Baby bottles are specially designed containers used to feed infants and young children. They typically consist of a bottle, a nipple, and a cap. The bottle can be made from materials like plastic, glass, or stainless steel, while the nipple is usually made of silicone or latex. Baby bottles allow caregivers to provide milk or formula to babies when breastfeeding is not possible. These bottles come in various sizes and shapes to accommodate different feeding needs. Some are designed for specific age groups, while others may have features like anti-colic systems to reduce gas. Proper cleaning and sterilization of baby bottles are essential for ensuring the health and safety of the child.
