Your newborn baby will sleep as much as his body needs.
Newborns can drop off to sleep in any situation.
Since babies are not born with the ability to distinguish night and day, this is something you can teach your new baby. While you may not get a newborn to sleep, you can make a sleepy baby more comfortable. At bedtime or naptime, be sure the baby has burped and has on a dry diaper. Put the baby in a crib on his back or side. Remove the infant when he wakes up.
