During the Middle Ages, bubonic plague was known as the Black Death.. During that time many people became sick and died of pneumonia when the bubonic plague bacteria infected the lungs, called the pneumonic plague which saw the spread of the disease bacteria through coughing and sneezing.
From experience with my own kids as well as asking some other moms and doing some research on popular baby websites, it seems to be the average time a baby sleeps in their bassinet is approximately 3 months or around 9 weeks â 13 weeks.
In fact, babies consolidate daytime sleep in the first 4-9 months and go from 3-4 naps per day at 4 months to 2 naps per day by 8-9 months. So, try for 1-2 long (45-120 minute) naps in the crib, co-sleeper, or bassinet, but also try and get out for a walking or flexible nap every day.
