A sippy cup is a type of drinking vessel designed for young children who are transitioning from bottles to regular cups. It typically features a spill-proof lid with a spout or straw, allowing toddlers to drink independently while minimizing mess. Sippy cups come in various materials, including plastic and stainless steel, and often have handles for easy gripping. These cups are commonly used for water, milk, or juice, helping children develop their drinking skills. Many parents choose sippy cups that are BPA-free to ensure safety. Some models are designed to be dishwasher-safe, making them convenient for everyday use.
