A sippy cup is a type of drinking vessel designed for young children who are still learning how to use utensils. It typically features a spill-proof lid and a wide, easy-to-grip base that allows kids to hold it without difficulty. The name "sippy cup" comes from the fact that these cups allow children to sip drinks through small openings, rather than having to gulp them down like they would with an ordinary glass or bottle. Sippy cups are often used as a transition between using a baby bottle and holding an adult-style cup, providing a safe and convenient way for kids to enjoy their favorite beverages.
