Every parent has questions
You don’t have to figure this out alone
“Am I doing something wrong?”
Most difficult nights are not a parenting failure. They are a timing problem. Luli tracks your baby’s actual sleep patterns and shows you what is really happening — so the next step feels clear instead of like another guess.
“I can’t remember the last time I actually slept.”
Keeping wake windows, nap times, and feeding schedules in your head is not realistic on broken sleep. Luli remembers everything for you. You just check the app.
“Everyone has different advice and none of it is working.”
Generic sleep advice is written for average babies. Yours is not average. Luli builds predictions from your baby’s age, wake time, and actual logged sleep — not someone else’s schedule.

How does Luli predict the next nap?
Luli predicts the next nap using wake windows — the age-appropriate awake periods between sleeps — combined with your baby's logged sleep history. Predictions become more accurate as more sleep is logged.
