This 4-pack of MAM bottle nipples bundled with a MAM trainer cup is designed to support your baby's feeding needs at multiple developmental stages. The nipples feature a unique flat, symmetrical shape modeled after the natural shape of a mother's nipple during breastfeeding. This allows for a comfortable latch and easy transition between breast and bottle. The bundle contains 2 Level 3 fast flow nipples for babies 4+ months and 2 Level 4 extra fast flow nipples for thicker liquids and babies 6+ months. These BPA-free silicone nipples have a textured SkinSoft surface that feels similar to skin. The 8-ounce MAM trainer cup includes both a spill-free nipple and extra-soft spout to help babies transition from sucking to drinking independently. The protective dust cap doubles as a measuring cup, while the non-slip handles support self-feeding. The wide top openings on both the nipples and trainer cup allow for easy filling and thorough cleaning. With 94%** of babies accepting the MAM nipple shape and innovative design features like air valves to prevent nipple collapse, this bundle provides a complete feeding solution tailored to your child's needs.
