A baby nursing bottle having inner and outer nipples each connected through special valving means to opposite ends of the nursing bottle so as to permit an adequate flow of milk irrespective of the position of the bottle. The special valving means comprise small flexible flaps disposed in the direction of flow of fluid. Similar valve means are incorporated into the outer nipple in a position to allow air to enter into the bottle to replace the displaced milk.
