This is a very gradual sleep-training method ( McGinn gives her clients a two-week plan for implementation) and requires a lot of discipline on the part of the parents. Again, you prep your baby for bed, but instead of leaving the room, you sit in a chair next to the crib. When they fall asleep, leave the room, but every time they wake up, sit back down in the chair until they fall back asleep. Every few nights, move the chair further and further away until you’re out of the room.
"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!"
This is considered a ‘cry’ method of sleep training. This technique entails allowing your baby to cry while checking on him at intervals. The goal here is to reassure him every so often that you are nearby and to reassure yourself that he is okay. When you go to check on your baby, you are not “supposed” to pick him up nor engage him much, but simply reassure him using your voice and a loving pat for 2-3 minutes, tops (watch the clock!). With this sleep training method, the goal is NOT to help baby fall asleep – that is what he is learning to do on his own! Instead, the idea is that he falls asleep on his own, in the same “environment” in which he will awaken periodically throughout the night. The knowledge of how to fall asleep unassisted at bedtime will pave the way for him/her to go BACK to sleep throughout the night. Over time, you gradually increase the amount of time between your ‘checks’. See a more detailed step-by-step explanation of this method here: The Ferber Method
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 4-and-a-half-month-old will only sleep through the night if we do everything the experts say not to do. She must be nursed to sleep unless we want to see her turn purple and cry for 45 minutes or more. She's like a wind-up doll when she starts and never settles until she's comforted, and she's been that way from the beginning. It really became a matter of, "Do we want to sleep, or do we want to do what the books say?" If she's comforted and put down sleeping, she sleeps eight to 10 hours. To all you parents out there who have a baby like mine, do not despair – just do what works for you."
A version of this technique called graduated extinction was popularized by Dr. Richard Ferber in his book “Solve Your Child’s Sleep Problems.” Here, parents check on their child at set intervals. Checks should be brief and to the point: Picking up your child, spending too much time hovering over the crib or otherwise offering more contact than a quick soothing word can be counterproductive. Some babies find these brief checks soothing and will go to sleep more quickly. Others will redouble their crying as soon as their parents leave the room. Parents need to make a judgement about whether or not checking in is helping their baby through this process. If you decide to use checks, I would recommend checking no more than every five minutes and resisting the temptation to check if your child seems to be calming down.
A consistent bedtime routine is the cornerstone of good sleep for children. It should also be a time for parents and babies to bond. Bedtime routines need not be complex. Bathe your child (if you like), change her into pajamas, read her a story, sing a song and feed or soothe her, then put her in her crib. The key is consistency — performing the same activities, in the same sequence, at the same time each evening.
If your baby is older than six months, don’t worry, McGinn says: “It’s never too late to develop good sleep habits.” Dickinson says he finds nine months to be a bit of a sweet spot for parents in terms of getting babies to sleep through the night. “They are at a good age for understanding routines and don’t need to eat during the night,” he explains.
