The 5 BPA-free Natural bottles included in this kit feature wide breast-shaped nipples with unique comfort petals promoting natural latch on and making it easy to combine breast and bottle feeding.

The Formula Dispenser holds 3 pre-measured portions of milk powder and is ideal for travel. The Bottle Brush's curved brush head and molded tip cleans hard to reach areas. The Newborn Silicone Pacifiers have soft, long-lasting silicone nipples and their orthodontic, flat, symmetrical shape respect the natural development of palate, teeth and gums.
