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.
If this is your situation, make the switch at least six to eight weeks before you're due. You want your toddler well settled in his new bed before he sees the baby taking over his crib. Depending on your toddler's age, you could also consider delaying the switch until the new baby is 3 or 4 months old. Your newborn will probably spend those months sleeping in a bassinet anyway, and your toddler will have time to adjust to the new baby, making the transition to a bed easier when it does happen. Be sure to base the timing of the switch on your child's readiness rather than on the need to free up the crib, however.
