It might be strange to think of sleeping as a skill that does not come naturally. As a new parent, you’re probably so exhausted that you pass out as soon as your head hits the pillow. Your baby, however, doesn’t have this same ability yet. Although they spend a lot of time sleeping, they need to learn when to sleep (day vs. night) and how to sleep. Until they do, they need your assistance, which is why you (as you should) help soothe them to sleep at bedtime and comfort them when they wake in the middle of the night. Sleep training is teaching your baby how to sleep without any help from you - just like you’re able to fall asleep without anyone there to help you do it.
Proponents of these sleep training methods say it's okay for your child to cry when you put him to bed and leave the room, although they don't advocate letting a baby cry indefinitely. Typically, these methods suggest putting your baby to bed when he's still awake and allowing short periods of crying punctuated by comforting (but not picking up) your child.
"My son is 6 months old and finally goes to sleep without a struggle! We thought the Ferber method was mean and that alternatives would be better. So we tried it all – Baby Whisperer, No-Cry Sleep Solution, Babywise, etc. None of it worked. Our son is an otherwise happy little guy, but every night and every nap was a battle. We'd spend hours trying to get him to sleep. We delayed trying Ferber until we'd tried everything else unsuccessfully. It worked after the first night! He wakes up better rested and happier (as do we)."
There is no right or wrong method of sleep training; it all comes down to your unique baby and your unique parenting style. What works well for some babies does not work well for others, so do not be surprised if the techniques your friends or family members recommend don’t work the same way for your baby. The bottom line is to choose a technique that you feel comfortable with, and that you think will work well with your baby’s temperament.
"As a last resort, I broke down and gave Ferber a try. It's been two and a half weeks, and I see no real improvement. My daughter goes down faster at night, but the crying breaks my heart. I miss snuggling with her. She still wakes up every 30 to 90 minutes after her first two-hour stretch. She shrieks when it's time for a nap. I broke down and nursed her to sleep for her afternoon nap because I couldn't stand to see her so exhausted."
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.
