Imagine a bottle that sterilised itself Well, it's true! The MAM Easy Start bottle does not require a separate steriliser device; the clever design allows you to self-sterilise. That's a great idea for travelling! This great value 11 piece set contains 8 Easy Start Anti-Colic bottles of various sizes, as well as a selection of teats, lids, a handle and they've thrown in one of their great soothers too! No need for a separate steriliserVenting reduces colic by up to 80%Everything you need in one setAll about meSelf-sterilising is as simple as 1-2-3. Unscrew the bottle from its base, fill the base with 20ml of water, add the teat and the bottle over the top, then put the cap on and microwave for 3 minutes. A self-contained, perfectly sterilised bottle. of course, that's not the only thing that Easy Start bottles have to offer! The vented base is proven to reduce colic by 80% to keep your little one relaxed. The ventilation helps to prevent bubbling and foaming and lets your little one have a smooth and quiet feed. Air can escape through the vent rather than being swallowed by your child. The bottles are suitable for use from birth but make a good transition from breastfeeding to bottles, and for your peace of mind, they are completely BPA and BPS-free.
