This nipple's many unique features introduce parent and baby to a unique Nûby Non-Drip/No-Spill feeding system. In this first stage, the baby learns how he or she can control the flow rate of the liquid. Since flow rate preferences vary from baby to baby, this is the perfect solution for a less frustrating feeding. The nipple is the closest thing to the mother’s breast that gave baby its first meal. Soft dimples on the nipple provide a constant massage for your baby’s delicate gums. An anti-colic feature is included in the design of the nipple, helping to prevent ingestion of air , thus avoiding the risk of colic. Let your baby feed in the way he/she likes best.
