What makes the MAM Anti-Colic bottle special MAM Anti-Colic bottles are designed in every feature to make feeding time as easy as possible for baby and parent, from teat to base to shape to materials. The vented base is designed for baby"s comfort and to reduce colic The patented vented base of the Anti-Colic bottle ensures that babies can drink calmly and relaxed. The ventilation holes in the base perfectly regulate pressure balance and airflow. As the unique MAM bottle ventilates via the bottom, milk flows undisturbed without air bubbles, without interruption. Market research and a medical study confirm that the innovative vented base reduces colic in 80% of babies who use it. The result: no more air swallowing, more relaxed drinking and more quiet nights. The MAM Silk Teat has all the advantages of standard silicone: the clear material looks hygienic, it"s odourless and tasteless and silicone doesn"t age. But in addition to this it is extra-soft thanks to special technology from the MAM Design Studio. Babies love the smart Silk Teat because it feels so soft and familiar, like mother"s skin. This makes the switch between bottle and breast especially easy so little ones can relax from day one. That"s why all MAM silicone soothers, bottles and nipple shields (for short term breastfeeding help) are equipped with the MAM Silk Teat. 94% of babies accept MAM teats. The sterilising Anti-Colic bottle can be taken apart in three easy steps and can be sterilised in the microwave quickly and easily without a separate steriliser. It"s ideal for when you"re on the go. MAM teats are available in four flow rates Size 1 Slow Flow: from birth onwards. Size 2 Medium Flow: from 2 months. Size 3 Fast Flow: from 4 months. Size x Cross Cut: from 6 months. MAM teats are interchangeable with all bottles in the MAM range. Box Contains 1 x MAM 130ml anti colic bottle 1 X instruction leaflet
