How much will my newborn sleep?
Our babies are not born with a well established biological clock. The circadian rhythms that guide when we feel sleepy and alert are not well developed and your newborn is just as likely to sleep during the day as she is in the evening. If she is a typical full term newborn then she will likely sleep for around 16-18 hours each day. Her longest sleep of the day will last between 2.5 and 4 hours and these sleeps will likely be co-ordinated with when she is fed.
