McKenna advises against sleep training and encouraging babies to sleep for long stretches at night. Instead, he urges parents to follow their babies' cues and allow them to wake frequently through the night to feed. A strong advocate for co-sleeping, McKenna encourages bed-sharing and other co-sleeping arrangements, such as putting the baby in a bassinet or crib at the parent's bedside, while also following standard SIDS safety precautions – for example, making sure there are no blankets or stuffed animals around him.
"I tried Tracy Hogg's approach: Don't leave the baby to cry! Instead, when he starts up, go in there, pick him up, and love him until he stops. Once he's calm, lay him back down. If he starts crying again, repeat. Eventually he'll know it's time to sleep. Hogg said she had to do it 126 times with one child, but it dropped to 30 the next night, four the next, and soon she didn't have to do it at all. I tried this with my 3-month-old and it worked like a charm!"
With the fading technique, continue with whatever method you were using to help your baby fall asleep (such as rocking or nursing), but decrease the amount of time you spend doing it until, in theory, you don’t have to do it at all. This is a great technique for minimizing crying, but unfortunately, many parents find it difficult to sustain. “There has to be an end in sight,” explains Mitelman. “For example, we’ll meet this need for five to seven days and then we’ll pull back a little bit.” But if you’re willing to stick to the plan and get your baby to the end goal of going to bed without your assistance, Mitelman says it’s worth a try. “Whichever way the child can get to sleep independently is fine because that’s the key ingredient to sleeping through the night.”
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.
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.
