This well-designed nursing bottle from Nuby promises an end to leaks and messes. It’s made of nontoxic, break-resistant plastic. The non-drip, leak-proof nipple prevents your baby from ingesting air, which can cause gas and colic. Nipple also features a Vari-Flo valve that lets baby control the flow rate, and dimples that gently massage baby's gums and aid in eruption of teeth. The soft and grippy handles are detachable.
