I am helping out a family friend with her baby, with child care , but sometimes lines have been crossed. (even though i do like her and she's very kind)... She is not 'my ' friend, but is my aunt's friends' daughter. She pays me less than I'd typically get for when i have all her children together (5 kids) but I haven't said anything b/c I wanted to give a 'deal' of sorts, but I am shy in general, and people have said to put your 'business' hat on when it comes to that. She wants me to work only 2 hours soon, but I typically need 3 or 4 for minimum for a shift, as I live a half hour away. How do I ask her for more hours w/out seeming pushy? (for a minimum 3 or 4 hour)
