In the hazy, beautiful days of new parenthood, your baby's sleep can feel like a complex puzzle. Are they sleeping too much? Too little? This tool is designed to bring clarity and confidence to your journey. By tracking your baby's sleep patterns, you can gain a clearer picture of their unique needs and see how they compare to general pediatric guidelines. This isn't about enforcing a strict schedule, but about understanding your baby's natural rhythm.

How to Use the Sleep Tracker & Calculator

Our tool helps you log your baby's sleep and analyze their patterns in two simple steps:

  1. Log Sleep Sessions: Use the tracker throughout the day to record when your baby falls asleep and when they wake up. Log both naps and nighttime sleep over a full 24-hour period.
  2. Analyze the Results: Enter your baby's age. The tool will then calculate the total hours of sleep and compare this to the recommended range for their age. It will also show you the average duration of their 'wake windows' between sleep sessions.

Baby Sleep Needs by Age: A General Guideline

Remember, every baby is different, but these ranges from the American Academy of Pediatrics can be a helpful guide. This includes naps and nighttime sleep.

The Magic of 'Wake Windows'

One of the most helpful concepts in baby sleep is the 'wake window'—the amount of time a baby can comfortably stay awake between naps. Putting your baby down for a nap *before* they get overtired can make it much easier for them to fall asleep and stay asleep. An overtired baby is often a fussy, wired baby. Use your tracker to see what your baby's average wake windows are, and compare them to these typical ranges:

  • Newborn to 2 months: 45 - 90 minutes
  • 3 to 5 months: 1.5 - 2.5 hours
  • 6 to 8 months: 2 - 3 hours
  • 9 to 12 months: 3 - 4 hours

Tips for Building Healthy Sleep Habits

You can gently encourage healthy sleep from the early days with a few key strategies:

  • Create a Consistent Bedtime Routine: A simple sequence of events (like bath, pajamas, feeding, story) signals to your baby that sleep is coming.
  • Optimize the Sleep Environment: A dark, cool room with a white noise machine can help mimic the womb and block out household sounds.
  • Learn Your Baby's Sleepy Cues: Watch for early signs of tiredness like yawning, staring into space, or rubbing their eyes. Try to put them down for sleep when you see these cues.

Important Medical Notes

This tool is a guide based on averages and is for informational purposes only. Trust your instincts. If your baby seems unusually fussy or lethargic, is feeding poorly, or if you have any serious concerns about their sleep or your own well-being, please consult your pediatrician.
