BREAKING DOWN 'Normative Economics'. Normative statements are often heard in the media because they tend to represent a theory or opinion rather than objective analysis. Normative economics is a valuable way to establish goals and generate new ideas, but it should not be used as a basis for policy decisions.
You may find yourself wondering if your baby can sleep on his stomach, especially if he appears to be more comfortable that way. To prevent Sudden Infant Death Syndrome, or SIDS, which remains a threat until your baby is 12 months of age, it is best for her to sleep on her back, instead of her stomach.
Since babies this age are more awake, alert, and aware of their surroundings during daylight hours, they're more likely to be tired at night and sleep. But the range of normal is still very wide. By 3 months of age, babies tend to sleep about 14 hours a day. Many will have settled into a daily sleep routine of two or three naps during the day, followed by sleeping through the night stretch after a late-night feeding. Again, not all infants keep to the same timetable.
