Kinda gross..but is this bug harmful to my toddler?!?

Last night I noticed this little brown bug that had two little 'pinchers' that curved as a tail..I think it is called an 'earwig' in my home. This is the first time I have ever seen this but is it harmful to my daughter? I have heard the whole superstition about they crawl into ears and eat brain matter but that's just a superstition, correct? So, my question is is it a harmless bug..or should I call a exterminator to come out? I've never seen one in my home before last night, so I am sure if there is one there are more.
