A baby bottle is a container designed for feeding infants and young children. It typically consists of a bottle made from plastic or glass, a nipple that mimics a mother's breast, and a cap to prevent spills. Baby bottles are used to hold milk, formula, or other liquids, allowing caregivers to feed babies easily. Baby bottles come in various sizes and shapes, catering to different ages and feeding preferences. Some bottles are designed to reduce colic and gas, while others may have features like wide necks for easy cleaning. They are an essential tool for many parents and caregivers in the feeding process.
