In one aspect, the present invention is directed to a baby bottle apparatus, comprising: a nipple (11); a liquid container (12); a flexible tube (17) connecting the nipple to the container; a normally-closed valve, for controlling the flow of fluid from the container (12) to the nipple (11); at least one lever (13), for opening the valve for fluid passage from the container to the nipple; thereby allowing a user to control fluid flow from the baby bottle apparatus. Preferably, the mechanism for limiting the distance between the parallel bars comprising a rotatable ring (15) having a different outer diameter therealong, such that a movement of each of the levers (13) is limited by the ring (15).
