Understanding Baby Sleep: 4-6 Months

By now, your baby's internal clock has kicked in, and he can differentiate between day and night. He should be on the way toward an established sleep pattern. During this time, babies need an average of 14 hours of sleep per day: At 4 months, a baby can go eight hours at night without a feeding; by 5 months, he can sleep for 10 or 11 hours straight. Babies will sleep four to five hours during the day, spread out over three naps. At 6 months, babies need an average of 11 hours of uninterrupted sleep each night, and 3.5 hours of daytime naps spread over two to three naps.
