Leap and Teething Tracker for Fussy Weeks

Estrelu's leap and teething tracker helps parents get through rough weeks without wrecking their baby's sleep forecast. You mark a day as teething, illness, a growth spurt or a shot, and the forecast widens its range instead of learning from the chaos. It runs in your browser, works offline, and has no ads.

When the week stops making sense

Naps were finally predictable. Then your baby starts chewing everything, waking at night and fighting every nap. Most sleep apps keep learning from those days and give you strange predictions for weeks. In Estrelu, you tap "Off day," pick teething, and the forecast stays calm and honest about its uncertainty.

How the leap and teething tracker works

1. Tap "Off day." It's one of the extra buttons on the home screen.
2. Pick what's going on. Choose illness, teething, growth spurt or shot.
3. Keep logging as usual. The sleep forecast does not learn from these days and shows a wider range, so you know it's less sure.
4. Let it end on its own. The mark expires after 14 days. Your forecast goes back to learning from normal days.
5. Check fussy weeks. Based on your baby's age, Estrelu suggests when a harder week may come, so a rough patch is less of a surprise.

A typical leap app vs Estrelu

What it's based on and what it doesn't do

The fussy weeks feature is a rough age-based guide. It is not a medical fact, and your baby may not follow it. Every baby develops on their own timeline. The point is to give you a little warning and a reason to be patient with yourself, not a prediction to plan your life around.

What Estrelu does not do:

• It does not diagnose teething, illness or developmental problems.
• It does not predict the exact date of a leap or a new tooth.
• It does not suggest teething remedies or medicine doses.

If your baby has a fever or needs medicine, log it in the fever and medicine log. You'll see the time of each dose and when the next one is allowed. To see how off days affect naps, read about the baby sleep tracker. Travel or a clock change coming up? The time change and jet lag guide helps you shift sleep step by step.

When to call your pediatrician

Call your baby's doctor right away if your baby is younger than 3 months and has a temperature of 100.4°F (38°C) or higher (AAP). Also call if your baby seems unusually sleepy or limp, refuses to feed, has fewer wet diapers, or has a cry that sounds weak, high-pitched or different from usual. Don't assume a fever or rash is "just teething." When in doubt, call.

Estrelu is not a medical device. It does not diagnose, calculate doses or replace advice from your doctor.
