I haven't been called a babysitter yet by any of my families but I have on multiple occasions by my parents. It offends me when they call me this because I feel it is meant offensively as they do not agree with my doing this profession as they think it's a waste of my education (they never said it so strongly but this is how they feel) and they worry that I won't be able to get back into my field when I choose to. So in this case, yes it irks me. My parents think it's wonderful I am with my kids but they don't think this was a smart move and tried many times to talk me out of it.
