Сон Новорождённого

The term **"Сон Новорождённого"** translates from Russian as **"Sleep of the Newborn"** or **"Newborn's Sleep"**. It usually refers to the pattern, characteristics, and stages of sleep in newborn babies—typically describing how infants sleep for many short periods throughout the day and night, cycling rapidly between active (REM‑like) and quiet sleep phases.
