"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."
That said, sleep training isn’t a must-do for everyone, and many families who skip sleep training go on to have a child who learns to sleep through the night on her own. “It’s your family and your child, and I think there’s a misconception that pediatricians will force sleep training on your family, when that’s not the case,” Gold says. Experts emphasize that the best approach to sleep training is the one that fits your family.
“There are many variations to any sleep training method. For example, you can do a cross between The Chair Method and PUPD with great success and fewer tears! There are also ways of breaking each method into smaller baby steps, which we recommend very often in our Personalized Sleep Plans®. Find what feels tolerable (because, frankly, no one ‘likes’ to sleep train), more comfortable for you, and what seems the gentlest, yet effective, on your baby, depending on his or her temperament and personality.”
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.
"My 3-month-old doesn't sleep through the night, and it's fine with me. I keep her in her crib or a bassinet until her 3 a.m. feeding, and then she joins my husband and me until we get up for work. She won't go in her crib unless she's already asleep, usually from nursing and rocking, but she'll fall asleep in her bassinet beside our bed. She's happy and we're happy, and even if it goes against the wisdom of the experts, it's working for us."
Some experts suggest techniques that are slightly different than these methods. Perhaps the best known is pediatrician Harvey Karp, author of The Happiest Baby on the Block. His method suggests a very specific routine involving the so-called five S's: swaddling, the side or stomach position (for calming your baby, not for sleeping), shushing, swinging, and sucking.
• Know there will be regressions. Teething, illness, vacation and routine shifts all can lead to poor sleep, and that’s all right, Vance says. “Often, you may have to go back to training for a day or two to get back on track, but you won’t lose ground. If your child has been trained to be a good sleeper, one week off schedule because of vacation won’t change that.”
Sleep training is a loaded phrase, and one that is often used synonymously with letting your baby self-soothe, or “cry it out,” but that’s not the whole picture, says Alanna McGinn, a certified sleep consultant and the founder of Good Night Sleep Site. “It’s more about being able to teach your baby that they are capable of falling asleep independently,” she says. You want your baby to be able to nod off on their own—ideally without nursing, rocking or using a pacifier—because whatever tools they use to fall asleep at bedtime are the same things they’re going to wake up looking for during the night. Yes, this can feel unloving and even downright cruel. You’ll find experts on both sides of the issue: Breastfeeding advocates say it’s normal for babies of all ages to wake up multiple times to nurse, and even the sleep coaches interviewed for this article disagree with how much crying and distress are acceptable.
