1 Place your baby on his or her back to sleep, but don't worry if your little one picks another sleep position. If you have any questions about your baby's sleep position, talk to your doctor.  Make sure your crib meets current safety standards.
Newborn to 6 Months: Infants need about 16 to 20 total hours of sleep per day (and usually wake every two or three hours to chow down). By about four months, most babies sleep ten to 12 hours at night (with a feeding or two) and nap for three to five hours of sleep a day (spaced between two or three naps). At this age, babies typically sleep about 11 hours at night (many straight through) and take two daily naps that add up to three to four hours.
