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.
Ferber states by 3-4 months most six month old babies should be able to sleep through the night. He doesn't say how long sleeping through the night is (at least I couldn't find it) but my guess is that he's going by 5 hours.
