• Weissbluth method. This sleep-training method suggests you set up a bedtime routine (bath, book, lullaby), then put baby to sleep, shut the door and don’t re-enter until the next morning. “I tried this, and the first night was awful,” says Jen, a mom of one, who did the Weissbluth method at 4 months. “I turned on the shower and sat in the bathroom so I wouldn’t hear my son cry. But I was watching the baby monitor and saw that after an hour, he found his thumb and fell asleep. The next night was maybe 40 minutes of crying, then 20 minutes the night after that. He’s always happy in the morning, and I feel this was the right choice.”
Remember that the human brain—yours and your baby's—runs on sleep. The American Academy of Pediatrics (AAP) has linked babies' frequent night wakings to everything from postpartum depression in moms to future obesity and behavior problems in kids. As Marc Weissbluth, M.D., the author of Healthy Sleep Habits, Happy Child, explains, children who don't get enough consolidated REM sleep have shorter attention spans, so they don't learn as well. These babies also release more of the stress hormone cortisol, setting them up for frequent night wakings and stunted naps. Tired yet?
This is another gentler technique. The PUPD method works just the way it sounds: when it’s time to sleep, and your baby is fussing or crying in his crib or bassinet, you pick him up and comfort him until he’s calm and drowsy. Then, you put him back in his crib to sleep, repeating this cycle until your baby is finally asleep. PUPD is another method that requires quite a bit of patience, depending on your baby, and it won’t work for every baby; some babies find being picked up and put down so often over-stimulating, and they gradually become frustrated and worked up, instead of relaxed.
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.
Parents often wonder how to know if your child needs sleep training or if their sleep habits are just something they’ll grow out of. If your baby is consistently cranky and overtired, it's probably time to look into helping them become a better sleeper. And as Melissa noted, she started sleep training the second time around because she could tell her son was just as frustrated as she was about not sleeping!
Most sleep coaches say the ideal time to start sleep training (or promote independent sleep, not necessarily using the cry-it-out method) is based on your baby’s development, but is usually somewhere between four and six months, when your baby hasn’t had much time to get used to nursing or rocking to sleep. At this stage, most babies are also developmentally ready to learn the skill of falling asleep on their own, explains Jennifer Garden, an occupational therapist who runs Sleepdreams in Vancouver. Around four months of age, some babies go through a sleep regression because their sleep cycles change and there are longer periods of lighter sleep per cycle. “It’s a great time to work on independent sleep skills,” says McGinn. Other babies’ slumber derails around this time because they are working on new skills, like moving around and rolling. Some parents choose to wait until things settle down before embarking on a sleep-training method, but you don’t have to, says McGinn.
