Babies may not be able to create their own sleeping and waking patterns.
Help your newborn baby shift sleeping schedules by ensuring there’s plenty of light and social interaction during the day. Also, by waking him every 2-3 hours during the day to feed, so his or her body gets used to taking in plenty of calories during the day. At night, from approximately 7:00 p.m. to 7:00 a.m., make the baby’s environment dimmer and less stimulating, with quick feeds and changes before putting him right back to bed.
