On the advice of a sleep consultant, Welk and her husband took away Greyson’s pacifier, moved his bottle to before his bath (so he wouldn’t associate feeding with going to sleep) and chose to start with a very gentle method (because he was only four months old at the time). Greyson’s dad put him in the crib and stood next to him, patting him until he fell asleep, for about a week. That went well, and then they started leaving him immediately after putting him in the crib without patting him fully to sleep. “For about a month, he would cry or fuss every night for 10 to 15 minutes before falling asleep,” recalls Welk. It was hard to hear her baby cry, but she feels confident that it was for the greater good because they were both well rested and happy during the day. Now, Greyson is 11 months old and a champ sleeper, having weaned himself from night feeds at seven months.
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.
C.I.O. is the most famous sleep training technique, and the most controversial — although, despite its daunting name, it is safe and effective. In its simplest form, unmodified extinction, you place your infant down at bedtime, drowsy but awake, and then leave the room, without returning to check on or soothe your baby. This method will work quickly, but often produces prolonged periods of crying for a few nights, which can be difficult for parents to tolerate.
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.
