Why doesn't my newborn sleep?
⚡ Short answer: Newborns waking frequently is developmentally normal and the main reasons are their tiny stomach capacity, short sleep cycles, and their not yet developed day-night rhythm.

In my first year of motherhood, this is what I wonder about most: why doesn't my baby sleep as a newborn?

The fact that newborns don't have a regular sleep schedule is both common and developmentally expected. Your baby's interrupted sleep has several basic reasons:
- Tiny stomach capacity: They get hungry every 2-3 hours, which causes frequent night waking.
- Short sleep cycles: Newborns cycle between REM (active) and deep sleep faster than adults, and can fully wake at the end of a cycle.
- No day-night distinction yet: During the first 2-3 months, their circadian rhythm (internal clock) hasn't developed.
The most effective thing during this period is to give your baby's body day-night cues by keeping the environment bright and active during the day, and dim and quiet at night. Avoiding noise while sleeping and keeping night diaper changes quick also helps.
Remember, frequent waking in newborns isn't a problem—it's a survival instinct. You can think of the first 3 months as "baby mode," and it will pass. Only if sleep-related weight gain is very low or your baby sleeps for more than 3-4 hours without waking and weight gain is slow should you consult your pediatrician.
