Some experts suggest techniques that are slightly different than these methods. Perhaps the best known is pediatrician Harvey Karp, author of The Happiest Baby on the Block. His method suggests a very specific routine involving the so-called five S's: swaddling, the side or stomach position (for calming your baby, not for sleeping), shushing, swinging, and sucking.
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.
This is another gentler technique. The PUPD method works just the way it sounds: when it’s time to sleep, and your baby is fussing or crying in his crib or bassinet, you pick him up and comfort him until he’s calm and drowsy. Then, you put him back in his crib to sleep, repeating this cycle until your baby is finally asleep. PUPD is another method that requires quite a bit of patience, depending on your baby, and it won’t work for every baby; some babies find being picked up and put down so often over-stimulating, and they gradually become frustrated and worked up, instead of relaxed.
• DIY methods work. Don’t love the rigidity of a particular method? Modify it to suit your own family’s circumstances. Sometimes, a sleep coach can be helpful to come up with modifications that won’t affect the goal of getting baby to sleep through the night, but it’s fine to mix and match until you find a strategy you’re comfortable with. “I don’t think I’ve ever loved and loathed anything as much as I do sleep training. We did it with my son because he was still waking up every three hours at 3.5 months old, and I felt it was more out of habit,” says Margaret, a mom of one. “My husband and I decided that we valued teaching him self-soothing and that in the long run it was worth some short-term effort. I did a ton of research and came up with our own plan—similar to Ferber, but our time limits of letting him fuss weren’t as rigid. It worked, and he’s been a solid sleeper since.”
