A bottle top for use with a baby bottle includes a ring bounding a mouth of the bottle top and being severed latitudinally between upper and lower portions. The upper portion has first and second lower contact faces. The lower portion has opposing first and second upper contact faces. The top includes a nipple coupled to the upper portion which moves between an open position, in which the nipple is away from the mouth and provides access to the mouth, and a closed position, in which the first upper and lower contact faces form a sealing engagement, the second upper and lower contact faces form another sealing engagement, and the nipple is in fluid communication with the mouth.
