Naturally sustainable and long-lasting Start creating a better future for the next generation with this naturally sustainable and long-lasting glass baby bottle. Made from durable medical grade glass that is naturally stain resistant and free from BPA, phthalates and toxins. Super soft, breast-like teat Made from super soft, resilient silicone, this bottle teat features a matt texture that feels closer to skin for complete comfort at feeding time. Designed with breastfeeding experts, our baby bottle teats are shaped like a breast because babies prefer it that way. The patented ripple design allows the teat to mimic the natural flex, stretch and movement of a mum’s breast to support in the transition between breast and bottle. Closer to Nature teats are only compatible with Closer to Nature bottles. And you should change them immediately if they're damaged, weak or have been bitten by tiny teeth. Anti-colic Featuring an Easi-vent valve that reduces excessive air flow, so little ones ingest more milk and less air, preventing symptoms of colic. Together with the bottle’s sensitive valve, the wide bottle neck encourages your baby’s intuitive feeding action. Designed to be held in the most natural position during feeding, the compact shape of the bottle also allows baby to be closer to you. Easy to clean The wide neck bottle makes cleaning easy, and the bottles are suitable for use in the dishwasher, microwave and steam sterilisers. Simply unscrew your baby bottle into three parts for easy cleaning and sterilising.
