How long does it take a newborn to settle into a routine?

A newborn typically takes several weeks to a few months to settle into a consistent routine. During the first few weeks, their sleep and feeding patterns may be irregular as they adjust to life outside the womb. By around 6 to 8 weeks, many infants begin to establish more predictable schedules for feeding, sleeping, and wakefulness. However, each baby is unique, and some may take longer to develop a routine.
