Baby Sleep Basics

Understanding Sleep Cycles

Babies have shorter sleep cycles than adults (about 50-60 minutes). They spend more time in active REM sleep, which is why they're more likely to wake easily.

Sleep Cues

Watch for signs your baby is tired: rubbing eyes, yawning, looking away, fussiness. Acting early on these cues prevents overtiredness.

Wake Windows

The time your baby can comfortably stay awake between sleeps varies by age. Following age-appropriate wake windows helps prevent overtiredness.

Consistent Routines

Establishing predictable nap and bedtime routines helps signal to your baby that sleep is coming, making transitions easier.

Frequently Asked Questions

"Sleeping through the night" varies by age. By 3-6 months, many babies can sleep 5-6 hour stretches. By 9-12 months, many can sleep 7-10 hours without feeding. However, sleep regressions and developmental leaps can temporarily disrupt sleep patterns.

Nap needs change with age:

  • 0-3 months: 4-5 naps
  • 3-6 months: 3-4 naps
  • 6-12 months: 2-3 naps
  • 12-18 months: 1-2 naps
  • 18 months-3 years: 1 nap

Sleep training refers to teaching your baby to fall asleep independently. Most pediatricians suggest waiting until 4-6 months when babies can physiologically go longer without feeding. There are multiple approaches (gradual, check-and-console, chair method, etc.) - choose one that fits your parenting style and your baby's temperament.
