Why Does Bedtime Matter?

Babies need consistent sleep to support brain development, physical growth, and emotional well-being. Going to bed too late may cause your baby to become overtired, making it harder to fall asleep and stay asleep.

An appropriate bedtime can help:

  • Improve nighttime sleep quality
  • Reduce bedtime struggles
  • Support healthy growth and development
  • Encourage longer stretches of sleep
  • Establish a predictable daily routine
