A baby bottle with a liquid compartment and a separate dry goods compartment is described. The dry goods compartment and the liquid compartment may be removably sealable from each other by rotating a lower-annular-member with respect to an upper-annular-member； wherein these two annular-members may be disposed between a bottle-main-body and a nipple-member. Each of these two annular-members may have its own respective opening and shelf-portion and may be rotated with respect to each other from an open-configuration to a closed-configuration. In the closed-configuration, dry goods, such as dry baby formula, may be temporarily stored within the dry goods compartment, in a substantially dry condition, separated from a liquid within the liquid compartment. When desired these two annular-members may be rotated into the open-configuration, to allow the dry goods to substantially fall into the liquid compartment, to facilitate mixing with the liquid in the liquid compartment.
