For my wife and me, those early days passed in a blur. Nights seemed endless, and no government ordinance was about to come along to shorten our shifts. When he was around 3 months old, our son started sleeping for longer periods and our relief was profound. But after about a month, the baby started waking up at night again. After one nightly waking became two, then three and four, I realized it was time to sleep train our son.
Raising a healthy sleeper starts with a consistent bedtime routine. You can start enforcing this when your baby is roughly six weeks old. At the same time every night, read a book together, sing songs, and feed your baby before putting him or her into the crib. It may also help to get your child up at the same time every morning and put him down for naps at regular times.
Fading, also known as adult fading or camping out, falls in the middle of the sleep training spectrum. In fading, parents gradually diminish their bedtime role by sitting near your baby until she falls asleep and gradually moving the chair farther away from the crib each night. Another fading approach is to check on your baby and reassure her (without picking her up) every five minutes until she falls asleep.
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.
The age of your baby might determine what kind of sleep-training method you choose, though. You could try a gentle shush-pat technique with a five-month-old, but you’ll likely have to leave a one-year-old in the crib as they protest (cry or scream) about the new bedtime arrangement. Don’t attempt a formal sleep-training method before four months, until your baby is able to go longer in between feeds and their circadian rhythm starts to develop. (Many babies this age still feed in the night—contrary to popular thinking, sleep training isn’t synonymous with night weaning.) Dickinson says that many four-month-old babies are biologically able to go through the night without a feed, but that doesn’t mean you shouldn’t respond and feed them if other methods of calming them aren’t working. Since every situation is different, we recommend checking with your doctor before withholding your baby’s night-time feeds.
