It's 2 a.m., your baby is crying again, and every article you read seems to contradict the last one. Ferber and cry it out are the two sleep training methods parents ask about most, and they're often lumped together even though they work quite differently. Here's a clear, judgment-free breakdown of both, so you can decide what actually fits your baby — and you.
What Is the Ferber Method?
The Ferber method — also called "graduated extinction" or "check and console" — was popularized by pediatrician Dr. Richard Ferber. The core idea is simple: you put your baby down awake, leave the room, and return at timed intervals to briefly reassure them.
The check-ins get gradually longer, which is where "graduated" comes from. Your baby learns to fall asleep without being fed, rocked, or held — but you're never gone for long stretches, especially on night one.
How graduated check-ins work
- Do your usual calming bedtime routine, then put your baby in the crib drowsy but awake.
- Say goodnight and leave the room. If your baby cries, wait a short interval — often around 3 minutes on the first night — before going back in.
- Keep check-ins brief, about a minute. Use a calm voice and a quick pat or shush. Don't pick your baby up, feed, or turn on the light.
- Leave again and wait a slightly longer interval before the next check — for example 5 minutes, then 10.
- Each night, start with a longer first interval than the night before. Repeat until your baby falls asleep on their own.
The check-ins reassure your baby that you're nearby — and reassure you that your baby is safe and simply protesting a change, not in distress you can't see.
What Is Cry It Out (Extinction)?
Cry it out — researchers call it "extinction" or "unmodified extinction" — removes the check-ins entirely. After your bedtime routine, you put your baby down awake, say goodnight, and don't return until morning (or until a feeding you've planned to keep), unless something seems wrong.
That sounds harsh on paper, but there's a logic to it. For some babies, every check-in acts like a reset button: they calm briefly, then cry harder when you leave again. Removing the visits removes those resets, which is why extinction often works faster for babies who escalate when a parent appears.
To be clear: cry it out doesn't mean ignoring your baby. You still watch or listen on a monitor, and you still go in for anything that isn't ordinary protest crying — a stuck leg, a diaper blowout, coughing, vomiting, or signs of illness.
Ferber vs Cry It Out: Side-by-Side
Both methods teach the same skill — falling asleep independently. The difference is how you get there.
| Ferber (graduated check-ins) | Cry it out (extinction) | |
|---|---|---|
| Crying involved | Yes — typically moderate, tapering over several nights | Yes — often more intense at first, then tapering quickly |
| Parent presence | Brief timed check-ins that gradually lengthen | No check-ins after goodnight, except for safety |
| Typical timeline | Around 3–7 nights for many babies | Around 2–4 nights for many babies |
| Age suitability | Generally 5–6 months and up | Generally 6 months and up |
| Difficulty for parents | Easier for many — checking in feels like doing something | Harder to hold back, but often over sooner |
Every baby is different, so treat these timelines as rough patterns, not promises. Temperament, age, and how consistent you are all shift the picture.
What the Research Broadly Says
Behavioral sleep training is one of the most-studied topics in pediatric sleep, and the overall picture is reassuring for parents on either side of this choice:
- Both graduated extinction (Ferber) and full extinction have been studied for decades and are considered effective behavioral approaches for helping babies fall asleep and stay asleep in the contexts researchers have examined.
- Studies that followed families over time have not shown lasting harm to children's emotional wellbeing, behavior, or attachment to their parents in those studied contexts.
- Consistency matters most. Responding on some nights and not others teaches babies that crying longer eventually works — which usually means more total crying, not less.
- Sleep training changes what happens at bedtime. It doesn't change who you are all day: a warm, responsive parent.
Whichever route you take, always follow safe-sleep basics — the AAP's ABCs: baby sleeps Alone, on their Back, in a bare Crib. And if your child snores, has pauses in breathing, arches in pain after feeds, or tugs at an ear, talk to your pediatrician before starting any sleep training. These methods address habits, not medical issues.
Who Each Method Tends to Suit
Ferber may fit your family if...
- You want a structured plan but can't imagine going all night without checking.
- Your baby settles a little (or at least doesn't escalate wildly) when you appear.
- You can stick to the intervals — even at 1 a.m. when you're exhausted.
- You're starting with a baby around 5–6 months or older.
Cry it out may fit your family if...
- Your baby cries harder every time you enter and leave the room.
- You tried Ferber and the check-ins seemed to fire your baby up rather than calm them.
- You want the fastest route and both parents are fully on board.
- Your baby is at least 6 months old and growing well, per your pediatrician.
