A baby bottle, nursing bottle, or feeding bottle is a bottle with a teat attached to it, which creates the ability to drink via suckling. It is typically used by infants and young children, or if someone cannot drink from a cup, for feeding oneself or being fed. It can also be used to feed non-human mammals.

A "vented" bottle is also sometimes marked as an "anti-colic" bottle.
Infant formula, also called baby formula, simply formula, baby milk or infant milk, is an ultra-processed food designed and marketed for feeding to babies and infants under 12 months of age, usually prepared for bottle-feeding or cup-feeding from powder or liquid. The U.S. Federal Food, Drug, and Cosmetic Act (FFDCA) defines infant formula as "a food which purports to be or is represented for special dietary use solely as a food for infants by reason of its simulation of human milk or its suitability as a complete or partial substitute for human milk".
