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.
Of course, once your baby can sit up (usually around 6 months), most bassinets, cradles, or baskets will be too shallow to keep her from pitching over the side. For her safety, your baby should definitely be sleeping in a crib before then.
