When parents fall asleep, babies continue their small but very intensive exploration of the world. The nighttime hours are when numerous amazing processes occur, often going unnoticed in the daytime hustle.
Behind closed eyelids, babies aren’t just sleeping—they’re processing information received during the day, strengthening memory, and developing their skills. Research shows that infants’ brains activate during sleep, and it’s precisely in this state that new connections form between nerve cells. This helps develop speech, motor skills, and emotional resilience.
Interestingly, babies can show activity during sleep—for example, they might smile, pose, or even make sounds and gestures. These are manifestations of their inner emotional world and new sensations acquired during the day. Sometimes babies “talk” in their sleep or make their first attempts to crawl, as if training their muscles and skills even while resting.
Moreover, nighttime sleep activates the body’s growth and recovery processes. Babies strengthen their immunity, renew tissue cells, and store energy for new daytime achievements. Some studies have even recorded cases where babies “learn” to play or speak in their sleep, demonstrating the remarkable plasticity of their developing brains.
Thus, nighttime isn’t just about rest. It’s a magical time for development and new discoveries that helps babies grow smarter, stronger, and happier—even when they don’t realize it themselves.
