Avent Variable Flow Silicone Nipples
The variable flow nipple has a slot instead of holes,... More allowing you to manually vary the flow and is recommended for babies 3 months and up. Unlike other nipples, which limit your babys natural suckling motion, the Avent nipple is carefully designed to closely mimic the form and function of the breast.
With a broad, soft and natural shape that allows baby to suckle with a natural breast-feeding motion, your baby will be able to alternate comfortably between breast-feeding and bottle-feeding.
Ages 3 months and up.
