Most experts recommend starting when your baby is between 4 and 6 months old. By about 4 months, babies have typically started to develop a regular sleep-wake cycle and dropped most of their night feedings. These are signs they may be ready to start sleep training. Many babies this age are also developmentally able to sleep for long stretches at night.
"My 5-month-old was waking every two hours at night. I was so tired I wanted to die. I finally caved in, put in earplugs, and let him cry it out – which he did, all night! But then, something amazing happened the next night: He slept a full 12 hours and awoke rosy and cheerful. It's been that way ever since, and he's even a better napper now. I know that it is hard to listen to your precious little one cry, but a sleep-deprived, miserable mom and baby is a terrible thing too."
"A young child cannot yet understand what is best for him, and he may cry if he does not get what he wants," Ferber writes. "If he wanted to play with a sharp knife, you would not give it to him no matter how hard he cried, and you would not feel guilty or worry about psychological consequences. Poor sleep patterns are also harmful for your child and it is your job to correct them."
"I have two kids. The first one was never left to cry it out – we rocked, sung, walked, drove her to sleep until she was old enough to be read a story. Then, with baby number two, I decided to try CIO and after one night, it worked. At 12 months, she goes to sleep at night by herself and never cries. It was the best thing I did. My husband was against it, but he wasn't the one up four or five times every night for nine months straight! Now our household is very happy and everybody sleeps well."
One of the biggest mistakes parents make, no matter what method they use, is being inconsistent. At some point your little one will cry for you in the middle of the night, even if you think you've all made it over the sleep-training hump. Go to his cribside to check on him and make sure all is well—just be sure not to restart an old sleep crutch during this check. After that, try comforting him from outside the door, if you can. If you regress due to illness or travel, get back on the training wagon as soon as possible. Otherwise you risk sabotaging the weeks of hard work you've already put in.
"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."
If you have a hard time remembering how many times your baby woke last night, much less how she slept last week, a log will help you notice patterns. After a week of tracking her days and nights, start by figuring out her ideal bedtime. You might say, "Oh, she's always fussy at 7 p.m.—that's probably when I should be putting her down, and I'm missing the window." A log will also let you see that your baby may not have cried during the night for as long as you thought. Five minutes of fussing can feel like 50 when it's 2 a.m.
There’s an awful lot of information on how to sleep train out there, leaving most parents confused, frustrated, and still wondering what sleep training is and how to do it. In this article, we’ve rounded up all the facts from real moms and professional sleep consultants on what sleep training is, how to do it, and how to decide if it’s right for you.
If you’re on the fence about sleep training, it can be helpful to think of it this way: What is my baby’s developmental need right now? “At 11 months, they don’t need to eat during the night but they do need consistent sleep,” says Garden. Yes, those nights of crying are heartbreaking. But chances are, if you’re considering sleep training, it’s because what you’re currently doing isn’t working for you.
There are many different sleep training methods to choose from, but the most common methods are one of or a variation of one the five we've explained below. You might find that one of these methods sounds like it would be a perfect match for you, OR you might find aspects from each plan that you like. Just like Melissa said, don't feel like you need to stick to a certain method 100%. Make the plan work for you!
West says once an infant is older than 3 or 4 months, habits like rocking, singing, or nursing her until she dozes off become "sleep crutches." "These are not negative or bad behaviors," says West, "but they become a problem when they're so closely linked in the child's mind with slumber that he cannot drift off without them." Continuing with these sleep crutches will mean every time your baby wakes up (multiple times throughout the night), she'll need you to rock, sing, or nurse her—but your goal is to teach her to self-soothe and put herself back to sleep.
My baby just turned 10 months and up until now she’s been co-sleeping with me and being nursed back to sleep. However, she’s been waking so frequently neither of us seem to be getting any sleep. I recently started the CIO method, am now on the 3rd night and it’s very stressful as she cries for almost an hour before falling asleep. I tried this wake and sleep method before, but every time I’d lay her down she’d start crying. Is she maybe too old for this method or too dependent on being held while she sleeps? I’m not sure of what to do at this point but I NEED her to learn how to self soothe before I hit rock bottom.
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.
The benefits of sleep training baby can be substantial: Everyone in the household will be well rested, and sleep is essential to baby’s development. A landmark 2007 study from the National Institutes of Health suggested that critical brain-development periods are dependent on adequate sleep. “Sleep training baby may not be fun, but I always tell families that it’s not dangerous, and developing good sleep hygiene is, in my opinion, one of the best things you can do for your child,” Gold says.
Run through your bedtime routine with the lights on, then place your baby in the crib drowsy but awake. Expect some tears, especially if she's used to falling asleep in your arms. For the first three nights, sit next to the crib in a chair, offering gentle, intermittent reassurances and occasional touches. If she becomes hysterical you can pick her up, but put her back as soon as she calms down. Stay beside the crib until she's sound asleep. Respond to night wakings the same way.
"By the time your baby is 3 months old and has developed a fairly predictable 24-hour pattern, it becomes more important for you to provide increasingly consistent structure. If you do your best to establish a reasonable and consistent daily routine and keep to it as much as possible, then it is likely that your child will continue to develop good patterns. If instead you allow the times of your child's feedings, playtimes, baths, and other activities to change constantly, chances are his sleep will become irregular as well."
But when he was about three-and-a-half months old, the routine fell apart. “I would feed him, but he wouldn’t be asleep at the end of the feed,” recalls Welk. “I would rock him until he fell asleep and put him down, and then he would wake up 30 minutes later and I would do it all over again.” Desperate for some rest, Welk brought Greyson into bed with her, but then she ended up just lying still, holding a pacifier in his mouth all night long. “I didn’t know anything about sleep,” says Welk. “I didn’t know you couldn’t just rock them to sleep and then put them down.”
