Abstract: A bottle lid for use with a bottle having an opening includes an intermediate lid having a configuration for selectively coupling the intermediate lid to the bottle. The intermediate lid includes a barrier presenting upper and lower faces, the barrier enclosing the bottle opening when the intermediate lid is coupled to the bottle. The bottle lid includes a secondary bottle defining a cavity. The secondary bottle has an upper end open to the cavity and includes a configuration complementary to a configuration of the barrier lower face for selectively coupling the secondary bottle upper end to the barrier lower face. The bottle lid includes a top lid having a configuration complementary to a configuration of the intermediate lid for selectively coupling the top lid to the intermediate lid. The top lid and the intermediate lid collectively define a sealed compartment when the top lid is coupled to the intermediate lid.
