Lansinoh’s mOmma Feeding Bottle with NaturalWave Teat has been specially designed so that your little one can enjoy your expressed breastmilk even when you’re apart. Based on more than 50 years of research, the NaturalWave teat promotes your baby’s instinctive sucking action for natural oral development, which helps you switch easily between breast and bottle so that you can maintain your established breastfeeding patterns.Extensive research has revealed that a baby’s sucking style is very different to an adult’s and involves three key steps. These are the initial latching on, the peristaltic tongue movement (in which your baby’s tongue moves in a wave-like motion), and swallowing. It is very important that a baby is able to perform the peristaltic tongue movement as it encourages natural oral and jaw development.Lansinoh’s Natural Wave teat is clinically proven to encourage this natural feeding pattern.Care & Use Lansinoh bottles can be washed in the upper rack of a dishwasher and can be sterilised (open) both in the microwave and using a special sterilising machine.About The Brand Our products, including Lansinoh HPA Lanolin, have been trusted by mums and healthcare professionals to provide safe, effective breastfeeding support.
