Use The Philips Avent Natural silicone teat is designed for babies aged 6 months and older and is developed for thick liquids. It features a soft texture with comfort petals that prevent collapse, promoting a natural latch similar to the breast. This allows for easy combination of breastfeeding and bottle feeding. The teat is equipped with an anti-colic valve that prevents air from entering the baby's tummy, reducing the risk of colic and discomfort. The flexible teat with comfort petals ensures resilience and prevents collapse. How to take The Natural Response teat allows control over the milk flow based on the baby's feeding rhythm. Babies can drink, swallow, and breathe at their natural pace, just like during breastfeeding. Milk is released from the teat only when the baby actively sucks, which helps prevent spillage. If milk leaks from the baby's mouth or they gulp it down, it is recommended to try a teat with a slower flow. If the baby plays with the teat instead of drinking, or seems irritated, you can try increasing the flow rate. Contraindications No side effects have been identified with proper use of the product. Philips Avent Natural teats are made from soft and safe silicone, free from bisphenol-A
