Welcome, you're not alone

If you got here with dark circles under your eyes, a forgotten cold coffee somewhere, and the feeling that everyone else can handle this except you, breathe. The first thing this course wants to tell you is simple: baby sleep is hard because it truly is hard, not because you're doing something wrong.

Babies aren't born knowing how to sleep the way we do. Their sleep is biologically different from adult sleep: the cycles are shorter, the share of light sleep is larger, and the internal clock that separates day from night is still under construction in the first months. That means waking up several times, sleeping in short blocks and mixing up night and day are not defects in your baby, nor failures of yours. They're the phase. An exhausting, real phase that weighs on your body and your mind, but a phase.

And there's another layer nobody warns you about: comparison. The cousin whose child "slept through the night at two months," the influencer's video of a baby who drifts off alone in the crib, the hunch that "back in my day you just let them cry." Every baby has a temperament, an age, a context. Comparing your baby to other people's babies is comparing two different stories while expecting the same ending. It doesn't work, and it only manufactures guilt.

What does work is the path this course will walk with you: first understanding how baby sleep really works, then acting through small, possible changes, and finally getting through the common problems without despair. Two weeks, one step a day, at your pace. Missed days aren't lost: everything you open stays available.

There's no new technique today, on purpose. Today is the day to take the weight off your shoulders. You are not behind, you are not failing, and you are not alone. You are raising a human being who is still learning one of the most complex things in early life: how to sleep.

Agreeing on expectations at the start prevents frustration at the end. So let's agree on everything honestly right here on day 1.

What this course is: a 14-day educational program about baby sleep, written in simple language and made to fit into the life of someone who isn't sleeping. The content is based on the guidelines of organizations such as the WHO, the Brazilian Society of Pediatrics and the American Academy of Pediatrics. This course does not replace the guidance of your baby's pediatrician. One short lesson per day, always with a central idea and one concrete action to try today. By the end, you'll understand your baby's cues, build a routine that works for your home, and know what to do (and what not to do) on the hard nights.

What this course is not: a promise. No serious person can guarantee that "your baby will sleep through the night in X days," because every baby has their own timing, and promises like that break exactly when you most need support. It's also not a rigid method with rules to follow to the letter: here you'll find options and paths, and the person who chooses what makes sense for your family is you.

And most importantly: this course is not medical care. It informs, supports and organizes, but it doesn't diagnose or prescribe. If at any moment you notice something concerning about your baby's health, such as fever, refusing to feed, weight loss, frequent vomiting, pauses in breathing during sleep, or anything your instinct says isn't right, see your child's pediatrician. Always. The pediatrician knows your baby; we know sleep in general. The two complement each other, they never replace each other.

If you're in for this deal, honesty instead of miracles, we walk together for the next 13 days.

This course lives inside Naplet for a reason: the lessons are worth more when they meet your own baby's data. Theory explains babies' sleep; the app shows your baby's.

Over the next days, several lessons will ask you to look at a pattern: how long the baby stayed awake before the nap, how many naps they took, how the night went. For that pattern to exist, it has to be logged. And that's where the simplest and most powerful habit of this course comes in: logging sleep in the app, in one tap, every time.

It doesn't have to be perfect. Forgot to log a nap? That's fine, log the next one. The goal isn't a flawless journal, it's an approximate map that, within a few days, starts to tell a story: "ah, he always crashes at 1pm," "the bad nights come after days without naps." That map is what will turn the course's concepts into practical decisions for your baby, by name.

How to do it, in 30 seconds: on Naplet's Home screen, when the baby is going to sleep, tap Start Sleep. When they wake up, tap Wake Up. That's it. The app takes care of the rest: it adds up the day's total, counts the naps, and keeps the history we'll use together starting on day 4, when we talk about wake windows (and you'll see that Naplet calculates your baby's window on its own).

One last thing about the course's pace: a new day opens with each calendar day, and days already opened stay open forever. If the night was chaos and you skipped two days, there's nothing to "catch up on," no broken streak, no guilt. The course waits for you. Your life sets the pace, not the app.
