An anti-colic baby feeding bottle (10) includes a bottle body (16) having a bottle neck (18), a cap (14) removably fastened to the bottle neck (18), and an elastic teat (12). The teat (12) includes a nipple portion (24) having a fluid-dispensing through-hole (26) and an annular base (28), an annular flange (30) extending radially outward from the annular base (28), a plurality of apertures (32) formed 360° around the annular flange (30), and an annular skirt (40) depending from the annular base (28). The annular skirt (40) is spaced radially inward apart from an inner surface (42) of the bottle neck (18) to define an annular passage (44) having an outer end (46) in air communication with the apertures (32) and an inner end (48) which is normally closed by biasing force of a free end (50) of the annular skirt (40) that presses against the inner surface (42) of the bottle neck (18). |
