Tommee Tippee Closer To Nature Starter Kit is carefully curated for newborns to encourage the switching from breast feeding to bottle feeding. It is designed with an anti-colic valve that reduces excessive air flow to prevent symptoms of colic by ensuring your little one ingests more milk and less air. 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 the baby to be closer to you. Made with soft silicone nipple which has breast-like shape that flexes and stretches like a breast, encourages a natural latch, and helps your baby to feed comfortably at their own pace. Tomme Tippee starter kit is sterilizer safe and can be self-sterilized in microwave in just 3 minutes. The curved shield sits comfortably between baby’s chin and nose and the holes in each side allow extra air flow and prevent the build-up of moisture which helps to protect baby’s delicate skin against irritation. The instinctive action of sucking helps to calm and soothe babies and all parents know there’s nothing more wonderful than a calm, content baby. Tommee Tippee Starter Kit bottles are BPA free, and the lid is leak proof and it prevents accidental spill over.
