# The Ferber method explained: how it works and whether it works > With the Ferber method (graduated extinction, or timed checks) you lay your baby down awake, leave, and come back for short checks at growing intervals… Source: https://actuallysleeping.net/guides/ferber-method-explained/ Publisher: Actually Sleeping LLC · Reviewed by Dr. Samantha Abrahamson, PharmD (PA pharmacist license RP1012588, NPI 1730650979) In the Ferber method — also known as graduated extinction or timed checks — you lay your baby down awake, step out of the room, and come back for short checks at steadily longer intervals until they fall asleep. Randomized trials in babies 6 to 16 months support it. Because you keep checking, it isn’t cry it out, but it does involve crying, and it isn’t right for every baby. **Up at 3 a.m. reading this?** Tonight doesn’t have to be a repeat. Actually Sleeping writes a plan around your baby, coaches you intensively before night one so you walk in confident, and checks in with you 1:1 every day until they are sleeping through — all backed by a full-refund guarantee.

Once the bedtime routine is done, your baby goes into the crib awake and you walk out. If your baby cries, you pop back in briefly at preset intervals that grow longer across the night and across the week; you can offer a calm word, but you don’t pick your baby up or feed them to sleep. Night wakings follow the same script, except for any planned feeds. ## What the research shows A review of 52 studies carried out for the American Academy of Sleep Medicine found support for graduated extinction, though the strongest support went to unmodified extinction and preventive parent education. In a 2016 randomized trial involving 43 babies aged 6 to 16 months, graduated extinction led to large drops in how long babies took to fall asleep and how often they woke at night, compared with a control group. Infant cortisol fell by a small-to-moderate amount relative to controls, and after 12 months the groups showed no differences in emotional or behavioral problems or in attachment. In other words, the method can work. What a parent really needs to know is whether it suits this particular baby, in this family, at this moment. ## Where it tends to break down, and why - **Babies who get more upset with each check.** For some babies, seeing a parent arrive and then leave is more distressing than not seeing them at all — yet the script keeps sending you back in. - **Parents who know they’ll pick up after a long stretch of crying.** Holding out for 40 minutes before rocking to sleep teaches a baby to cry for 40 minutes. - **Babies whose schedule is working against them.** An overtired or under-tired baby will protest whatever method you use. The intervals don’t correct the timing. - **Babies whose night-feed needs aren’t clear.** A script can’t distinguish a hungry waking from a habit waking. Which feeds remain depends on the baby’s age, and that’s not something a script can decide. - **Families who only use it at bedtime,** then feed or rock back to sleep later on. - **Young babies, or any baby who is unwell.** The trial evidence comes from babies 6 months and older. Ferber is a one-size script. It knows nothing about your baby’s temperament, feeds, bedtime or room — and those count for as much as the intervals do. ## What we do differently At Actually Sleeping, we don’t give you an interval chart. Dr. Sam writes a plan for your baby based on a detailed intake covering age, feeding, temperament, how your baby currently falls asleep, and your family’s schedule. It’s not cry it out, and it’s not wait it out. Bootcamp-style coaching before night one means you already know how to handle the decisions that typically derail timed checks. Daily 1:1 check-ins adjust the plan as your baby responds, and we coach naps until they’re solid. We put the result in writing: We guarantee that your baby will sleep 8–12 hours through the night within 14 days of consistent, correct implementation of your sleep plan. If not, you get a full refund. Plenty of families reach us after a check-based approach stalled; you can hear them in our [reviews from families who had already tried other sleep training](https://actuallysleeping.net/reviews/tried-other-methods/). ## Safe sleep, whichever method you choose As the AAP advises, your baby sleeps on their back, alone, on a firm, flat, non-inclined surface with no soft bedding. Always go in if your baby is ill, vomiting, or sounds different from ordinary protest. Check with your pediatrician about night feeds before you change anything. If you’d prefer not to run a script and hope it suits your baby, book a free consultation and Dr. Sam will show you what a plan built for your baby would look like. ## Keep reading - [The pick-up-put-down method: does it actually work?](https://actuallysleeping.net/guides/pick-up-put-down-method/) - [How quickly does sleep training work?

The trial evidence on graduated extinction comes from babies aged 6 to 16 months. Lots of younger babies still need to feed overnight, so talk to your pediatrician first. Actually Sleeping works with babies and toddlers, beginning with newborn foundations, and matches each plan to your baby’s age. ### Are Ferber and cry it out the same thing? No. With Ferber, you go back in for short, timed checks. With cry it out — unmodified extinction — you don’t go back in until morning, other than for planned feeds and safety. ### How long until the Ferber method works? That depends on the baby, the schedule and how consistently it’s used, and naps generally take longer than nights. A script can’t promise your baby a timeline, since it has no knowledge of your baby’s feeds, schedule or temperament. ### What if checking in makes my baby cry harder? Some babies react that way, and it signals that the script isn’t a good fit for them. Changing methods from one night to the next only makes it worse. Actually Sleeping handles a baby who escalates with checks through a plan written for that baby and adjusted every day. ## References 1. [Mindell JA, et al.
