Sleeping through the night usually means a baby sleeps for a long stretch without waking, which research often defines as 6 to 8 hours. Night waking is normal in the first year, and many healthy babies still wake at night after their first birthday.

Key takeaways

  • Young babies need night feeds to grow.
  • There is a wide range of normal.
  • Brief waking between sleep cycles is normal at every age.

What you can do

  • Keep night feeds dark, quiet and calm.
  • Make day and night clearly different with light and activity.
  • Try not to compare your baby with others.
