Once you launch your plan, stick to it. Parents who've been through sleep training agree that consistency is the key. Unless you realize that your child simply isn't physically or emotionally ready and you decide to put the program on hold for a while, follow through with it for a couple of weeks. When your baby wakes you up at 2 a.m., you may be tempted to give in and hold or rock him, but if you do, your hard work will be wasted and you'll have to start over from square one.
The idea behind extinction (or full extinction to differentiate it from graduated extinction) is that you want to extinguish the behaviour (crying) by not responding to it. As with the check-and-console method, go through your bedtime routine, put them in their crib awake, say good night and walk out. This is certainly the most controversial sleep-training method, and even experts disagree on what you should do next—it all depends on what stage your baby is at developmentally, as well as what works for the parents.
All sleep-training methods have pros and cons, says Vanessa Vance, a child-sleep consultant in Austin, Texas, so it’s important to suss out which one is best for you. “When I work with a family, we discuss what their needs and goals are. Some families may not want any crying, so a gradual approach may work best,” she says. Here, an overview of some of the most popular sleep-training methods:
• Pick-up-put-down method. In this sleep-training method, you put your child to bed while he’s awake and check on him at gradual intervals, as you do with the Ferber method. Unlike with Ferber, you can pick him up and comfort him, holding him for a few minutes before putting him down. Eventually baby will become drowsy enough to fall asleep on his own.
As your baby gets older and their sleep needs change, make sure that you’re adjusting wake times, naps and bedtimes accordingly to help them continue to easily fall asleep 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.
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. At this stage, most babies are also 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.
