There are thousands of lymph node located around the body that help screen out germs in the body serum. There are many in the neck, head & behind the ear. At rest these are often 1/4 inch in diameter (pea sized) and may grow to marble sized when reacting to a stimulus. Bug bites, or viral infections can increase their size.What you describe is normal.If concerned review this with the kids doc.
