What the sleep score means and how to improve it

The Lulla Sleep Score is a number from 0 to 100 that tells you how well your baby slept today. It's not a judgment — it's a tool for understanding.

The 6 components

Duration (30 points) — How close the daily sleep total is to the WHO recommendation for your baby's age. A newborn needs 14-17 hours, a toddler 11-14 hours.

Consistency (20 points) — How steady the bedtime is. Variation under 30 minutes = full score. Over 2 hours of variation = 0 points.

Night/day ratio (15 points) — The ideal is 65-90% nighttime sleep. Too much daytime sleep can disrupt nights.

Quietness (10 points) — Fewer wake-ups = higher score. 0 wake-ups = 10/10.

Quality (15 points) — The rating you give at the end of each session (1-5 stars).

Mood (10 points) — How your baby wakes up. "Happy on waking" = 10/10. "Fussy" or "Crying" = lower score.

What's a good score?

• 85-100: Excellent — Congratulations! The routine is working perfectly.
• 70-84: Very good — Small adjustments can make the difference.
• 55-69: Good — The basics are solid, but there's room for improvement.
• 40-54: Could be better — Focus on the weakest component.
• Under 40: Needs attention — Read the personalized advice in Lulla.

3 quick strategies for +15 points

1. Keep the same bedtime (±15 min) for 7 days in a row — that's exactly what makes a solid bedtime routine.

2. Complete the review after every session — quality and mood are 25 free points.

3. Reduce afternoon naps if nighttime sleep is under 8 hours.
