Getting a baby to fall asleep comes down to three things: a consistent routine, the right environment, and helping your baby learn to drift off without being held or rocked the entire way. The specifics change as your baby grows, but the core principles work from the newborn stage through the first year and beyond.
Why Babies Wake So Often
Newborns sleep 16 to 17 hours a day, but they do it in stretches of just one to two hours at a time. Their sleep cycles are much shorter than yours, and every time they transition between cycles, there’s a chance they’ll wake up fully. By 4 to 12 months, total sleep drops to 12 to 16 hours, but the stretches get longer, especially at night.
Understanding this helps set realistic expectations. A six-week-old waking every 90 minutes isn’t broken. That’s simply how infant sleep works. The goal isn’t to eliminate night wakings entirely but to help your baby fall back asleep more easily when those between-cycle wakings happen.
Build a Short, Predictable Bedtime Routine
Babies thrive on repetition. A bedtime routine signals to your baby’s brain that sleep is coming, and it doesn’t need to be elaborate. Three to four steps in the same order every night is plenty: a warm bath, a fresh diaper and pajamas, a feeding, and a lullaby or short book. The whole sequence can take 20 to 30 minutes.
Start the routine at roughly the same time each evening. Consistency matters more than the exact activities you choose. Within a week or two, your baby will begin associating these steps with sleep, and the process of winding down will become faster and smoother.
Set Up the Room for Sleep
The ideal nursery temperature is between 68 and 72 degrees Fahrenheit. Overheating is both a sleep disruptor and a safety risk, so dress your baby in one layer more than you’d wear comfortably and skip the blankets.
White noise can be genuinely helpful. It mimics the constant whooshing sound babies heard in the womb and masks household noise that might startle them awake. Keep the volume below 50 decibels, which is about as loud as a quiet conversation, and place the machine at least two feet from the crib. Running it all night is fine, but louder isn’t better.
Darkness matters too. A pitch-black room encourages the production of sleep hormones. If you need light for nighttime feedings or diaper changes, a dim red or amber night light is less disruptive than white or blue light.
Learn the “Drowsy but Awake” Window
This phrase gets repeated constantly in baby sleep advice, and for good reason. The idea is to put your baby down when they’re sleepy but not fully asleep, so they practice the skill of falling asleep in the crib rather than in your arms. Watch for signs that your baby is getting drowsy: eye rubbing, a glazed-over stare, fussiness, or that heavy-lidded look where their blinks start getting slower.
If you wait too long and your baby is already asleep when you lay them down, they may startle awake during the transfer and need you to start the whole process over. If you put them down too early, they may not be tired enough to settle. It takes practice to find the sweet spot, and some nights you’ll miss it. That’s normal.
Sleep Training Methods That Work
Sleep training typically works best starting around 4 to 6 months, when babies are developmentally ready to sleep longer stretches. There’s no single right method. The best one is the one you can follow through on consistently.
Graduated Check-Ins (Ferber Method)
You put your baby down awake, leave the room, and wait a set number of minutes before going back in to briefly reassure them (without picking them up). Each night, the intervals get longer. On the first night, you wait 3 minutes before the first check, then 5 minutes, then 10 minutes for every check after that. By night seven, you’re waiting 20 minutes before the first check and up to 30 minutes between subsequent visits. Most families see significant improvement within three to five nights.
The check-ins are short, around one to two minutes. You can pat your baby’s chest or speak softly, but the goal is reassurance, not getting them to stop crying. Picking them up or feeding them during a check resets the process.
Pick Up, Put Down
This is a gentler option that involves more hands-on soothing. When your baby fusses or cries, you pick them up and comfort them. The key rule: as soon as their eyelids start to droop, you set them back in the crib. You repeat this cycle as many times as needed. It can take longer than graduated check-ins, sometimes requiring dozens of pickups in the first few nights, but some parents find it more comfortable than listening to extended crying.
Chair Method
You sit in a chair next to the crib while your baby falls asleep. Every few nights, you move the chair farther from the crib until you’re eventually outside the room. This works well for babies who just need to know a parent is nearby, though it requires patience since the full process can take two to three weeks.
What to Do About Sleep Regressions
Just when you think you’ve figured things out, your baby may start waking more frequently again. These regressions are tied less to specific ages and more to developmental milestones. The most common one starts around four months, when your baby’s sleep patterns are maturing and reorganizing. Others tend to happen when babies learn to roll over, pull themselves up, or crawl. They want to stay awake and practice their new skills, even at 2 a.m.
Most babies experience at least one regression in their first year. They typically last one to three weeks. The best approach is to stay consistent with whatever sleep routine you’ve established. Adding new sleep crutches during a regression, like bringing your baby into your bed or rocking them to sleep after they’d learned to self-settle, can create habits that outlast the regression itself.
Safe Sleep Basics
Every time your baby sleeps, whether for the night or a nap, safety matters. Always place your baby on their back on a firm, flat surface. The mattress shouldn’t indent when your baby lies on it, and any incline greater than 10 degrees is unsafe. Use a crib, bassinet, or play yard that meets Consumer Product Safety Commission standards, with a fitted sheet and nothing else inside. No pillows, blankets, stuffed animals, bumper pads, or weighted swaddles.
Products not specifically designed for infant sleep, like lounger pillows or baby nests, are not safe sleep surfaces regardless of how they’re marketed. If your baby falls asleep in a car seat, swing, or carrier, move them to a flat surface as soon as you can.
Room sharing, meaning your baby sleeps in your room but in their own crib or bassinet, reduces the risk of SIDS by as much as 50%. The AAP recommends this arrangement for at least the first six months. Bed sharing, where the baby sleeps in the same bed as a parent, is not recommended under any circumstances.
When Nothing Seems to Work
Some babies take longer to consolidate their sleep than others, and that variation is normal. If your baby is otherwise healthy, gaining weight, and alert during the day, a rough stretch of sleep is frustrating but not usually a sign of a medical problem. That said, persistent difficulty sleeping can sometimes point to reflux, food sensitivities, or ear infections, especially if your baby seems to be in pain or is arching their back during or after feedings.
The single most important factor in helping a baby sleep is consistency. Pick a routine and a method, give it at least a full week before deciding it isn’t working, and try to keep bedtime and wake time within the same 30-minute window every day. Babies don’t read the parenting books, so progress rarely follows a straight line, but the pattern almost always trends toward longer, more predictable sleep over time.