When neither is the right fit — yet
Hold off on both if your baby is under about 5 months, is sick or cutting a tooth right now, or is in the middle of a big change like starting daycare or a move. And if the idea of timed crying makes you dread bedtime, that's worth listening to — a method you can't follow through on will not work, no matter how effective it is on paper.
Gentler Alternatives if Neither Feels Right
You are not choosing between Ferber, cry it out, or endless sleepless nights. Several slower, more parent-present methods teach the same independent-sleep skill:
The chair method
You sit in a chair next to the crib while your baby falls asleep, offering calm verbal comfort. Every few nights, you move the chair farther from the crib until you're out the door. Less crying, more nights — usually a couple of weeks.
Pick up, put down
When your baby cries, you pick them up, calm them, and put them back down awake — as many times as it takes. This tends to work best under about 6–7 months; older babies often find the constant handling stimulating rather than soothing.
Fading
You gradually shrink your role in how your baby falls asleep — rocking a little less each night, or feeding earlier in the routine. A related approach, bedtime fading, temporarily moves bedtime later so your baby is sleepy enough to drift off fast, then inches it earlier.
These approaches involve fewer tears but ask for more patience and just as much consistency. We walk through each one step by step in our gentle sleep training guide, and you can see how all the major approaches stack up in our full comparison of sleep training methods.
How to Choose for Your Family
Match the method to your baby's temperament
- Adaptable, easygoing babies tend to do fine with almost any method. Pick the one you can follow consistently.
- Persistent, spirited babies who rage harder with every visit often cry less overall with fewer or no check-ins.
- Sensitive, slow-to-warm babies may do better with gradual, present methods like the chair method.
Be honest about your own capacity
The best method is the one you'll actually finish. Doing Ferber for two nights, then rocking to sleep on night three, then trying again on night five is harder on everyone than committing to a gentler method from the start. Choose based on the worst night you can imagine, not the best.
Set the stage before night one
Timing does half the work. An overtired baby fights sleep harder, and an undertired baby has no reason to drift off:
- Check that your baby's wake windows match their age, and use our bedtime calculator to land on a realistic bedtime.
- Make the room dark, use steady white noise, and keep a consistent 20–30 minute wind-down routine.
- Start on a night when you can absorb a rough stretch — many families pick a Friday.

Age notes at a glance
- Under 5 months: formal sleep training isn't recommended. Focus on routine, age-right wake windows, and full feedings.
- 5–6 months: Ferber-style check-ins are often appropriate with your pediatrician's okay; full extinction usually waits until 6 months.
- 6–12 months: the prime window for both methods. Separation anxiety around 8–10 months can add tears — consistency still wins.
- Toddlers: both methods can be adapted, but a toddler in a bed needs boundaries and buy-in, not just intervals — expect a slower, more verbal process.
FAQ
Is the Ferber method the same as cry it out?
No. Ferber uses timed check-ins that gradually get longer, so your baby is never alone for long stretches at first. Cry it out (full extinction) means no check-ins after goodnight, except for safety concerns. Both involve some crying, but the structure and pacing are different.
How long does the Ferber method take to work?
Many families see the biggest improvement within the first week, with nights two and three often being the hardest. Progress isn't always a straight line — a rough night four doesn't mean it's failing. If nothing has improved after about two weeks of truly consistent effort, reassess the schedule and the method.
Does cry it out cause long-term harm?
Studies that have followed sleep-trained children over time have not shown lasting harm to emotional development, behavior, or attachment in the contexts studied. What matters most is a responsive, loving relationship across the whole day. And if extinction doesn't feel right for your family, gentler methods teach the same skill — they just take longer.
What age can I start Ferber or cry it out?
Most guidance suggests waiting until at least 5–6 months for Ferber-style check-ins and around 6 months for full extinction. Before then, babies often still need night feedings and can't yet self-settle reliably. Check with your pediatrician first, especially if there are concerns about weight gain, reflux, or breathing.
What if my baby cries for hours?
First, recheck the schedule — a bedtime that's too early or too late is the most common reason sleep training stalls, so revisit wake windows and total daytime sleep. Rule out illness, teething pain, or discomfort, and call your pediatrician if anything seems off. If intense crying keeps forcing you to abandon the plan, switch to a more gradual method rather than applying a fast one inconsistently.
Can I use Ferber for naps too?
Yes, many families do, using the same check-in intervals with a time cap — if your baby hasn't fallen asleep after about 30 minutes, end the attempt and try again at the next sleep time. Naps usually take longer to improve than nights because daytime sleep pressure is lower. Some parents find it easier to sort out nights first, then tackle naps a week or two later.
