Four Methods, One Clear Path

Not one-size-fits-all. Four methods matched to your family.

Every sleep training guide picks a side. This one doesn't. CribNotes presents all four evidence-based methods, explains the tradeoffs, and helps you choose based on your cry tolerance, your timeline, and your actual life.

A

Graduated Extinction (Ferber)

10–14 days · 70–80% success

Check-in sleep training with increasing intervals. Most studied method. Fastest results. Best for parents who want it done in two weeks.

B

Timed Checks

10–16 days · ~70% success

Fixed check-in intervals — same time every night. Predictable and consistent. Easier to coordinate when partners disagree on the approach.

C

Bedtime Fading

4–6 weeks · ~80% success

No extinction crying. Move bedtime earlier until it aligns with your baby's natural sleep window. Slower, gentler, and highly effective.

D

Gentle / Camping-In

6–12 weeks · 60–70% success

Stay in the room and gradually reduce your physical presence over weeks. Most supportive. For sensitive babies and philosophy-based preferences.

Common Questions

What parents ask before buying

When should I start sleep training?
The American Academy of Pediatrics sets the developmental floor at 4 months (16 weeks corrected for preemies). Cognitive readiness for cry-based methods is typically 5–6 months. Weight matters more than calendar age — babies should be at least 12–13 lbs. The guide includes an 8-item readiness checklist to confirm your baby is ready before you begin.
How is this different from Taking Cara Babies or Huckleberry?
Taking Cara Babies costs $249 and teaches one approach. Huckleberry is $59–120/year. CribNotes is $27 one-time and gives you all four evidence-based methods so you can choose — plus a decision framework to guide the choice. It's also written by a physician (not a certified sleep coach) and explicitly cited against AAP 2024 guidelines.
My baby is already 10 months. Is it too late?
Not at all. Sleep training works at any age in the 4–12 month window. Earlier training tends to go faster (fewer entrenched habits), but 10-month-olds absolutely respond to all four methods. The guide includes protocol notes for later starters.
We're room-sharing. Can we still sleep train?
Yes. Chapter 12 covers room-sharing specifically. Extinction methods work in shared rooms but take slightly longer; Camping-In is often the most practical option. Expect 4–6 weeks rather than 2. The guide walks through physical setup, sound management, and partner coordination for shared spaces.
How long until it works?
Graduated Extinction (Ferber): most babies show meaningful improvement by nights 4–5; full consolidation by nights 10–14. Timed Checks: similar. Bedtime Fading: 4–6 weeks to see full benefit. Gentle/Camping-In: 6–12 weeks. The Night-by-Night Tracker template helps you measure progress objectively.
