When to Start Sleep Training
Most experts recommend waiting until at least 4–6 months when babies are developmentally ready and have established healthy sleep foundations.
Important Prerequisites
- Baby is at least 4–6 months old
- Healthy weight gain and no medical issues
- Consistent bedtime routine in place
- Parents are ready for a few difficult nights
Cry It Out (Extinction)
The most direct method: put baby down awake and do not return until morning (except for safety checks).
- Pros: Fast results (often 3–7 nights), clear boundaries
- Cons: Emotionally difficult for parents, not suitable for all families
- Best for: Babies 6+ months with no anxiety issues
Ferber Method (Check & Console)
Graduated extinction: check on baby at increasing intervals without picking up.
- Pros: More supportive than pure CIO, still effective
- Cons: Can still involve significant crying

Gentle Sleep Training Methods
Methods that minimize crying through fading techniques, pick-up/put-down, or fading the parent out gradually.
Pick Up / Put Down
Pick baby up when crying, soothe, then put down again. Repeat as needed.
Chair Method / Camping Out
Parent sits in a chair next to the crib and gradually moves the chair farther away each night.
