Bubonic Plague is the most common naturally-occurring form of plague and is caused by the bite of an infected flea. A sore usually forms at the site of the bite. Plague bacteria enter the skin and travel to the nearest lymph node (gland), usually in the groin, underarm, or neck.
How Long Will My Newborn Sleep? A newborn may sleep up to 18 hours a day, waking every couple of hours to feed. Breastfed babies feed often, about 8 to 12 times a day. Bottle-fed babies tend to feed less often, about every 3 to 4 hours or so. Because the need for food is stronger than the need for sleep at this age, babies who sleep for longer stretches should be awakened to feed.
At 6-12 months. From about six months, babies have their longest sleep at night. Between 6 and 12 months, most babies are in bed between 6 pm and 10 pm. They usually take less than 30 minutes to get to sleep (but about 10% of babies take longer). Most babies can sleep for a period of six hours or more at night and are waking less.
