A teething device can include a base having a handle, and a coupling on an opposite end. The base and coupling can be formed from a first material having a first hardness. A reservoir may be configured to contain a liquid therein. The reservoir may be coupled and sealed to the base coupling and configured to provide a watertight seal. The reservoir can have at least one self-sealing aperture. The self-sealing aperture can have a default position wherein the self-sealing aperture is configured to be substantially closed to essentially prevent the liquid from flowing therethrough, and a flexed position wherein the self-sealing aperture is configured to be opened to allow the liquid to flow therethrough. In addition, the reservoir can be formed from a second material having a second hardness that is softer than the first hardness.
