A baby feeding bottle comprising at least two compartments and a disc shaped sealing member. The sealing disc is placed between the compartments to allow the contents of the compartments to be kept separate. By twisting the compartments, holes in the sealing disc are brought into alignment allowing the contents of the compartments to mix. At least one of the compartments may have means for maintaining a warmer temperature, such as double walls enclosing a vacuum. The bottle may have means for determining the temperature of the contents such as temperature sensitive stickers.
