At around two to three months of age the circadian rhythm begins to emerge which is the internal clock that controls our patterns of sleeping and waking. Hormones control this rhythm and cues from daylight and darkness help to regulate our sleep and awake times. By eight weeks your baby will begin to notice the environmental cues of light and dark and become familiar with different routines surrounding feeding and going to sleep. Before this time your baby’s internal sleep cycle is unorganized and variable. There will be no consistency to how much or how little your baby sleeps before this time. Sleep will organize as your baby grows and develops. At around the eight week mark your baby will get better at organizing day and night and will begin to get a more consolidated stretch of sleep at night.
