Infant pacifiers with interchangeable nipples

A method of assembling a pacifier, comprising:

• providing a shield comprising opposite front and rear surfaces, an opening substantially centered within the shield, and an annular sleeve extending from the rear surface, wherein the annular sleeve is circumferentially aligned with a perimeter of the opening, wherein the annular sleeve comprises an inner surface, an outer surface, and a distal free end, and wherein a notch is formed within the inner surface;
• inserting a nipple member through the shield opening, wherein the nipple member comprises an annular base, a nipple extending outwardly from a first end of the annular base, and a flange at an opposite second end of the base, such that the nipple extends outward from the shield front surface;
• aligning an outwardly extending rib of the annular base with the notch in the annular sleeve inner surface to limit relative rotation of the nipple member and shield;
• positioning the flange to abut the distal free end of the shield annular sleeve;
• and
• securing a cap to the shield annular sleeve to maintain engagement of the nipple member and shield, wherein the cap is removably secured to the shield annular sleeve.
