Inspired by moms and designed by experts, our Natural Start Anti-Colic Baby Bottle has an extra-wide neck and breast-like nipple to help your baby have the most natural bottle-feeding experience. Made from super soft silicone, the nipple is Closer to Nature because it has a special breast-like shape that encourages a natural latch and prevents nipple confusion when switching between bottle and breast. This works by mimicking the flex and movement of mom’s breast, allowing your baby to feed at a pace that feels comfortable and natural to them. It also features an anti-colic valve to prevent the symptoms of colic by ensuring your little one ingests more milk and less air. Suitable from newborn onwards.
