Here's a breakdown of the key features of this nipple:

Age and Flow Rate: The "3+" indicates it is suitable for babies who are 3 months and older. This corresponds to a medium flow rate, often denoted by an "M" size. Some variations might also use a "Y-cut" to adjust the flow according to the baby's sucking strength.

Wide Neck Design: This nipple is specifically designed to fit Pigeon's wide-neck feeding bottles. The wider base of the nipple is intended to encourage a wider latch, similar to a baby latching onto a mother's breast.

Material: It is made from 100% silicone, a material known for being soft, flexible, and durable. The texture of the nipple surface is designed to allow the baby to latch on easily and securely.

Anti-Colic System: All Pigeon nipples, including this one, feature an Air Ventilation System (AVS). This system is designed to regulate air pressure inside the bottle, ensuring a smooth milk flow and reducing the intake of air, which can cause gas and colic.

Natural Sucking Pattern: Pigeon's nipples are a result of extensive research on infant feeding. The design aims to replicate the three key steps of a baby's natural sucking behavior: latching on, peristaltic tongue movement, and swallowing. This makes it easier for babies to switch between breastfeeding and bottle-feeding without "nipple confusion."
