Five methods, one neutral table. We sell no course, and we do not lead with the method that
happens to have the most marketing behind it: we lead with what the cited research and the
documented mechanics actually say, including two methods (chair method and pick-up-put-down)
that have never been isolated in a randomized controlled trial, which we say plainly rather
than inventing a number to make every row look equally studied.
We cite specific, checkable studies rather than a vague "research shows." All three are
peer-reviewed and independently retrievable.

Mindell JA, Kuhn B, Lewin DS, Meltzer LJ, Sadeh A. Behavioral treatment of bedtime problems and night wakings in infants and young children. Sleep. 2006;29(10):1263-1281.
An American Academy of Sleep Medicine task force review of 52 treatment studies. Across the studies reviewed, 94% reported behavioral interventions (including unmodified/graduated extinction and preventive parent education) were efficacious, with over 80% of treated children showing clinically significant improvement maintained at 3 to 6 month follow-up. Unmodified extinction and parent education carried the strongest evidence rating under the review's own criteria.

Gradisar M, Jackson K, Spurrier NJ, et al. Behavioral Interventions for Infant Sleep Problems: A Randomized Controlled Trial. Pediatrics. 2016;137(6):e20151486.
A randomized trial of 43 infants (6 to 16 months) assigned to graduated extinction, bedtime fading, or a sleep-education control. Both graduated extinction and bedtime fading reduced how long it took babies to fall asleep; graduated extinction also reduced night wakings. Morning and afternoon saliva cortisol (a stress marker) showed small-to-moderate declines, not increases, in both treatment groups versus control. At 12-month follow-up there were no differences between groups in emotional/behavioral problems or in secure-versus-insecure attachment style.

Price AMH, Wake M, Ukoumunne OC, Hiscock H. Five-Year Follow-up of Harms and Benefits of Behavioral Infant Sleep Intervention: Randomized Trial. Pediatrics. 2012;130(4):643-651.
A 5-year follow-up of 326 children whose parents received brief behavioral sleep consultations (including graduated extinction options) at 7 to 10 months of age versus usual care. At age 6, the study found no measurable long-term harms or benefits on child emotional/behavioral outcomes, the parent-child relationship, or child mental health, either direction. The authors concluded clinicians and parents can use these techniques for short/medium-term relief without evidence of lasting harm.

