Now your baby can transition from breast to bottle in a natural way with NUK® Simply Natural™. Designed to mimic the fit, flow and movement of mom as closely as possible, this is the only bottle with up to nine nipple holes, just like mom, providing a natural feeding experience to ensure the mom-baby bond remains strong. Now our bottles feature an even softer nipple. NUK® Simply Natural™ nipples mimic the shape mom's breast takes while breastfeeding. The scoop nipple cavity allows space for baby's tongue and jaw to move naturally, just like they do when breastfeeding.
