As a new parent, you may wonder if your newborn is dreaming during sleep. While it's difficult to know for sure, some studies suggest that babies do dream, and that these dreams may be important for their development. One study found that during REM sleep, the stage of sleep where most dreaming occurs, infants showed increased brain activity in areas related to learning and memory. Other research has suggested that babies may dream about experiences they've had while awake, which could help them process and learn from those experiences. While we may never know exactly what babies dream about, it's clear that sleep plays an important role in their overall development and well-being.
