The Aiwibi Feeder / Bottle Nipple is a baby feeding nipple made from soft, food‑grade silicone that closely mimics the feel of a mother’s breast to help babies transition smoothly from breastfeeding to bottle feeding. It comes in multiple flow options — from slow (S) for newborns up to faster (XL) for older babies — so you can match the flow to your baby’s age and feeding needs. The built‑in air ventilation helps reduce air intake and colic, while the chew‑resistant yet flexible silicone ensures a comfortable feed. These nipples are easy to clean and sterilize (boiling water, steam or UV), and simple to install onto compatible Aiwibi bottles for everyday feeding.
