With Closer to Nature Bottles, switching between breast and bottle feeding becomes easier than ever before. Closer to Nature’s award-winning range of Bisphenol A free (BPA) baby bottles are designed to promote content and easy feeding times for parents and baby. We’ve designed the unique, easy-latch-on nipple shape with breastfeeding experts to mimic the natural flex, stretch and movement of breastfeeding. Together with the bottle’s super-sensitive Easi-Vent valve, this encourages your baby’s intuitive feeding action for comfortable, relaxed feeding.
