Overview of Sleep Training

Sleep training refers to the process of teaching babies to fall asleep independently and stay asleep through the night. There are several evidence-based methods ranging from gentle approaches to more structured techniques. Most experts recommend beginning sleep training between 4-6 months of age, when babies have developed the ability to self-soothe and no longer require nighttime feedings.

Key Sleep Training Methods

1. The Cry It Out Method (CIO)
– Description: Also known as extinction, this method involves putting the baby down to sleep awake and leaving the room, not returning until morning regardless of crying.
– Process: Parents complete a bedtime routine, put baby down awake, and do not respond to crying.
– Benefits: Can work quickly (often within 3-7 days).
– Considerations: Emotionally difficult for many parents; concerns about potential stress on the baby.
– Research: Studies have found no evidence of long-term negative effects on children’s emotional health, behavior, or attachment to parents.

2. The Ferber Method (Graduated Extinction)
– Description: A more gradual approach where parents check on their crying baby at progressively longer intervals.
– Process: Put baby down awake, then check at set intervals (e.g., 5, 10, 15 minutes) with brief comfort but without picking up the baby.
– Benefits: Provides reassurance to both baby and parents; generally effective within a week.
– Considerations: Checking in may stimulate some babies and make crying worse.
– Research: Studies show improvements in infant sleep, parent sleep, and maternal mood with no negative effects on parent-child attachment.

3. The Chair Method (Sleep Lady Shuffle)
– Description: A gradual withdrawal approach where parents sit beside the crib and slowly move farther away over time.
– Process: Sit in a chair next to the crib until baby falls asleep, gradually moving the chair farther away each night until out of the room.
– Benefits: Allows parents to provide presence and reassurance without direct intervention.
– Considerations: Can take 1-2 weeks; may be difficult for parents to watch baby cry without intervening.
– Research: Effective but typically takes longer than other methods.

4. The Fading Method (Camping Out)
– Description: Parents gradually reduce their involvement in helping the baby fall asleep.
– Process: Continue using current soothing techniques (rocking, feeding, etc.) but gradually reduce the time spent doing them.
– Benefits: Very gentle approach; minimal crying.
– Considerations: Can take several weeks to see results; requires consistency.
– Research: Shown to be effective with minimal stress on babies and parents.

5. Pick-Up/Put-Down Method
– Description: A responsive approach where parents pick up crying babies to soothe them, then put them down again when calm but still awake.
– Process: Put baby down awake; if crying, pick up to soothe, then put down again before fully asleep. Repeat until baby falls asleep.
– Benefits: Responsive to baby’s needs; builds trust.
– Considerations: Can be exhausting; may take weeks to see results.
– Research: Effective but requires significant patience and consistency.

6. Respectful Sleep Training (No-Cry)
– Description: Focuses on creating a secure attachment while gently guiding babies toward independent sleep.
– Process: Respond to baby’s cues, create consistent routines, and gradually help them learn to fall asleep independently.
– Benefits: Minimal crying; respects baby’s emotional needs.
– Considerations: Requires significant time and commitment; may take months to see results.
– Research: Limited formal research, but anecdotal evidence suggests effectiveness for families prioritizing minimal crying.

7. Customized Sleep Training
– Description: Working with a sleep consultant to develop a personalized approach based on the baby’s temperament and family values.
– Process: Combines elements of various methods tailored to the specific family situation.
– Benefits: Personalized support; adaptable to family needs.
– Considerations: Can be costly; success depends on the consultant’s expertise.
– Research: Individual results vary, but consistency in application is key to success.

Key Principles for Successful Sleep Training

1. Timing: Most experts recommend waiting until 4-6 months of age.
2. Consistency: Using the same approach consistently is crucial for success.
3. Bedtime Routine: Establishing a consistent, calming bedtime routine signals to babies that sleep time is approaching.
4. Sleep Environment: Creating a safe, comfortable sleep space optimizes conditions for sleep.
5. Health Considerations: Ensuring baby is healthy before beginning sleep training.
6. Parental Readiness: Parents should be emotionally prepared and in agreement about the approach.
7. Flexibility: Being willing to adjust methods based on the baby’s response.

Sleep Patterns by Age

Newborns (0-3 months)
– Sleep 14-17 hours total per day
– No established sleep pattern; sleep in 2-4 hour segments
– Not developmentally ready for sleep training

4-6 months
– Sleep 12-15 hours total per day
– Beginning to develop circadian rhythms
– May be ready for gentle sleep training
– Often capable of sleeping 6+ hours at night

6-12 months
– Sleep 11-14 hours total per day
– Typically take 2-3 naps
– Most babies can sleep through the night (8-10 hours)
– Optimal time for sleep training if not started earlier

Toddlers (1-2 years)
– Sleep 11-14 hours total per day
– Usually transition to one nap
– Sleep training methods can still be effective but may require modification
