The longevity of using a crib or a bassinet will depend on the specific product and the baby's size and development.
Bassinets are typically designed for use during the first few months of a baby's life, or until the baby reaches a certain weight or starts rolling over. This means that the longevity of a bassinet will be limited, and parents may need to purchase a larger sleeping option, such as a crib, once the baby outgrows the bassinet.
Cribs, on the other hand, can be used for several years, from infancy to toddlerhood and beyond. Some cribs can even convert into toddler beds or full-sized beds, providing even longer-term use.
