Understanding Baby Sleep Cycles

Sleep is vital for immune function, brain plasticity, and physical growth. However, baby sleep cycles are much shorter than adults (50-60 minutes compared to 90-110 minutes).


The Wake-Sleep Rhythm

  • 0 to 3 Months: Babies do not produce sufficient melatonin yet. Day/night confusion is common.
  • 4 to 6 Months: Circadian rhythm stabilizes. Night sleep stretches lengthen to 5-6 hours.

Tips for Better Sleep:

  1. Expose your baby to natural sunlight during morning feedings.
  2. Maintain dim lighting and low noise levels during nighttime changes.
  3. Establish a calming sequence: warm sponge bath, gentle massage, lullaby, and bed.
