Hegen\'s starter kit is the perfect gift for any new mother or for mothers looking for a switch of brand. It comes with feeding bottles in both sizes. Hegen\'s revolutionary PPSU PCTO bottle allows you to express, store and feed with a single container by simply swapping the bottle\'s feeding head, storage lid and adapter, to convert a feeding bottle into a breast milk storage container or pumping container with any transfer of milk. This minimises wastage and reduces mess making every drop count. It\'s practical \"soft sqaure\" bottle design allows easy grip, space saving and hassle free cleaning. It is easier for babies to hold and optimises storage space as the world\'s first stackable feeding bottle slots together when empty and stacks neatly when filled. What\'s Included in this starter kit: 1 x Hegan PCTO 240ml/8oz Feeding Bottle With Medium Flow Teat 1 x Hegan PCTO 150ml/5oz Feeding Bottle With Slow Flow Teat 2 x Hegen PCTO Breast Milk Storage Lids in White Features: World\'s first patented no screw thread closure, this PCTO (press to close, twist to open) innovation allows the bottle to be pressed on and twisted off easily with zero spillage. Allows one hand closure. Built in anti collic air venting bypasses the milk to prevent aeration, minimising the oxidation of precious nutrients. This reduces excessive air intake and safeguards baby from tummy upsets. Super soft elliptical-shaped silicone teat closely mimics the lactating breast of mum to simulate a natural latching experience, reducing nipple confusion and making it easier to combine breast and bottle feeding. Off centre teat allows baby to feed in a natural upright position, reducing the risk of milk back flow which may cause mid-ear complications. Grows with your baby, the storage container can also be used as a snack cup or to store baby food and snacks.
