This 2-pack of Dr. Brown's 9 oz/270 mL weighted straw training cups helps simplify the bottle-to-cup transition for babies 6 months and up. Both BPA-free cups feature soft, weighted straws that allow sipping from any angle, helping babies learn to drink upright. Removable easy-grip handles assist little hands in holding the contoured cups. As baby's skills improve, the handles can be removed for a regular cup. Spill-proof sliding lids keep straws clean and provide on-the-go convenience. With fun coral, olive green and vintage yellow colors, these cups will delight parents and babies. All parts are removable for thorough cleaning and are dishwasher and sterilizer safe. Durable construction withstands typical baby use. Convenient measuring marks help track baby's intake. Offering the same innovative design in two color options, this bundle lets you switch up cups between uses for extra hygiene. The weighted straw function trains babies to sip from cups in preparation for using regular cups. An excellent value for a set of two, these cups ease the bottle transition while making drink time fun.
