Featuring a classic Disney Mickey illustration, This NUK First Choice+ bottle includes the First Choice+ Teat which replicates a mother's nipple during breastfeeding and features the special, orthodontic, asymmetrical NUK shape, an extra wide lip support and a new extra soft tip to fit baby's mouth perfectly, simulating breastfeeding as closely as possible - so true to nature that most babies hardly notice the difference.The NUK improved Anti-Colic Air System helps to prevent colic by allowing air to flow into the bottle through a vent, ensuring that no air is swallowed during feeding.
