You really want to make sure your baby is primed for sleep,” says Pamela Mitelman, a psychologist in Montreal who specializes in infant and child sleep. Be conscious, too, of filling their daytime awake periods with enough activity and stimulation, says Garden.
“Kids need to be moving in all sorts of ways when they are awake, not just sitting in a bouncy chair,” she says.
Once you’ve got all the ingredients of a good night’s sleep in place and you’re ready to let your baby learn how to fall asleep on their own, here are six common methods to consider.
On the advice of a sleep consultant, Welk and her husband took away Greyson’s pacifier, moved his bottle to before his bath (so he wouldn’t associate feeding with going to sleep) and chose to start with a very gentle method (because he was only four months old at the time). Greyson’s dad put him in the crib and stood next to him, patting him until he fell asleep, for about a week.
That went well, and then they started leaving him immediately after putting him in the crib without patting him fully to sleep. “For about a month, he would cry or fuss every night for 10 to 15 minutes before falling asleep,” recalls Welk.
It was hard to hear her baby cry, but she feels confident it was for the greater good because they were both well-rested and happy during the day. Now, Greyson is 11 months old and a champ sleeper, having weaned himself from night feeds at seven months.
If you’re on the fence about sleep training, it can be helpful to think of it this way: What is my baby’s developmental need right now? “At 11 months, they don’t need to eat during the night, but they do need consistent sleep,” says Garden. Yes, those nights of crying are heartbreaking. But chances are, if you’re considering sleep training, it’s because what you’re currently doing isn’t working for you.
As your baby gets older and their sleep needs change, adjust wake times, naps and bedtimes accordingly to help them continue to fall asleep easily and stay asleep. Some parents think of sleep training as a “one-and-done” endeavour: You endure a lot of crying for a few days, and your prize is a perfect sleeper.
But it’s really a lifestyle change—once your child has the skills to fall asleep, they’ll still need routines, consistency and help adapting when life throws curveballs, like starting daycare, the arrival of a new sibling or going on a trip (where they may have to sleep in a different space or crib).
Colds and illnesses, as well as time changes, can also throw a wrench in your perfect schedule. The trick here is to get back on track as soon as possible. If you start allowing or enabling the old, bad habits and sleep associations, it will take longer to return to the regular routine.
McGinn likens it to riding a bike: Sure, kids are a little wobbly when you get the bike out after the winter, but soon they’re riding like pros again. “You never have to re-teach the skill of falling asleep,” she says.
Do your research, talk to your doctor, and if you're overwhelmed, consider hiring a sleep consultant or taking a workshop. Your baby’s sleep might seem like a mystery to you, but some people understand the complexities and can help. While not everyone agrees with every approach, no one would argue with the benefits of a good night’s sleep for babies and exhausted parents alike.
