• Chair method. Also called the sleep lady shuffle or gradual withdrawal and popularized by Kim West, LCSW-C, author of Good Night, Sleep Tight, this method starts with you sitting in a chair next to baby’s crib. Each night, you move the chair farther away from the crib, verbally soothing or shushing baby when she cries (although occasional patting and picking up are okay) until you’re no longer in the room. This method can be helpful for older babies and toddlers who may suffer from separation anxiety and can understand that Mom and Dad are just on the other side of the door, but it also works for younger babies.
Exhausted parents may be eager to get training underway—so how do you know when to start sleep training? “Most infants are ready for some sort of sleep training at 4 to 6 months,” says Lauren Kupersmith, MD, a clinical instructor at the department of pediatrics at NYU Langone Medical Center. “While some pediatricians adhere to the guidelines that infants are ready to be sleep trained when they achieve a particular weight, I feel it’s much more appropriate to wait until they are developmentally ready to self-soothe, at about 4 months old.”
Sleep experts who support the cry it out approach (as well as most pediatricians) disagree. They say it isn't traumatic for babies to cry alone for short periods of time with frequent check-ins by Mom or Dad – and the end result is a well-rested, happier child. They say no tears sleep strategies may cause babies to be overly dependent on comfort from a parent at bedtime, making it harder for them to learn to soothe themselves to sleep.
One common misconception about sleep training babies (also called sleep coaching) is that there’s only one way to do it. But this could not be further from the truth! In reality, there are a number of ways many parents can work to help their babies develop healthy sleep habits and stop waking up in the middle of the night or taking short naps. Some methods involve crying, but others involve little to no tears and are very gentle.
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.
