Infant bottles are specially designed containers used to feed babies with liquid, such as formula or breast milk. They typically consist of a bottle body, a nipple, and a cap. The nipple allows the baby to suck and drink, mimicking the natural breastfeeding process. Bottles come in various materials, including plastic and glass, and can have different shapes and sizes to suit the baby's needs. Many infant bottles are designed to be easy to clean and may be dishwasher safe. Some bottles feature anti-colic systems to reduce air intake during feeding, which can help prevent gas and discomfort. Parents often choose bottles based on their baby's preferences and feeding habits.
