My baby sleeps deeply in the first half of the night, but wakes much more frequently toward morning. Why does this happen?

This is very typical and developmentally normal. While babies sleep in deeper (NREM) sleep during the first half of the night, toward morning REM (dream) sleep cycles—which we call light sleep—become more frequent. At the end of each light sleep cycle, there's a brief arousal; most babies drift back to sleep on their own, but some cry and need parent help if they've become used to it. Additionally, melatonin levels drop and cortisol rises slightly as morning approaches; this lowers the arousal threshold. Knowing this is part of sleep architecture, not a problem, can be comforting. Establishing a consistent bedtime routine and waiting a few seconds before responding to middle-of-the-night awakenings, rather than rushing in, gradually supports your baby's ability to transition on their own.
