What Is Sleep Training, Really?
Sleep training refers to methods that help babies learn to fall asleep independently — and more importantly, to resettle themselves when they wake between sleep cycles. It doesn't mean leaving your baby to cry indefinitely, and it doesn't mean one single approach. There's a wide spectrum, and the "best" method is the one your family can follow consistently.
When Can You Start Sleep Training?
Most pediatricians suggest waiting until babies are at least 4–6 months old, as this is when sleep cycles begin to mature and the ability to self-settle develops. Before this age, night waking is biologically normal and important for feeding. Always check with your pediatrician before beginning any sleep training.
Popular Sleep Training Methods
1. The Ferber Method (Graduated Extinction)
Developed by Dr. Richard Ferber, this method involves placing your baby down drowsy but awake, then leaving the room. If they cry, you return to offer brief verbal reassurance at gradually increasing intervals (e.g., 3 minutes, then 5, then 10). You do not pick them up during check-ins. Most families see results within a week.
Best for: Parents who want a structured, time-limited approach and can tolerate some crying.
2. The "Cry It Out" Method (Extinction)
Also called the Weissbluth method. You put baby down drowsy but awake and do not return until morning (or the next scheduled feed). It often works quickly but requires confidence and consistency from parents.
Best for: Families ready to commit fully and who feel comfortable with the approach.
3. The Chair Method (Sleep Lady Shuffle)
You sit in a chair next to the crib, offering reassurance without picking up baby. Every few nights, you move the chair farther away until you're outside the room. It's slower than extinction methods but more presence-based.
Best for: Parents who want to stay present but still teach independent sleep.
4. The Fading / Pick Up, Put Down Method
When baby cries, you pick them up until calm, then put them back down. Repeat as needed. This is time-intensive but very gentle. Best suited for younger babies (4–6 months) as it can become overstimulating for older infants.
Best for: Parents who can't tolerate any extended crying and have patience for a slower process.
5. No-Cry Sleep Solution
Based on Elizabeth Pantley's book, this approach involves gradually adjusting sleep associations, moving bedtime earlier, and gently removing sleep props (like nursing to sleep) over time — with no intentional crying involved.
Best for: Families preferring a very gradual, attachment-based approach.

| Ferber | Yes, with check-ins | 3–7 days | Intermittent |
| Cry It Out | Yes, no check-ins | 2–5 days | None at night |
| Chair Method | Some | 1–3 weeks | Full then fading |
| Pick Up Put Down | Minimal | Weeks | Responsive |
| No-Cry | None intentional | Weeks to months | High |
Building Healthy Sleep Habits (Before You Even "Train")
Many families find consistent routines reduce or eliminate the need for formal sleep training:
- Consistent bedtime routine — bath, feeding, story, song in the same order each night signals sleep is coming.
- Early bedtime — overtired babies fight sleep harder. Most babies do well with a 6:30–8:00 pm bedtime.
- Drowsy but awake — putting baby down before they're fully asleep teaches them to fall asleep in their crib, not in your arms.
- Dark, cool room with white noise — minimizes waking from environmental stimuli.
A Note on the Research
Studies, including long-term follow-up research, have consistently found that sleep training methods — including those involving some crying — do not cause lasting emotional harm to babies when parents are otherwise responsive and loving. That said, every family is different. The method you can follow consistently is the one most likely to work.
