Why bottle feeding contribute to otitis media lymphatic?

Bottle feeding can contribute to otitis media, or middle ear infection, due to the way infants are positioned during feeding. When babies are bottle-fed, especially while lying down, the milk can flow into the Eustachian tubes, increasing the risk of fluid buildup in the middle ear. This fluid can become infected, leading to otitis media. Additionally, the act of sucking from a bottle may not promote the same drainage and ventilation of the ear that breastfeeding usually encourages.
