A dosing spoon is provided with two bowl portions, each with a front end for oral insertion, a back end, and a top edge along the circumference of the bowl. The spoon also has a handle portion that extends between each bowl. The first and second bowl portions are sized and shaped to contain a 2.5 mL and a 5.0 mL dose, respectively, of a substance with a specific gravity in the range of about 1.1300-1.1700. A rib may be present on the bottom surface of the handle portion to provide both additional stiffening to the handle, as well as a de-nesting feature.
