The original wide neck teat for a natural latch and smooth transition from breast to bottle. The breast-like shaped teat of the Closer to Nature bottle allows baby to latch on and supports the transition between bottle and breast. The soft silicone teat feels closer to skin, and gently elongates and flexes during feeding to mimic a natural breastfeeding action. The super sensitive valve eliminates excessive air flow, so little ones ingest more milk and less air.
