What ages are appropriate to use the Aristot Bassinet?

The Aristot Bassinet is suitable for newborns until they reach 18 lbs (8.2 kg) or can sit unassisted, kneel, or pull themselves up, whichever comes first. Once any of these milestones has been reached, you may transition the base into yet another beautiful piece of furniture using one of the Aristot Conversion Pieces.