Night 1: after the bedtime routine, put baby down awake in the crib and leave. If baby cries, wait a set first interval (commonly 3 minutes) before a brief check: 1 to 2 minutes, low light, low voice, no picking up unless there is a safety concern, then leave again. If crying continues, the interval lengthens (a common schedule is 3, 5, then 10 minutes, repeating the longest interval) until baby falls asleep. The same lengthening schedule applies to overnight wakings, not just bedtime. Night 2 onward: the starting interval increases (for example starting at 5, then 10, then 12 minutes), so checks get less frequent as nights go on, and the schedule is applied consistently at bedtime and every overnight waking judged not to need a feed or a diaper change.
Who tends to pick this: Parents who want a structured middle ground: less crying-alone time than full extinction, but a faster, more decisive timeline than chair method or bedtime fading, and who can tolerate some crying without intervening beyond a brief check.
Where it commonly goes wrong: Caving and picking baby up mid-interval on a bad night, which some clinicians describe as reinforcing the most intense crying (baby learns the loudest protest is what works), often extending the overall timeline.
Method documented in: Richard Ferber, Solve Your Child's Sleep Problems (revised ed.), the method's namesake clinical text. Interval schedules vary by source and by age; the schedule above is a commonly cited illustrative version, not a single universal prescription. This site's plan builder lets you choose your own starting interval.
Full guide on Graduated Extinction → After the bedtime routine, put baby down awake in the crib, leave, and do not re-enter for crying alone, at bedtime or for overnight wakings, until a pre-agreed feed time (if still feeding overnight) or morning. A baby monitor stays on throughout so a parent can distinguish ordinary protest crying from a genuine problem (illness, an arm stuck in crib slats, vomiting) that warrants going in regardless of the plan. There is no lengthening-interval schedule to track, which is the whole appeal and the whole difficulty: it is the most decisive version of extinction and also the one with no built-in reassurance step.
Who tends to pick this: Parents who have already tried a slower method without success, want the shortest total number of difficult nights, and are comfortable with zero in-room reassurance once the plan starts, often on a caregiver's advice or after reading Weissbluth's or similar unmodified-extinction literature.
Where it commonly goes wrong: Going in partway through, which most sleep-training guidance flags as likely to extend, not shorten, the number of difficult nights, because the crying is intermittently reinforced.
Method documented in: Marc Weissbluth, Healthy Sleep Habits, Happy Child, one of the most widely read unmodified-extinction texts. The Mindell 2006 AASM review's strongest evidence rating (highest tier under the review's own grading) applied to unmodified extinction specifically, among the approaches it assessed.
Full guide on Full Extinction → Night 1 to 2 or 3: place a chair right next to the crib. Complete the bedtime routine, put baby down awake, and sit in the chair. If baby cries or fusses, you can shush or pat briefly without picking baby up, but keep interaction minimal and avoid eye contact that can re-stimulate rather than settle. Stay until asleep. Every few nights, move the chair farther away (toward the door, then just outside the doorway, then out of sight), repeating the same routine at that new distance until baby falls asleep unassisted at each step. The total timeline is directly a function of how many chair positions you use and how many nights you hold at each one.
Who tends to pick this: Parents with a low tolerance for baby crying alone, or a strong preference to remain physically present throughout, who are willing to trade a slower, less-studied timeline for less in-the-moment distress.
Where it commonly goes wrong: Moving the chair too fast, which can restart protest crying because the distance jump feels sudden to the baby rather than gradual.
Method documented in: Widely documented in parenting/sleep-consultant literature (e.g. Kim West's 'The Sleep Lady' shuffle) rather than a single peer-reviewed RCT. Honest gap: unlike graduated extinction, full extinction, and bedtime fading, chair method has not been isolated and measured in a randomized controlled trial the way the three studies above are cited for those methods. Its mechanics are well documented across sleep-consultant practice, but no RCT-level 'typical nights to resolution' figure exists to cite here, so this row's timeline range is a commonly cited practitioner estimate, not a study finding, and is labeled accordingly.
Full guide on Chair Method → After the bedtime routine, put baby down awake. If baby cries, pick baby up and comfort (hold, pat, shush) only until calm, not until asleep, then put back down awake again. Repeat every time crying restarts, for as many repetitions as it takes. The core discipline is putting baby down while still awake or only lightly settled each time, never waiting until baby is fully asleep in your arms, since the point is to build the skill of settling in the crib rather than being held to sleep. This tends to involve far more physical up-and-down repetition per night than graduated extinction's brief checks.
Who tends to pick this: Parents who want hands-on, in-arms comfort available every time baby cries and are comfortable with a physically demanding, often slower process in exchange for more direct comforting than chair method offers.
Where it commonly goes wrong: Rocking or holding baby until fully asleep before putting down, which undercuts the method's actual mechanism (baby learning to finish settling in the crib) and can stall progress indefinitely.
Method documented in: Popularized by Tracy Hogg, Secrets of the Baby Whisperer, and widely documented in subsequent sleep-consultant guidance. Same honest evidence gap as chair method: no RCT has isolated PUPD's own success rate or typical timeline, so the range shown is a practitioner estimate, not a study finding.
Full guide on Pick-Up-Put-Down (PUPD) → Track baby's real sleep onset for a few nights (a simple sleep diary) to find the time baby is genuinely drowsy and tends to fall asleep with little protest, even if that is later than the 'ideal' bedtime. Move bedtime to that observed time first, so the early nights are easy by design: baby is tired enough to settle with minimal or no crying. Once baby is reliably falling asleep quickly and with little fuss at that time for several nights running, shift bedtime 10 to 15 minutes earlier every few nights, holding each new time until it is also easy, until you reach the target bedtime. Because it works with baby's existing sleep pressure rather than against it, this is the method in this comparison most associated with low or no crying, at the cost of a slower, later-starting path to an earlier bedtime.
Who tends to pick this: Parents who want the lowest-crying option in this comparison and can tolerate a slower, multi-week process, or families for whom an existing bedtime is genuinely too early relative to baby's real sleep drive.
Where it commonly goes wrong: Moving bedtime earlier too fast (more than about 15 minutes every few nights), which can reintroduce the exact bedtime protest the method is designed to avoid.
Method documented in: Directly studied (alongside graduated extinction) in Gradisar et al. 2016, Pediatrics. Of the five methods here, bedtime fading has the most direct single-study evidence tying it specifically to a controlled comparison against graduated extinction, rather than being folded into a broader 'behavioral interventions' category the way Mindell 2006 treats several approaches together.
