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.
Nearly all babies are able to sleep through the night by 6 months, but when they do is very different depending on the child. Some infants as young as 3 months old can snooze for six to eight hours at a stretch. Others won't sleep this long until they're 12 months old. But most babies (70 percent) do sleep through the night by the time they hit 9 months, according to the National Sleep Foundation. Sleeping through the night usually means sleeping for eight to 12 hours straight without needing a nighttime feeding. You may have heard that bigger babies and babies who eat solids are better sleepers, but it's not true. Your baby's ability to sleep through the night depends on age, not size or diet.
