When do babies sleep through the night?

Most babies can sleep through the night (6-8 hours straight) by 4-6 months of age with proper sleep training and routines. However, every baby is different. Newborns (0-3 months) wake every 2-3 hours for feeding. By 3-6 months, many babies can do 4-6 hour stretches. 90% of babies sleep through the night within 2 weeks of consistent sleep training. Keys to success: consistent bedtime routine, appropriate wake windows, self-soothing skills, and age-appropriate feeding schedule.

How much sleep does my baby need?

Baby sleep needs by age: Newborns (0-3 months) need 14-17 hours total with 3-5 naps; 3-6 months need 12-15 hours with 3-4 naps; 6-12 months need 12-14 hours with 2-3 naps; Toddlers (1-3 years) need 11-14 hours with 1-2 naps. Night sleep should be 9-12 hours for babies 3+ months. Wake windows (time between sleep) increase with age from 45-90 minutes for newborns to 4-6 hours for toddlers.

What is the best sleep training method?

Best sleep training methods include: Ferber Method (graduated extinction - check at increasing intervals 3-5-10 minutes, 85-90% success rate), Chair Method (gradual retreat, gentler approach), Pick Up/Put Down (responsive but teaches self-soothing), and Fading Method (slowly reduce parental involvement). Choose based on your parenting style and baby's temperament. Most methods work within 3-7 days with consistency. Start sleep training at 4-6 months when babies can self-soothe. Consistency is more important than the specific method.
