Because at Lansinoh we support breastfeeding and want it to continue even though there may be times when you and your baby can not be together, we have introduced our new bottle line featuring the unique NaturalWaveTM Peristaltic teat, which is clinically proven to help maintain established breastfeeding patterns. Based on over 50 years of research into infant feeding behaviour, this teat has been developed to promote the natural sucking style of babies which involves: latching-on, peristaltic tongue movement and swallowing. The peristaltic movement, which gives the name to the teat, is a smooth wave-like motion of the baby?s tongue, compressing the mother?s nipple to extract milk. With a wide base, the NaturalWaveTM teat encourages a wider latch-on, similar to the baby?s natural latch. Super soft and flexible for optimal compression, this 100% silicone teat allows baby to employ the natural sucking rhythm. As recommended by health professionals, the NaturalWaveTM teat has a gradual slope for improved suction, while the teat?s structure is strengthened with innovative inner vertical ridges to make it collapse resistant so baby can enjoy a comfortable feed. For peace of mind, AVSTM Air Ventilation System reduces intake of air, a potential cause of colic. To meet baby?s changing needs, the one piece, hassle-free NaturalWaveTM teats are available in slow, medium and fast flows. Clinically proven to reduce confusion in established breastfed babies, the NaturalWaveTM Peristaltic teats make it possible to combine breast and bottle feeding with ease and confidence. Pack contains 2x NaturalWaveTM Peristaltic teats.
