My 10 month old keeps pulling at her left ear for the last couple days. could she have an ear infection or just be from teething ?

Common mannerism: This is a common question that peds receive If it's not associated with other symptoms such as fever, a recent cold, or irritability, I would advise watching and waiting. If it is associated with poor sleeping, then you could get it checked

Normal habit: I spend a great deal of time looking into ears for worried moms. Without other symptoms like fever it almost never is an ear infection.
