what cause lymph nodes to enlarge behind a toddler's ear?

Inflammation: Lymph nodes enlarge when they are fighting an inflammatory area which is in the region of the node. Your toddler may have had a cold, a slight cut, or any other form of irritation leading to inflammation. If it gets increasingly larger, tender, hot, red, new nodes develop, see your doctor.
Dr. James Ferguson

All sorts of things: This can mean something as simple as a bug bite near the area or local skin irritation to a body reaction to a vaccination. The nodes in the neck and around the back of the skull are not buried in tissue like they are in the rest of the body, so they are easily noticed.They are the bodies serum cleaners and react when stimulated.They grow and become sensitive when working and shrink as they finish

Knot on toddler head: Most knots on children's head, if they are discreet, mobile, not red or hurt on touching, are benign lymph nodes which get enlarged due to minor trauma, inflammation or skin infection of scalp region like dandruff or scalp ring worm etc. A short visit to your pediatrician or to a minute clinic would solve this "mystery" in no time!
