I heard babies will grab their ears when they start teething. My son has shown many signs of teething(drooling, biting, fussiness) he is extremely fussy at night and for the past two days he started grabbing his ear.  It's always this ear. So now I'm wondering if he could possibly have an ear infection. Btw he has no fever. I'm gonna make a doc appt tomorrow but I'm just curious on what others think
