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.
Sears emphasizes a nurturing, child-centered approach to sleep and warns parents to be wary of one-size-fits-all sleep training. He recommends patiently helping your baby learn to sleep in his own time. He encourages co-sleeping, rocking and nursing your baby to sleep, and other forms of physical closeness to create positive sleep associations now and healthy sleep habits down the road.
"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)."
• 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.
"I have a 5 1/2-month-old baby girl who has never once in her life "cried it out." From night one in the hospital, she has slept with me. She is rocked and nursed to sleep and when she starts to grunt/wiggle beside me, I simply shift near enough for her to latch on to my breast, and she nurses back to a deep sleep before either of us fully wakes. I follow Dr. Sears' attachment style parenting and my baby has never once in all her life cried during the night or even fully woken up."
• No tears method. Created by sleep expert Elizabeth Pantley, this technique, also known as the no-cry method, involves subtly shifting your child’s sleep habits. For example, one trick, known as “fading,” suggests gradually easing out of baby’s go-to sleep strategy. For instance, if she always needs to be rocked, you would rock less and less until you can put her down to sleep without any rocking. Another technique, called substitution, switches out the routine—so if baby always nurses before bedtime, read a book instead.
