Your baby's next nap, predicted

Nap predictions built from your baby's data.

SweetSpot doesn't use generic age charts. It learns from every nap you log and tells you when your baby is most likely to fall asleep — and stay asleep.

Age charts are averages. Your baby isn't.

Every baby sleep article gives you the same chart: "6-month-olds need 2–3 hour wake windows." Great. Your 6-month-old falls apart at 1 hour 50 minutes. Or pushes to 2 hours 45 minutes without blinking.

You end up guessing. Sometimes the nap works. Sometimes you spend 40 minutes trying to put down a baby who isn't actually tired yet. Or you wait too long and now they're wired.

The real answer isn't what "most babies" do. It's what your baby did yesterday, and the day before, and the pattern that's forming from their actual behavior.

Predictions that learn from every nap

SweetSpot watches. Every time you log a sleep session — nap duration, wake window length, time of day, how easily they fell asleep — it feeds into a model of your baby's unique rhythm.

After a few days of tracking, SweetSpot starts predicting. "Based on the last week, your baby's next ideal nap time is around 1:15pm." It's not a fixed schedule. It shifts as your baby's patterns shift.

The predictions get sharper over time. Two weeks of data is better than three days. A month of data captures nap transitions and regressions the algorithm adapts to automatically.

Pattern recognition

SweetSpot identifies your baby's personal sleep rhythms — preferred nap lengths, optimal wake windows, time-of-day preferences.

Adaptive predictions

Predictions adjust as your baby grows. When they start stretching wake windows or dropping a nap, SweetSpot adapts.

Confidence notifications

Trend visibility

See whether predictions are getting earlier or later over time — an early signal of nap transitions or schedule shifts.

Real scenario

Week two

You've been logging for 11 days. SweetSpot shows a predicted nap at 12:40pm. You start the routine at 12:30. Your baby is asleep by 12:38. The predicted nap length: 1h 15m. Actual: 1h 22m. This isn't magic — it's your data, reflected back as a pattern you couldn't have seen on your own.

Built for

Babies with inconsistent schedules who don't fit the "typical" mold
Families navigating nap transitions (3→2, 2→1) who need data, not opinions
Parents who want to build a nap schedule around their baby's real biology, not a blog post

Common Questions

How quickly does SweetSpot start predicting?

SweetSpot can generate initial predictions after 3–5 days of consistent tracking. Accuracy improves significantly after 10–14 days as the algorithm has more data points to identify patterns.

Is SweetSpot just a wake window calculator?

No. A wake window calculator gives you a fixed number based on age. SweetSpot factors in nap duration, time of day, previous wake windows, and how they've been trending — then predicts the specific time your baby is most likely to fall asleep.

What happens during a sleep regression?

SweetSpot detects when patterns shift — shorter naps, longer wake windows, more variability. It adjusts predictions accordingly rather than sticking to a pre-regression schedule that no longer applies.

Is the SweetSpot feature free?

The core SweetSpot predictions are free. Premium unlocks more detailed prediction analytics and historical trend data.
