How can i get rid of buldging fluid in my babies ear drum he's 7 months old and had it for over 3 months he's been on antibiotics to many times?

See an ENT: If a child has an ear infection which doesn't clear after 2 months of antibiotics, or keeps recurring within less than 2 weeks after antibiotics, you may need to ask your doctor for a referral to an ear, nose, and throat specialist. Tubes are sometimes used to resolve this problem until the baby's own eustachian tubes grow.

Fluid or infection?: V.Howie at ut galveston found that a percentage of normal infants had clear fluid for 3-4 months in the first year without true infection or negative outcome.That said, if the kid has had bulging painful infections that won't clear with multiple meds over 90 days a set of tubes may be needed. Time for a consultation.
