Five age bands
By age
The protocol is the same at every age. The day, the development pressure, and the stalling tactics are not. Pick the band that matches your baby.
Age band
Ferber at 6 months
What sleep looks like at six months, why this is the earliest age the app supports, what your Night 1 will probably look like, and the specific safety bar for this window.

Age band
Ferber at 7 to 9 months
The sleep changes between six and nine months, why this is often the easiest window for a Ferber arc, what the 8-month regression does to the timeline, and what an honest Night 1 looks like at this age.

Age band
Ferber at 10 to 12 months
How the introduction of walking, language, and stronger separation anxiety changes a Ferber arc. Why this window is more variable than the 7-9 month one, and what an honest Night 1 looks like at this age.

Age band
Ferber at 12 to 18 months

Age band
Ferber at 18 months and beyond
How the Ferber method adapts for an older toddler. The 18-month regression, the cot-to-bed transition, the role of negotiation and visual schedules, and an honest assessment of what the protocol can and cannot do at this age.
