For example, the fourth generation of cephalosporins is not recognized as such in Japan. In Japan, cefaclor is classed as a first-generation cephalosporin, though in the United States it is a second-generation one; and cefbuperazone, cefminox, and cefotetan are classed as second-generation cephalosporins. Cefmetazole and cefoxitin are classed as third-generation cephems.
The sleep charts that you see in parenting books and websites are based on how much time parentsâtypically, Western parentsâsay their babies spend sleeping. For instance, studies of Australian babies reveal that the average newborn gets about 16-17 hours of sleep over a 24-hour period.f course, not all of this sleep time occurred at night. One-month-old babies slept an average of 8 hours each night, with 96% of babies getting between 6 and 13.3 hours of nighttime sleep. At 3 months, babies spent more time sleeping at nightâ-10 hours, on average.
By three months, most babies can sleep for about six hours a night and are more alert during the day. If your baby isn't napping regularly, you should start working on a sleep schedule. Sleep experts and parents agree that the key to successful napping is to be consistent: Baby naps at the same time, in the same place, with the same routine each day.
