Dr told nothing to worry.. y'day early morning baby ws little fussy pulling his hair n noticed a lymph node on the back of his head left side only... He is absolutely well now.... have taken him to dr he told it a small lymph node... Nothing to worry abt it??? My question is whether kids get lymph node without any obvious reasons...????
