Yellow liquid from ear. Serious problem?

Hello, The easiest way to tell if your baby might have an ear infection (or any other illness, for that matter) is by observing a change in his mood. If your baby turns fussy, or starts crying more than usual, be on the lookout for a problem. If he develops a fever (whether slight or high) you have another big clue. Ear infections tend to strike after a common cold or sinus infection, so keep that in mind too.You may also notice the following symptoms: Your baby pulls, grabs, or tugs at his ears.Diarrhea or vomiting.Reduced appetite.Yellow or whitish fluid draining from the ear.This doesn't happen to most babies, but it's a sure sign of infection. It also signals that a small hole has developed in the eardrum. (Don't worry – this will heal once the infection is treated.)Unpleasant smell. You may detect a foul odor coming from your child's ear.Difficulty sleeping. Lying down can make an ear infection more painful. So please consult a pediatrician at the earliest.
