Trouble in the work place

Hey ladies, so I'm having a little problem on the work place. I've been at my job for almost two years. In that time period I have made friends and great relationships with everyone I work with. A woman that I work with whom I get along extremely well with and is one of my favorite people to work with had her daughter start working with us. Her daughter is a couple years younger than me and has been working with us for a couple months now.

Now I love her mother greatly, shes one of my favorites and we get along great but her daughter has been stepping on everyone's toes. I dont know if she thinks she has a one up one everyone because of her mother but she tries to tell me and everyone how to do our job, tries to tell us what to do, she "tattle tales" on people for very petty things, tries to "correct" us and is just overall extremely rude in her tone while doing this. She comes off extremely arrogant and it's to the point where it has honestly become infuriating.

I have mentioned to her mother before about some of the comments she has made and how it really angered me and bothered me and her mother sounded taken back that she would say something like that. I figured maybe if I mentioned it to her she would kinda tell her daughter and get the hint she needs to back off and stop trying to act all high and mighty and telling people who have been in this job for years how to do there job versus her whole 2 months here.

Anyways, obviously bringing it up to her mother didnt help so now I'm going to have to a conversation with her myself because no one else will do it. I'm nervous if I say something to her it's going to cause tension between her mother and I which I truly dont want. But her daughter is making the work place unbearable. And I'm just hoping once I start a conversation with her that my built up anger (and pregnancy hormones) doesnt get the best of me.

@MS I'm not sure if you maybe misunderstood? I dont foresee a daughter looking at her mothers work friend as being beneath her and disrespecting a friend of her mothers. I personally believe she thinks shes entitled and above others because she is her mothers daughter and her mother has been in this work for a many years.
