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.
“I always say bedtime and nap routines can start from day 1. A child is never too young to learn healthy sleep habits and routines! But to get a baby sleeping through the night there are a few things I check. The baby should be at least 15 lbs, no medical concerns, and on a healthy growth curve approved by their pediatrician. If all these points are met, then I'm ready to start getting that little one sleeping through the night!"
Prepare yourself for a few difficult nights. Hearing your baby cry can be excruciating, as every parent knows. During the waiting periods, set a timer and go to a different part of the house, or turn on some music, so you don't have to hear every whimper. As one BabyCenter parent says, "The first week could be rough. Try to relax and know that when it's all over, everyone in your household is going to sleep more easily and happily."
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.
