The Rhythm
of Sleep.

Every baby's rest is a masterpiece of biology. Welcome to an immersive journey through the science of your baby's night.

The Fourth
Trimester.

0–3 Months. Sleep is raw, erratic, and biologically untethered. In these first weeks, we do not follow schedules — we follow the soul.

The Dawn of
Routine.

4–12 Months. Circadian rhythms lock into place. The chaos settles into windows — periods of light and recovery that define your day.

The Sustainable
Rest.

12–24 Months. Consolidating into a single, deep midday pause. The transition from surviving the night to mastering the day.
