What is the Ferber or “Cry It Out” Method of Sleep for Babies
The Ferber method is a sleep training approach that uses timed, gradually lengthening check-ins instead of soothing your baby immediately every time they wake. It is often described as “cry it out,” but Dr. Richard Ferber, who developed the method, has always emphasized that it’s more structured than that. His approach involves short check-ins at intervals that gradually increase, with the goal of teaching babies how to self-soothe while still receiving reassurance from their parents.
Since his 1985 self-help book titled “Solve Your Child’s Sleep Problems,” his strategies have been met with some resistance from parents. However, in a 2006 interview, Ferber clarified the intent of his method, noting that “It’s not just about leaving them to cry—it’s about gradually teaching them to settle without panic” (NPR). His updated reflection reframed the method as a balance of building independence while still offering consistent parental support.
Child and family development expert Ana Adame, M.A., an Ontario-certified educator with more than 20 years of experience in early childhood education and parent coaching, echoes this perspective. “Letting toddlers cry isn’t abandonment; it’s standing firm while they develop emotional wiring,” Adame explains, highlighting that co-regulation, where parents help toddlers calm down, lays the foundation for children to eventually self-regulate (Ana Adame).
When to Start Sleep Training
Most pediatricians recommend waiting until at least four to six months before trying the Ferber method, when babies are developmentally ready and cleared by a doctor. Starting too early, or during times when a baby is experiencing reflux or colic, can make the process more stressful for everyone involved (Sleep Foundation).
Modified Ferber for Breastfed Babies
Breastfeeding parents often worry about supply and night feeds. A modified approach allows for necessary feeds while still introducing gradual check-ins afterward (PedsDocTalk).
Ferber Nap Schedule vs. Bedtime Schedule
Parents frequently search for examples of nap and bedtime schedules. While Ferber can be used for both, naps are often harder because there are fewer chances for practice. Some families find it easier to start with bedtime first before introducing naps.
Combining Ferber with Co-Regulation
Parents who value attachment parenting often wonder if it’s possible to combine co-regulation with sleep training. The answer is yes: practicing co-regulation during the day while using a gradual Ferber approach at night creates balance.
Gentle Ferbererizing for Sensitive Babies
Not every baby responds to the same plan. Sensitive or high-needs babies may need “gentle Ferber” variations with shorter intervals, more frequent check-ins, and a slower timeline.
