My 3-month-old baby is pulling on his ear, but he doesn't have a fever, doesn't seem to be in pain, and is in good spirits. What could it be?

It could be a variety of things causing your 3-month-old baby to grab their ear. It may simply be a normal reflex or it could be a sign of an underlying issue like an ear infection. If your baby is not showing signs of pain or fever and seems to be in good spirits, it may be best to wait until your next doctor's appointment for a proper examination. A doctor can use an otoscope to check the ear and determine if there is any cause for concern. Some children have a high pain tolerance and may have an ear infection without showing obvious symptoms.
