My etiquette classes are starting to become parenting classes. Should I tell the father to be more involved instead of relying on me?

I'm a teacher at an international school and a couple of months ago one of my coworkers asked if I would do girly/etiquette classes for his daughter (Katie). She's one of the few mixed Americans in the school and her father (Matt) and his wife (local native woman) divorced a year ago. Katie is very rowdy and abrasive and Matt wanted her to learn manners (table and social) as well as some girly things that she's been asking about that he has no idea what to do like finger nail painting, doing her hair, and other stuff she's curious about.I didn't mind doing this at all since I love little kids, I'm also an American so I know the etiquette he speaks of and it's a good side paying job. But recently Matt has been asking me to do more with Katie that I really think a father should be doing with his daughter. These topics range from asking me talk to her about proper wiping methods for after she goes to the bathroom to asking me to talk to her about boys in her class and how to "focus on school work instead of boys" or if that doesn't get through then "teaching her how to exploit the crushes in her class for her favor." His literal words.I'm starting to feel like my side etiquette job is now bordering parenting topics that Matt himself should be talking to Katie about. I'm not sure if I should continue to do these things he asks, because he is paying me, or if I should talk to him about building a better relationship with his daughter. Are these normal things to teach a little girl who isn't my own daughter? Would it hurt his relationship with her if he didn't go over this with her himself? These are some things I've been wondering about before I talk to him because I don't want to be out of place.EDIT: The daughter in this is 5. I'm 29 and the dad is in his 40s I think.tl;dr: Coworker is paying me to teach his daughter girl stuff and etiquette but now his topics are starting to seem more like things he should bring up as a parent. Are these requests normal or should I talk to him about being more inclusive in his daughter's upbringing? via /r/Parenting http://ift.tt/2CuGW9k
