Why might a baby get recurring ear infections?

Child many ear infec: We see this frequently in pediatrics, "atopic dx". Sometimes children get another ear infection as soon as they stop their antibiotic. The most common reason is a highly allergic child, who often will have eczema too. These children do very well with dairy-free diets and sometimes removal of other foods too depending on allergy testing. Ear tubes can usually be avoided!

Collection of issues: The middle ear requires drainage of a mucus created by its walls, the drain has tiny tube size initially that enlarges with age. Infants have recurrent illnesses, many of them in the respiratory tract as it builds its immune system. The tiny tubes block easily with colds, throat germs invade, ear infections occur. As the kid/head grows, this becomes less common. There are other factors.
