The Lansinoh NaturalWave™ Teats XS is specially designed for newborns and babies who require an extra slow milk flow. Made from ultra-soft, flexible silicone, it adapts gently to your baby’s palate while supporting a natural sucking rhythm ideal for combining breastfeeding and bottle feeding.  Its wide-base design encourages a secure latch, mimicking the natural breastfeeding position and helping reduce nipple confusion. The integrated anti-colic air ventilation system minimises air intake, reducing the risk of gas and discomfort during feeds.
