An improved baby bottle whose top is angled to reduce the ingestion of air, which causes gas pain for the infant. The bottle features a glow-in-the-dark bottle measurement strip along the side, to indicate the volume of milk or formula remaining in the bottle. The base and cap of the bottle are removable, and may be assembled as a separate container to carry medicine, fruit juice, a pacifier, or other small items, or used as a pacifier. The base and cap may also be used to measure medicine or dry formula, and the base measurement strip also glows in the dark. Dry formula or other materials may also be stored in the base while it is attached to the bottle.
